    摘要: An epoxy resin composition suitable for use in the fiber reinforced composite material simultaneously exhibiting a high level of tensile strength and a heat resistance is provided. A fiber reinforced composite material produced by using such epoxy resin composition is also provided. An epoxy resin composition comprising at least the following component [A], component [B], and component [C] or [D] wherein cured product obtained by curing the epoxy resin composition has a rubbery state modulus in dynamic viscoelasticity evaluation of 10 MPa or less, and the cured product has a glass transition temperature of at least 95°C; [A] an aromatic epoxy resin having a functionality of at least 3, [B] an aromatic diamine having a substituent at ortho position of each amino group or a cycloalkyldiamine wherein the carbon atom adjacent to the carbon atom bonded to each amino group has a substituent, [C] an aliphatic polyamine having an alkylene glycol structure, [D] a straight chain or branched aliphatic polyamine containing 6 to 12 carbon atoms.

    摘要: The present invention provides a prepreg comprising the following constituent elements (A), (B) and (C), the constituent element (A) being arranged on one surface or both surfaces of a layer containing the constituent elements (B) and (C), and not less than 90 area% of the constituent element (A) existing in the region from the surface of the prepreg to a position up to 20% of the average thickness of said prepreg: (A) epoxy particles having a tan ´ at 10°C of not less than 0.15 and having a three-dimensional cross-linked structure; (B) a first epoxy resin composition; and (C) reinforcing fibers. The present invention provides a prepreg suitable for formation of a fiber reinforced composite material having an excellent stiffness, strength, and damping performance.
