FIBER-REINFORCED RESIN COMPOSITE SHEET, FIBER-REINFORCED RESIN COMPOSITE MATERIAL, AND MOLDED RESIN ARTICLE INCLUDING SAME

WIPO Patent Application WO/2021/215162

A1

Provided is a fiber-reinforced resin composite sheet that has excellent flame retardant properties, that has favorable moldability, and that has sufficient tensile strength in high temperature conditions. The fiber-reinforced resin composite sheet includes a flame-retardant resin film which is made from a thermoplastic resin composition that has a glass transition temperature Tg of not less than 90°C, and a plurality of reinforcement fibers which are from an opened reinforcement fiber bundle and which are laminated in the flame-retardant resin film so as to be aligned along the same direction. The flammability category of the flame-retardant resin film as determined by the UL94VTM flammability test according to the ASTM D4804 standard is VTM-0. The volume content Vf of the reinforcement fibers is 30-65%. The thickness of the fiber-reinforced resin composite sheet is 20-100 μm. The flammability category of the fiber-reinforced resin composite sheet as determined by the UL94-5V flammability test according to the ASTM D5048 standard is 5V-A or 5V-B.
