Provided is a resin composition that exhibits satisfactory impregnability into reinforcing fibers, while having rapid curability, and that is suitable for fiber-reinforced composite materials producing molded articles having high heat resistance. A two-pack resin composition for fiber-reinforced composite materials is configured of a base material including an epoxy resin (A) and a (meth)acrylate compound (B) having three or more (meth) acryloyl groups in a molecule, and a curing agent including an amine compound (C) represented by the following general formula (1), a mass ratio of the base material to the curing agent being within the range of from 35:15 to 65:35, Wherein the epoxy resin (A) includes 75% by mass to 100% by mass of a bisphenol A epoxy resin; the base material has a viscosity of 10,000 mPa·s or less; and the curing agent has a viscosity of 800 mPa·s or less.
