THERMOFORMED POLYCARBONATE/GLASS LAMINATES AND APPLICATIONS

THEREOF

FIELD OF THE DISCLOSURE

[0001] The present disclosure relates to thermoformed laminates, and in particular thermoformed laminates of a polycarbonate material and glass sheet and applications thereof.

BACKGROUND OF THE DISCLOSURE

[0002] An electronic device can have a control panel where a user can interact with the electronic device. The control panel can have layers that can include a display source, a touch sensing device, and/or a cover window disposed over a touch sensing device. The control panel can display information to a user and interpret the user's physical contact with a surface of the control panel. A user can interact with the electronic device by touching the surface of the cover window. An image can be projected through the panel from the display source. The cover window can include glass which can provide a transparent protective layer and can cover the touch sensing device. Glass can be transparent and can be resilient to abrasion and thus can be suitable as a cover window. However, glass can be brittle and susceptible to cracking and failure (e.g., when impacted along an edge). Additionally, it can be difficult for polymer resin to adhere directly to a glass substrate. Additives, surface treatments, and/or adhesives can be used in an effort to improve the adhesion, yet an interface between the glass and the polymer resin can remain a weak point where separation can occur.

[0003] These and other shortcomings are addressed by aspects of the present disclosure.

SUMMARY

[0014] Aspects of the disclosure relate to a laminate including a first layer comprising a polymeric material and a second layer comprising a glass sheet thermoformed to the first layer.

[0015] Other aspects of the disclosure relate to an article of manufacture including a laminate, the laminate comprising a first layer comprising a polymeric material and a second layer comprising a glass sheet thermoformed to the first layer.

[0016] Further aspects of the disclosure relate to methods for making an article of manufacture, including thermoforming a glass sheet to a first layer comprising a polymeric material. DETAILED DESCRIPTION

[0017] Aspects of the disclosure will now be described in detail with reference to the figures, wherein like reference numerals designate identical or corresponding parts throughout the several views, unless specified otherwise.

[0018] With reference to FIG. 1, an aspect of the present disclosure relates to a laminate

10 including a first layer 100 including a polymeric material and a second layer 200 including a glass sheet to which the first layer 100 is thermoformed.

[0019] The laminate 10 can be any shape, such as flat, curved, shaped to conform to a mold or the like. Each of the first layer 100 and the second layer 200 can have a thickness suitable for the article in which the laminate may be located. In certain aspects, each of the first layer 100 and the second layer 200 can have a thickness of from about 0.05 millimeters (mm) to about 5.0 mm thick, such as for example, about 0.05 mm to about 1.5 mm, or from about 0.3 mm to about 1.0 mm, or from about 0.4 mm to 1.0 mm, or even from about 0.55 mm to 0.7 mm as measured in along the shortest dimension of the laminate 10.

[0020] The first layer 100 can have a first surface 110 and a second surface 120.

Similarly, the second layer 200 can have a first surface 210 and a second surface 220. A surface (e.g., the first surface 110) of the first layer 100 can be thermoformed (e.g. adhered) to a surface (e.g., the second surface 220) of the second layer 200 to form the laminate 10.

[0021] A typical thermoforming process involves several steps including but not necessarily limited to: design; materials selection; tooling; thermoforming and trimming. Design involves creating a model (e.g., CAD model) or drawing of the article to be thermoformed, and optimizing the design for the thermoform process. After the final design is ready, the materials to be used for the article are selected. A material is selected based on its functional and aesthetic characteristics. Different materials have different physical properties and benefits, and some may work better for a particular thermoform design than others. Tooling involves creating a mold that the material will be heated in. Molds may be made from various materials; aluminum is one exemplary mold material. When the mold is ready, the article may be thermoformed by forming the selected material to the mold. The material (e.g., polycarbonate resin) is heated to a pliable temperature and then shaped to the mold using vacuum pressure, air pressure or a combination of each. Once the material has been formed to the mold, it is cooled and removed from the mold, retaining its final shape. One benefit of thermoforming is that because the article cools against the mold surface under ambient temperatures, the thermoformed article typically has a much lower residual stress as compared to articles formed by other processes (e.g., injection molding). Finally, once the article is thermoformed and cooled, it may be trimmed or cut into a desired shape. Secondary operations such as cutouts, through-holes and other features that require the removal of material can also be performed on the article.

