The present invention provides a resin composition suitable for use as a fiber-reinforced composite material, which exhibits good impregnation with reinforcing fibers, has rapid curability, and has high heat resistance of a molded product. The resin composition for fiber-reinforced composite materials of the present invention is a two-component curable resin comprising a main agent and a curing agent and having a mass ratio of the main agent and the curing agent in the range of 85:15 to 65:35. A composition in which the above-mentioned main agent contains an epoxy resin (A) and a (meth)acrylate compound (B) having three or more (meth)acryloyl groups in one molecule, and the above-mentioned curing agent contains the following general formula ( The amine compound (C) represented by 1) contains 75 to 100 mass % of bisphenol A-type epoxy resin in the epoxy resin (A), the viscosity of the main agent is 10000 mPa·s or less, and the viscosity of the curing agent is 800mPa·s or less. X-(CH 2 NH 2 ) n (1) (in the formula, X represents an n-valent organic group having 1 to 16 carbon atoms, and n represents 2 or 3). |
