Epoxy resin composition, prepreg, fiber reinforced composite material

摘要: It is an object of the present invention to improve drawbacks in conventional technology and provide a fiber-reinforced composite material having both excellent static strength property impact resistance, epoxy resin composition for obtaining material. More particularly, it that gives cured high elastic modulus, heat plastic deformation capacity toughness. The containing following [A] [D], prepreg obtained by impregnating fiber substrate with composition, curing tubular body thereof. 10 60 parts weight amine type resin, [B] 40 90 bisphenol-type [C] 1 dicyandiamide or derivative thereof, [D] at least one block copolymer selected from group consisting S-B-M, B-M M-B-M.