[0022] Accordingly, aspects of the present disclosure relate to a laminate 10 formed by thermoforming a first layer 100 including a polymeric material to a second layer 200 including a glass sheet.

[0023] With reference to FIGS. 2 A and 2B, in some aspects a laminate 10 includes at least one additional layer (e.g., a third layer) 150 thermoformed to the first layer 100 or the second layer 200. The at least one third layer 150 may also include a polymeric material. The at least one additional layer 150 may be thermoformed to the second layer 200 as illustrated. In such aspects the second layer 200 including the glass sheet would be "sandwiched" between the first layer 100 and the at least one additional (e.g., third) layer 150. In other aspects the at least one additional layer 150 could be thermoformed to the first layer 100 (not shown).

[0024] Thermoforming of the second layer 200 including the glass sheet between two layers (e.g., first layer 100 and at least one additional layer 150) may in some aspects result in cracking of the glass sheet in the second layer 200. Cracking of the glass sheet in the second layer 200 may result in the second layer having an opaque appearance, so it may also be desirable for the first layer 100 and/or the at least one additional layer 150 to have an opaque appearance so that the cracked glass in the second layer 200 would not be visible.

[0025] In some aspects (not illustrated), a plurality of additional layers 150 are thermoformed to the first layer 100 or the second layer 200. Thus, not including any adhesive layers or functional layer(s) (described below), the laminate 10 may include a third layer, a fourth layer, a fifth layer, etc.

[0026] A thermoformed laminate 10 including a first layer 100, a second layer 200 including a glass sheet, and at least one additional (third) layer 150 may be useful in a wide variety of applications. The second layer 200 including the glass sheet would have a different density than the first layer 100 and the at least one additional layer 150, and would thus provide the laminate 10 with good sound and moisture barrier properties. Accordingly, in one particular example the laminate 10 could be incorporated into an automotive panel, such as a dashboard. Another benefit of such a laminate 10 is that it would provide sound and moisture barrier properties at a relatively light weight compared to current dashboard materials used in the industry.

[0027] In some aspects the laminate 10 includes at least one adhesive layer 400, which provides additional adhesive strength between the layers of the laminate 10 in which the at least one adhesive is located. The at least one adhesive layer 400 can thus be disposed adjacent to a surface of the laminate 10. For example, the at least one adhesive layer 400 can be disposed between the first layer 100 and the second layer 200, or between the second layer 200 and the at least one additional (e.g., third) layer 150, or between the first layer 100 and the at least one additional layer 150. In certain aspects a plurality of adhesive layers 400 could be provided, for example between the first layer 100 and the second layer 200, and between the second layer 200 and the at least one additional layer 150.

[0028] The at least one adhesive layer 400 can be applied with any thickness suitable to ensure that the layer(s) of the laminate are sufficiently adhered to one another. In some aspects, the thickness of the at least one adhesive layer 400 is less than about 2.0 mm, for example, about 0.05 mm to about 1.0 mm, or about 0.2 mm to about 0.8 mm. The at least one adhesive layer 400 can be sandwiched between, e.g., the first surface 110 of the first layer 100 and the second surface 220 of the second layer 200. The at least one adhesive layer 400 can be in mechanical communication with, e.g., the first surface 110 of the first layer 100 and the second surface 220 of the second layer 200. The at least one adhesive layer 400 can be applied to, e.g., the first layer 100, or to the second layer 200, or to both the first layer 100 and the second layer 200. The at least one adhesive layer 400 can be applied using any desirable process including but not limited to roll lamination, roller coating, screen printing, spreading, spray coating, spin coating, dipping, a combination thereof and/or the like.

