Two-pack epoxy resin composition for fiber-reinforced composite materials, and fiber-reinforced composite material

Abstract

A two-pack epoxy resin composition for a fiber-reinforced composite material, which composition includes the following components [A] to [D], and in which the mass compounding ratio of component [A] and component [B] is 5:95-50:50, there is provided a fiber-reinforced composite material which has exceptional workability during resin preparation, exceptional stability of viscosity of the resin composition at low temperatures, and exceptional impregnation properties such that low viscosity is maintained during injection into reinforcing fibers, and which cures with a short time during molding, and has high dimensional stability and exceptional heat resistance.
