    摘要: Provided are: a fiber-reinforced composite material which is suppressed in morphology variation due to the molding conditions, while having excellent mode I interlaminar fracture toughness and excellent wet heat resistance; an epoxy resin composition for obtaining the fiber-reinforced composite material; and a prepreg which is obtained using the epoxy resin composition. An epoxy resin composition for fiber-reinforced composite materials, which contains at least the following constituent elements [A]-[F], and which is characterized by containing 5-25 parts by mass of constituent element [C] and 2-15 parts by mass of constituent element [E] per 100 parts by mass of the total epoxy resin blended therein. [A] A bifunctional amine type epoxy resin. [B] A tetrafunctional amine type epoxy resin. [C] A bisphenol F type epoxy resin having an epoxy equivalent weight of 450-4,500. [D] An aromatic amine curing agent. [E] A block copolymer having a reactive group that can be reacted with as epoxy resin. [F] Thermoplastic resin particles that are insoluble in an epoxy resin.