[0029] The adhesive in the at least one adhesive layer 400 can be any adhesive that can withstand exposure to a molding process (e.g., exposure to a mold tool temperature of up to 200°C and/or molding material temperature of up to 360°C) and which will not chemically attack the first layer 100 or the second layer 200. Chemical attack can be determined by forming a sample that includes the selected adhesive and comparing the physical properties of the sample before and after it is placed in a 1700-2000 pound per square inch (psi, gauge) (11.7 to 13.8 MegaPascal (MPa)) strain fixture and held at a temperature of 70°C for 1 week. If the mechanical properties (e.g., tensile strength, flexural modulus, and the like) are greater than or equal to 95% of their original value (before the 1 week test) and there are no visual signs of attack (e.g., stress cracks) then the adhesive can be considered to not attack the substrate material. In aspects of the present disclosure, the adhesive is a hindered amine light stabilizer free ethyl vinyl acetate (HALS free EVA), thermal plastic urethane (TPU), epoxy, acrylate, amine, urethane, silicone, ethyl vinyl acetate (EVA), or a combination thereof.

[0030] The adhesive can be optically clear, such as providing a transmittance of visible light of greater than or equal to 90% as determined per ASTM D1003-00. The adhesive can be opaque, such as colored to match the first layer 100 or the second layer 200. The first layer 100 or the second layer 200 can be opaque, or can be optically clear such as providing a

transmittance of visible light of greater than or equal to 90% as determined per ASTM D1003- 00. The adhesive can include a polymer, such as a thermosetting polymer or a thermoplastic polymer. The thermosetting polymer can be activated by electromagnetic radiation (e.g., electromagnetic radiation in the ultraviolet (UV) spectrum having frequencies of 750 THz to 30 PHz), electron beam, heat, drying, exposure to air, pressure (e.g., pressure sensitive adhesives) or a combination thereof. The adhesive can be applied between the first layer and the second layer to couple them together so as to prevent separation. When the layers are coupled in this way, the first layer 100 can exhibit an adhesion to the second layer 200 of greater than 3 lbf (pounds force) per linear inch (525 Newtons per meter (N/m)) as determined by a 90 degree peel test.

[0031] As discussed, the laminate 10 includes a first layer 100 including a polymeric material, and optionally at least one additional (third) layer 150 that may also include a polymeric material. In some aspects each of the polymeric material of the first layer 100 and at least one additional layer 150 independently includes a thermoplastic polymer, a thermoset polymer, or a combination thereof. Possible thermoplastic polymers include, but are not limited to, oligomers, polymers, ionomers, dendrimers, copolymers such as graft copolymers, block copolymers (e.g., star block copolymers, random copolymers, and the like) or a combination thereof. Examples of such thermoplastic resins include, but are not limited to, polycarbonates (e.g., blends of polycarbonate (such as, polycarbonate-polybutadiene blends, copolyester polycarbonates)), polystyrenes (e.g., copolymers of polycarbonate and styrene, polyphenylene ether-polystyrene blends), polyimides (PI) (e.g., polyetherimides (PEI)), acrylonitrile-styrene- butadiene (ABS), polyalkylmethacrylates (e.g., polymethylmethacrylates (PMMA)), polyesters (e.g., copolyesters, polythioesters), polyolefins (e.g., polypropylenes (PP) and polyethylenes, high density polyethylenes (HDPE), low density polyethylenes (LDPE), linear low density polyethylenes (LLDPE)), polyamides (e.g., polyamideimides), polyarylates, polysulfones (e.g., polyarylsulfones, polysulfonamides), polyphenylene sulfides, polytetrafluoroethylenes, polyethers (e.g., polyether ketones (PEK), polyether etherketones (PEEK), polyethersulfones (PES)), polyacrylics, polyacetals, polybenzoxazoles (e.g., polybenzothiazinophenothiazines, polybenzothiazoles), polyoxadiazoles, polypyrazinoquinoxalines, polypyromellitimides, polyquinoxalines, polybenzimidazoles, polyoxindoles, polyoxoisoindolines (e.g.,

