FIBER-REINFORCED THERMOPLASTIC RESIN COMPOSITION AND RESIN-METAL COMPOSITE

WIPO Patent Application WO/2024/024653

A1

This fiber-reinforced thermoplastic resin composition comprises a thermoplastic resin composition (T) and a glass fiber (G) having a flat-shaped cross section, wherein: the thermoplastic resin composition (T) contains 100 parts by mass of a styrene-based resin composition (S) having a specific constitution and 0.6-2.0 parts by mass of a crystal nucleating agent (C); and the content of the glass fiber (G) is 33.0-65.0 mass% with respect to the total amount of the thermoplastic resin composition (T) and the glass fiber (G). Moreover, this resin-metal composite comprises: a resin member composed of a reinforced thermoplastic resin composition containing a thermoplastic resin composition (T2) and a glass filler (G2); and a metal member, wherein the difference between the linear expansion coefficient of the resin member in TD and the linear expansion coefficient of the metal member is at most 6.0×10-5/ºC, and the bending fracture strain of a parallel flow weld test piece composed of the reinforced thermoplastic resin composition is at least 1.15%.
