Title:
BASE MATERIAL FOR FIBER-REINFORCED PLASTIC MOLDED BODIES, METHOD FOR PRODUCING FIBER-REINFORCED PLASTIC MOLDED BODY, AND FIBER-REINFORCED PLASTIC MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2019/073707
Kind Code:
A1
Abstract:
Provided are: a fiber-reinforced plastic molded body which has excellent appearance, solvent resistance, water resistance and heat resistance; a base material for fiber-reinforced plastic molded bodies, which enables the achievement of the above-described fiber-reinforced plastic molded body by an easy molding process; and a method for producing a fiber-reinforced plastic molded body. A base material for fiber-reinforced plastic molded bodies, which comprises: a fiber-reinforced layer that contains reinforcing fibers and a matrix thermoplastic resin; a surface layer that contains a thermoplastic resin; and an isolation layer which is arranged between the fiber-reinforced layer and the surface layer, and which is composed of a nonwoven fabric that contains heat-resistant thermoplastic resin fibers that have a higher melting temperature than the thermoplastic resin contained in the surface layer. This base material for fiber-reinforced plastic molded bodies is configured such that the ratio of the volume per square meter W1 of the surface layer to the volume per square meter W2 of the isolation layer, namely W1/W2 is from 1.3/1 to 3.5/1. A method for producing a fiber-reinforced plastic molded body, which comprises a process of laminating the above-described layers and molding the layers under heat and pressure; and a fiber-reinforced plastic molded body which is produced using the above-described base material, or which is obtained by the above-described production method.
