PURPOSE: To obtain lightweight prepreg for molding an FRP product, having a low modulus of elasticity, excellent moldability and heat characteristics by impregnating an epoxy resin composition containing a polyepoxy compound and a curing agent into reinforcing fibers composed of filament carbon fibers. CONSTITUTION: This prepreg is obtained by impregnating an epoxy resin composition containing (A) a polyepoxy compound containing at least two or more epoxy groups in one molecule (e.g. bisphenol A type epoxy resin), (B) a curing agent (preferably dicyandiamide) and (C) a curing promotor into (D) reinforcing fibers composed of filament carbon fibers having 0.4-7ton/mm<2> modulus of elasticity and <=11μm average diameter. |