polydioxoisoindolines), polytriazines, polypyridazines, polypiperazines, polypyridines, polypiperidines, polytriazoles, polypyrazoles, polypyrrolidones, polycarboranes,

polyoxabicyclononanes, polydibenzofurans, polyphthalamide, polyacetals, polyanhydrides, polyvinyls (e.g., polyvinyl ethers, polyvinyl thioethers, polyvinyl alcohols, polyvinyl ketones, polyvinyl halides, polyvinyl nitriles, polyvinyl esters, polyvinylchlorides), polysulfonates, poly sulfides, polyureas, polyphosphazenes, polysilazanes, polysiloxanes, fluoropolymers (e.g., polyvinyl fluorides (PVF), polyvinylidene fluorides (PVDF), fluorinated ethylene-propylenes (FEP), polyethylene tetrafluoroethylenes (ETFE)), polyethylene naphthalates (PEN), cyclic olefin copolymers (COC), or a combination thereof.

[0032] More particularly, a thermoplastic resin can include, but is not limited to,

LEXAN™ FST), a polyester, a polyacrylate, a polyamide, a polyetherimide, a polyphenylene ether, or a combination thereof. The polycarbonate can include copolymers of polycarbonate (e.g., poly carbonate-poly siloxane, such as polycarbonate-poly siloxane block copolymer, polycarbonate-dimethyl bisphenol cyclohexane (DMBPC) polycarbonate copolymer (e.g.,

[0033] In some aspects of the disclosure, the polycarbonate resin is a high purity polycarbonate resin. High purity polycarbonate resins are generally characterized as having a purity of at least about 99.70%, a hydroxyl content less than 100 parts per million (ppm) by weight, and which contains less than 2 ppm sulfur, although other purity criteria could be applied. In certain aspects, the polycarbonate resin included in molded articles of the disclosure is produced from a bisphenol A polymer having a purity of at least about 99.70%, a hydroxyl content less than 100 ppm by weight, and which contains less than 2 ppm sulfur.

[0034] As discussed, the laminate 10 includes a second layer 200 including a glass sheet.

GORILLA™ glass.

[0035] Any of the layers described herein (including the first layer 100, second layer 200, or at least one additional layer 150) can also include a filler material such as a reinforcing fiber

TM TM

(e.g., carbon fiber filled polycarbonate resin such as LNP THERMOCOMP Compound, commercially available from SABIC's Innovative Plastics business). Other suitable filler materials include, but are not limited to, carbon fiber, glass fiber, aramid fiber, basalt fiber, quartz fiber, boron fiber, cellulose fiber, natural fiber, liquid crystal polymer fiber, high tenacity polymer fiber (e.g., polypropylene, polyethylene, poly(hexano-6-lactam), poly[imino(l,6- dioxohexamethylene) imnohexamethylene]), or a combination thereof.

[0036] Any of the layers described herein (including the first layer 100, second layer 200, or at least one additional layer 150) can be decorated on any of their surfaces (e.g., the first surface 110 or the second surface 120 of the first layer 100) using any of a number of decorating techniques including but not limited to screen printing, pad printing, metallization, digital printing, gravure printing, offset printing, laser marking, laser printing, etching, texturing, and the like.

[0037] With reference to FIGS. 3A-3D, certain aspects of the present disclosure relate to an article 20, the article 20 including the laminate 10 and at least one molded component 300 adhered to the laminate 10. Aspects of the laminate 10 associated with the article 20 are described above. FIG. 3 A illustrates an exemplary article 20, and FIG. 3B is a cross section taken at line A-A of the article 20 of FIG. 3 A.

