Abstract
The present invention provides a resin composition for a fiber-reinforced composite material, which has excellent fluidity and impregnation into a fiber base material and which produces a cured product having excellent heat resistance. A resin composition for a fiber-reinforced composite material contains, as essential components, a poly(glycidyloxyaryl) compound (A), a polymerizable monomer (B) which is an unsaturated carboxylic acid or an anhydride thereof and has a molecular weight of 160 or less, an aromatic vinyl compound or a (meth)acrylate (C), and a radical polymerization initiator (D), wherein an equivalent ratio [glycidyloxy group/acid group] of a glycidyloxy group in the component (A) to an acid group in the component (B) is 1/1 to 1/0.48, and a molar ratio [(B)/(C)] of the component (B) to the component (C) is in the range of 1/0.55 to 1/2.
