The present invention relates to an epoxy resin composition which comprises a phosphorus-containing modified epoxy resin (A) consisting of a compound (a) represented by Formula (a); a novolak epoxy resin (B); a hardener (C) for epoxy resins; and a metal hydroxide (D), wherein the content in mass% of the phosphorus-containing modified epoxy resin (A), C A , and the content in mass% of the metal hydroxide (D), C D , relative to the total amount of the epoxy resin composition, satisfy the following Formulas (1), (2), and (3) : (1) 2.5C A +C D ‰¥45; (2) 6‰¤C A ‰¤40; and (3) 3‰¤C D ‰¤30. This epoxy resin composition can give a composite material which has excellent flame retardancy even when neither a halogenated flame retardant, nor red phosphorus, nor a phosphoric acid ester is contained therein. According to the invention, it is also possible to provide a prepreg and a fiber-reinforced composite material obtained using the prepreg. |