[0038] The at least one molded component 300 can include any suitable material, including but not limited to thermoplastic, glass, wood, metal, ceramic, stone, reinforcing fiber, and combinations thereof. Suitable reinforcing fibers include but are not limited to carbon fiber, glass fiber, aramid fiber, basalt fiber, quartz fiber, boron fiber, cellulose fiber, natural fiber, liquid crystal polymer fiber, high tenacity polymer fiber (e.g., polypropylene, polyethylene, poly(hexano-6-lactam), poly[imino(l,6-dioxohexamethylene) imnohexamethylene]), and combinations thereof.

[0039] The at least one molded component 300 can be any shape. The at least one molded component 300 can be bonded to the laminate 10, such as the first layer 100 of the laminate. In this way, the at least one molded component 300 can be bonded with strong adhesion to the first layer 100 which in turn can be adhered to the second layer 200 with strong adhesion (e.g., a adhesion value of 3 lbf per linear inch as determined by a 90 degree peel test or as determined by temperature cycling at -40°C to 85°C at 85% RH with 1 hour dwells at each temperature for 10 to 50 cycles, or by submersing the sample in boiling water for between 5 and 20 minutes, and then checking for signs of delamination). [0040] The at least one molded component 300 can be molded to the laminate 10 in a molding process. For example, the laminate 10 including the first layer 100 and second layer 200 can be positioned in a mold cavity and a polymeric material of the at least one molded component 300 can be injected into the mold cavity to bond to the first layer 100 of the laminate 10 to form the article 20. The molding process can incorporate known technologies within the art such as injection molding, injection compression molding, gas assist molding, foam molding, multi shot molding, multi stage molding, compression molding, or a combination thereof.

Tooling that improves flow, surface finish, and weld strength of knit lines within a molded part such as induction heating and heat/cool technology can be used to reduce injection pressures, improve surface finishes, and promote improved bond strength between the at least one molded component 300 and the laminate 10. The laminate 10 can be held in position within the mold cavity during the molding process using any technique known in the art. The laminate 10 can be held in place by a pressure differential such as vacuum applied to an area of the laminate 10 through passages in a mold section. The laminate 10 can be held in place by pins extending from a mold section into the mold cavity. The pins can be spring loaded to ensure sufficient pressure is applied to the laminate 10 to maintain its position during the molding operation. Spring loaded pins can account for variation in the thickness of the laminate 10 from part to part during production of multiple articles. The laminate 10 can be held in place by a static charge. The laminate 10 can be held in place by core shutoffs that can extend out from the cavity and can form a feature (not illustrated) that the laminate 10 can fit over. The laminate 10 can be held in place by closing the core side of the tool onto the laminate and thus creating a shutoff between the core, cavity, and laminate 10 over an area or a multitude of areas. The laminate 10 can be held in place by a combination of pins, static, shutoffs, mold features, and pressure differential as described above.

[0041] The at least one molded component 300 can include a polymer, a filler material, a polymer additive, or a combination thereof. Suitable filler materials include materials such as those described above. In some aspects the filler material includes reinforcing fiber. The filler material can be in any desirable form for use in a molding operation, such as chopped filler material. The at least one molded component 300 can include 0.1 to 50 weight percent (wt. %) filler material, for example, 5 wt.% to 40 wt. %, or, 15 wt. % to 30 wt. %, or, 20 wt. %. In an aspect, the at least one molded component 300 can include 5 wt. % to 25 wt. % carbon fiber, or 20 wt. %. In an aspect, the at least one molded component 300 can include 5 wt. % to 40 wt. % glass fiber or glass bead, or 30 wt. %. Incorporating a filler material can reduce shrinkage of the at least one molded component 300 after a molding operation, which can prevent the article 20 from undesirable warping. When the at least one molded component 300 is molded from unfilled polymeric resin, the article 20 can be placed in a fixture after molding to prevent it from warping.

[0042] While not required, the at least one molded component 300 can be adhered to the laminate with an adhesive layer. The adhesive in the adhesive layer can be any of the adhesive materials described herein.

