Abstract
The present invention has an object to provide a resin composition for fiber-reinforced composite materials that excels in rapid curability without impairing low viscosity and heat resistance. A two-component curable resin for fiber-reinforced composite materials is provided, which is configured of a base material including an epoxy resin (A) and a curing agent including an amine compound (B) selected from either norbornane diamine or triethylenetetramine and a phenol compound (C), and in which a mass ratio of the base material to the curing agent is within the range of from 90:10 to 70:30, and the phenol compound (C) includes a phenol compound including two or more phenolic hydroxyl groups and is contained at 5% by weight to 35% by weight in the curing agent. A fiber-reinforced composite material is obtained by mixing reinforcing fibers in the resin composition for fiber-reinforced composite materials.
