摘要

Provided is a resin composition for fiber-reinforced composite materials which exhibits excellent flow properties and attains excellent impregnation into fibrous substrates and which can provide a cured product with excellent heat resistance. A resin composition for fiber-reinforced composite materials, characterized by comprising, as the essential components, (A) a poly(glycidyloxyaryl) compound, (B) a polymerizable monomer that consists of an unsaturated carboxylic acid or an anhydride thereof and has a molecular weight of 160 or less, (C) an aromatic vinyl compound or a (meth)acrylic acid ester, and (D) a radical polymerization initiator at an equivalent ratio of the glycidyloxy group of the component (A) to the acid group of the component (B), (glycidyloxy group)/(acid group), of 1/1 to 1/0.48 and at a molar ratio of the component (B) to the component (C), (B)/(C), of 1/0.55 to 1/2.