The adhesive layer, when included, may enhance the bond between the at least one molded component 300 and the laminate 10. In some aspects an adhesive layer may be omitted, such as when the materials of the laminate 10 and at least one molded component 300 - and the manner of adhering the laminate to the at least one molded component - result in a strong enough bond that an additional adhesive is not required.

[0043] With further reference to FIGS. 3C and 3D, in some aspects the laminate 10 and/or the article 20 includes at least one functional layer 500 that provides additional features to the laminate 10 or to the article 20. The at least one functional layer 500 may be adhered to the laminate 10, such as to the first layer 100 and/or the second layer 200 of the laminate 10. An adhesive layer including an adhesive such as one or more of those described herein may be included between the at least one functional layer 500 and the laminate 10 and/or at least one molded component 300 as desired or required. FIGS. 3C and 3D illustrate exemplary aspects of articles 20, and are cross sections taken along line A-A of the article of FIG. 3 A.

The at least one functional layer 500 may include at least one of a film, a coating, a coextruded layer, a deposited layer or a molded layer. [0045] In some aspects, the at least one functional layer 500 includes a conductive coating as is described in International Application No. PCT/IB2015/052885 and International Application No. PCT/IB2015/02884, the entirety of each is incorporated herein by this reference. Furthermore, the conductive coating can be transferred to the first layer 100 or second layer 200 with a transfer resin as described in International Application No. PCT/IB2015/052885. For example, the at least one functional layer 500 can include a conductive coating formed from conductive nanoparticles, including conductive nanoparticles, conductive metal nanowires, carbon allotropes such as carbon nanotubes, graphene, etc., and combinations thereof. Metal nanoparticles can include copper and silver nanoparticles. A metal mesh film can be used having a regular network. Transmittance can be about 70% to about 80% and resistance, measured in Ohm/square can be less than 0.5. Conductive coatings can be formed from conductive metal nanoparticles formed into a patterned network of conductive traces and transparent cells, i.e., voids having few nanoparticles. The network can be random or regular in shape, the

transmittance can be about 70%, and the resistance can be less than 0.05 Ohm/square. The transparent cells can have sizes of less than 1 mm, for example, less than 0.5 mm, for example, less than 0.25 mm. Transparent conductive coatings are described, for example, in U.S. Pat. No. 7,601,406, the entirety of which is incorporated herein by this reference.

[0046] The conductive coating (e.g., conductive metal nanoparticle layers) can be applied to a substrate by several techniques, including, printing of conductive inks (e.g., flexographic, screen printing, inkjet, gravure), coating and patterning of e.g., silver halide emulsions which can be reduced to silver particles, coating of conductive nanowire dispersions, and self-assembly of silver nanoparticle dispersions or emulsions.

[0047] The conductive coating as disclosed herein can be used in any electronic device having a touch sensing device. For example these conductive coatings can be used in: electronic displays such as televisions, desktop computer displays, public information displays, educational displays, automotive displays, smart windows; mobile electronic devices such as cell phones, portable computers, tablet computers, wearable electronic devices, such as watches, bands, portions of clothing or other textiles incorporating electronics including touch sensing features; transparent EMI shielding applications, and capacitive sensing applications (such as applications having touch sensing controls). [0048] The conductive coating can contain an EMI shielding material. The conductive coating can include pure metals such as silver (Ag), nickel (Ni), copper (Cu), or similar shielding metal, metal oxides thereof, combinations thereof, and metal alloys including at least one of the foregoing, or metals or metal alloys produced by the Metallurgic Chemical Process (MCP) described in U.S. Pat.

