Title:
MULTILAYER STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2013/065692
Kind Code:
A1
Abstract:
This multilayer structure (4) is a product obtained by laminating a fiber sheet (2) and a thermoplastic resin film (3) on at least one principal surface of a hollow plate-shaped body (1) made of a thermoplastic resin. Even when the multilayer structure (4) is bent, no or few protuberant wrinkles (6) due to buckling or flexing are formed in the inside. Therefore, the multilayer structure (4) is less susceptible to strength degradation, and thus can satisfy both bending rigidity and bending strength while keeping the light weight. The fiber sheet (2) is preferably a multiaxial fiber sheet and/or a woven fabric. It is preferable that the lamination is conducted by heat lamination with an adhesive film interposed.
