RESIN COMPOSITION FOR FIBER-REINFORCED COMPOSITE MATERIAL AND FIBER-REINFORCED COMPOSITE MATERIAL OBTAINED USING SAME

Provided is a resin composition which satisfactorily infiltrates into reinforcing fibers, has rapid-curing properties, and gives cured formed objects having high heat resistance and which is suitable for use as a matrix resin for fiber-reinforced composite materials excellent in terms of the efficiency of short-time production. The resin composition for fiber-reinforced composite materials is a two-fluid curing type resin composition which is configured of a main ingredient comprising an epoxy resin (A) and an acrylate compound (B) having four or more acryloyl groups in the molecule and a hardener comprising an amine compound (C) represented by general formula (1), wherein the mass ratio of the main ingredient to the hardener is in the range of from 90:10 to 65:35. The resin composition is characterized in that the main ingredient has a viscosity at 25°C, as measured with an E-type viscometer, of 20,000 mPa?s or lower and the hardener has a viscosity at 25°C, as measured with an E-type viscometer, of 800 mPa?s or lower. X-(CH2NH2)n (1) (In formula (1), X represents a C1-16 n-valent organic group and n is 2 or 3.)