Metal particles of the conductive coating can be nanometer sized, e.g., such as where 90% of the particles can have an equivalent spherical diameter of less than 100 nanometers (nm). The metals of the conductive coating can form a network of interconnected metal traces defining openings on the substrate surface to which it is applied. The surface resistance of the conductive coating can be less than or equal to 1.0 ohm per square (ohm/sq). A conductive coating can have an EMI shielding effectiveness from 30 megahertz (MHz) to 1.5 gigahertz (GHz) as determined per ASTM D4935 of greater than 25 decibel (dB), for example, 30 dB to 80 dB, or, 40 dB to 80 dB. The conductive coating can include carbon based particles arranged in a network, e.g., carbon based particle with a metal mesh. The conductive coating including carbon based particles can be arranged in a regular network. The conductive coating including carbon based particles can be arranged in an irregular network. The carbon based particles can include graphene, carbon nanotubes, or a combination thereof.

[0049] The conductive coating as disclosed herein can be used in any electronic device having a touch sensing device. For example these conductive coatings can be used in: electronic displays such as televisions, desktop computer displays, public information displays, educational displays, automotive displays, smart windows; mobile electronic devices such as cell phones, portable computers, tablet computers, wearable electronic devices, such as watches, bands, portions of clothing or other textiles incorporating electronics including touch sensing features; transparent EMI shielding applications, and capacitive sensing applications (such as applications having touch sensing controls).

[0050] In some aspects the at least one functional layer 500 includes an image forming layer, a conductive layer and/or a touch sensing layer. In certain aspects the image forming layer, conductive layer and/or touch sensing layer is a liquid crystal display.

[0051] The laminate 10 or the article 20 including at least one functional layer 500 thermoformed thereto will thus have functional features corresponding to features provided by the at least one functional layer 500. In some aspects the at least one functional layer 500 may be incorporated into one or more sides of the article 20, as shown in FIGS. 3C and 3D. As noted, these FIGS, are cross sections of the article of FIG. 3A, which is an exemplary electronic device (e.g., mobile phone). Most mobile phones include an image forming layer, a conductive layer and/or a touch sensing layer on the main surface of the phone, but aspects of the present disclosure offer the ability to include these layers on other surfaces (such as one or more sides) of the article 20. As shown in purely exemplary FIG. 3 A, an image forming layer, a conductive layer and/or a touch sensing layer is located on one or more sides of the phone and is visible through the first layer 100, and could display various information on one or more sides of the phone. The electronic device thus includes a primary first surface 25 and at least one second surface 28 extending from the primary first surface 25 at an angle. The laminate 10 including the at least one functional layer 500 overlies both the primary first surface 25 and the at least one second surface 28 such that the at least one functional layer 500 is operable on both the primary first surface 25 and the at least one second surface 28. The at least one second surface 28 can thus display information, such as but not limited to the time 30, lights 40, 50 that flash when the phone rings or when a message is received or the like.

[0052] In addition to the foregoing components, the one or more of the disclosed components (e.g., the first layer 100, the second layer 200, the at least one molded component 300, the at least one adhesive layer 400 and the at least one functional layer 500) can optionally include an effective amount of one or more additional additive materials ordinarily incorporated in articles of this type, with the proviso that the additives are selected so as to not significantly adversely affect the desired properties of the article. Combinations of additives can be used. Such additives can be combined with the other components at a suitable time during the mixing of the components prior to or during the thermoforming process. Exemplary and non-limiting examples of additive materials that can be present in the disclosed molded article include fillers, reinforcing materials, acid scavenger, anti-drip agent, antioxidant, heat stabilizer, antistatic agent, chain extender, colorant (e.g., pigment and/or dye), carbon black, organic dye(s), surface effect additives, radiation stabilizer, de-molding agent, flow promoter, lubricant, mold release agent, plasticizer, quenching agent, flame retardant, hydrolytic stabilizer, ultraviolet (UV) light stabilizer, UV reflecting additive, or any combination thereof. The total amount of additives (other than any impact modifier, filler, or reinforcing agents) is generally 0.01 to 5 wt.%, based on the total weight of the composition. [0053] The reinforcing material can include aramid, carbon, basalt, glass, plastic (e.g., thermoplastic polymer, thermoset polymer), quartz, boron, cellulose, or natural fibers, as well as combinations thereof, such as high stiffness inorganic fibers (e.g., glass, carbon, quartz, boron, and combinations thereof). High stiffness refers to a tensile modulus of greater than or equal to 35 GigaPascals (GPa). For example, the fibers can be formed of liquid crystal polymer, high tenacity polymer (e.g., polypropylene, polyethylene, poly(hexano-6-lactam), poly[imino(l,6- dioxohexamethylene) imnohexamethylene]), as well as combinations thereof. An exemplary fiber filled resin is LEXAN™ resin, commercially available from SABIC Innovative Plastics. Another exemplary fibrous material can include fiber reinforced thermoplastics such as

