RESIN COMPOSITION FOR FIBER-REINFORCED COMPOSITE MATERIAL, CURED OBJECT OBTAINED THEREFROM, FIBER-REINFORCED COMPOSITE MATERIAL, FIBER-REINFORCED MOLDED RESIN, AND PROCESS FOR PRODUCING SAME

摘要

The present invention provides a resin composition for a fiber-reinforced composite material, which has excellent fluidity at low temperature and which produces a cured product having excellent mechanical strength, and also provides a cured product thereof, a fiber-reinforced composite material, a fiber-reinforced resin molding having excellent heat resistance, and a process for producing a fiber-reinforced resin molding with good productivity. A resin composition for a fiber-reinforced composite material contains, as essential components, an epoxy resin (A), an acid group-containing radical polymerizable monomer (B), a radical polymerization initiator (C), and an amine-based curing agent (D) for an epoxy resin, and has a viscosity of 500 mPa·s or less at 50°C measured with an E-type viscometer. The composition is impregnated into reinforcing fibers and cured.
