Resin composition for fiber reinforced composite material, resin composition impregnated reinforced fiber for fiber reinforced composite material, and fiber reinforced composite material

摘要

PROBLEM TO BE SOLVED: To provide a resin composition for fiber reinforced composite material satisfying rapid harden ability, low viscosity, high thermostability, high toughness and low shrinkage on curing concurrently.SOLUTION: A resin composition for fiber reinforced composite material contains at least one kind chosen from a group consisting of optical acid generant (C) generating acid by irradiation with active energy line, heat acid generant (D) generating acid by heating and other epoxy curing agents (E), and cross-linked cyclic alicyclic di-epoxy compound (A) shown with a formula (1) and/or bridged alicyclic di-epoxy compound.