TM

ULTEM resins, commercially available from SABIC Innovative Plastics). For example, a variety of reinforcement fibers may be used for the outer layers. For example, E-glass, S-glass and various carbon based systems, and combinations thereof, may be employed, e.g., a glass (e.g. E-glass) - carbon hybrid fabric. The outer layer can have a different reinforcing material than the core layer. Certain enclosure applications may need radio frequency transparency. Thus, glass reinforcement can be used in the outer layer in these applications. An exemplary reinforcing material (e.g., for the outer layers) is Tencate CETEX TC925 FST or Tencate CETEX TCI 000 commercially available from Ten Cate Advanced Composites.

[0054] Light stabilizers and/or ultraviolet light (UV) absorbing stabilizers can also be used. Exemplary but non-limiting light stabilizer additives include benzotriazoles such as 2-(2- hydroxy-5- methylphenyl)benzotriazole, 2-(2-hydroxy-5-tert-octylphenyl)-benzotriazole and 2- hydroxy-4-n- octoxy benzophenone, or combinations thereof.

UV light absorbing stabilizers are generally used in amounts of 0.01 to 5 parts by weight, based on 100 parts by weight of the total composition, excluding any filler.

[0055] The laminates 10 and articles 20 can transmit greater than or equal to 50% (e.g.

50 percent transmittance) of incident visible light (e.g., electromagnetic radiation (EMR) having a frequency of 430 THz to 790 THz) through a cross section, for example, 60% to 100%, or, 70%) to 100%). A transparent polymer, substrate, adhesive, and/or material of the article can transmit greater than or equal to 50%> of incident visible light, for example, 75%> to 100%>, or, 90%) to 100%). Percent transmittance for laboratory scale samples can be determined using ASTM D 1003-13 (Standard Test Method for Haze and Luminous Transmittance of Transparent Plastics).

[0056] The laminate 10 and article 20 disclosed herein can successfully pass an industry standard push-out test. Such a push out test can involve applying a load onto a surface (e.g., first surface 1 10 of the first layer 100) while simultaneously resisting this load at an interface of the laminate 10 and the at least one molded component 300 in an attempt to disconnect the at least one molded component 300 and the laminate 10. The applied load can be greater than or equal to 1 lbf (4.4 N), for example 1 lbf to 3 lbf (4.4 N to 13.3 N), or greater than or equal to 5 lbf (22.2 N). The article 20 can successfully pass a thermal cycling test. A thermal cycling test can include subjecting the article 20 to a temperature of -40°C for 60 minutes, then increasing the temperature at a rate of 3-5°C/minute until the article 20 reaches a temperature of 85°C where it is maintained for 60 minutes, followed by decreasing the temperature at a rate of 3-5°C/minute until the article 20 reaches a temperature of -40°C. This cycling can be repeated for 10 to 100 cycles. Once completed, the degree to which the laminate 10 is separated from the at least one molded component 300 is determined. A passing result includes an absence of delamination between the laminate 10 and at least one molded component 300 and at the interface. The article 20 can pass a 90 degree peel test where the at least one molded component 300 is peeled at a 90 degree angle relative to a surface where the laminate 10 is coupled to the at least one molded component 300 with a force of greater than or equal to 5 lbf per linear inch (875 N/m).
