Document Type and Number:
WIPO Patent Application WO/2022/107709
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a fiber-reinforced resin substrate in which a plurality of resins having differing properties are strongly composited. The present invention is a fiber-reinforced resin substrate obtained by impregnating a thermoplastic resin (A) and a thermoplastic resin (B) into continuous reinforcement fibers, wherein: a thermoplastic resin (A) layer, which comprises the thermoplastic resin (A) and is exposed at one surface, and a thermoplastic resin (B) layer, which comprises the thermoplastic resin (B) and is exposed at the other surface, form a boundary region; at least some of the continuous reinforcement fibers exist in a manner spanning across the boundary region; and both the thermoplastic resin (A) and the thermoplastic resin (B) are a crystalline resin having a melting point of not less than 200°C.
