    摘要： Provided are a fiber-reinforced composite material excellent in heat resistance and strength properties, an epoxy resin composition to obtain the fiber-reinforced composite material, and a prepreg obtained by using the epoxy resin composition. Further provided are a fiber-reinforced composite material having less volatile matters during the curing time, and having excellent heat resistance and strength properties, an epoxy resin composition to obtain the fiber-reinforced composite material, and a prepreg obtained by using the epoxy resin composition. Provided are: an epoxy resin composition for a fiber-reinforced composite material, comprising an amine type epoxy resin [A], an aromatic amine curing agent [B], and a block copolymer [C] having a reactive group capable of reacting with an epoxy resin; a prepreg obtained by impregnating a reinforced fiber with the epoxy resin composition; and a fiber-reinforced composite material obtained by curing the prepreg. Further provided are: an epoxy resin composition comprising an epoxy resin [A] having two or more of four- or more-membered ring structures, and having either one of a glycidyl amino group directly bonded to the ring structure or a glycidyl ether group directly bonded to the ring structure, epoxy resin [B] having three or more of functional groups, a curing agent [C], and an elastomer component [D]; a prepreg obtained by impregnating a reinforced fiber with the epoxy resin composition; and a fiber-reinforced composite material obtained by curing the prepreg.
