Abstract:
An epoxy resin composition produces a cured product having improved elastic modulus and improved nominal strain at compressive fracture. The epoxy resin composition is a fiber-reinforced composite material having excellent compression strength and interlayer toughness. The epoxy resin composition contains at least the following constituent components [A], [B] and [C]. [A] A specific ortho type epoxy resin. [B] At least one component selected from the group consisting of: thermoplastic resins that are compatible with the epoxy resin [A]; and core-shell type polymers. [C] An amine curing agent.

Claim (Index 14):
An epoxy resin composition comprising at least components [A], [B], and [C]:\n [A] an epoxy resin as represented by Formula (1) or an epoxy resin as represented by Formula (2), [A] accounting for 15 to 70 parts by mass relative to the total epoxy resin quantity, which accounts for 100 parts by mass, when [A] is an epoxy resin as represented by Formula (1): wherein each R 1  in Formula (1) and Formula (2) is a hydrogen atom or a methyl group, the plurality of R 1 's being not necessarily identical to each other; R 2  to R 6  are each a substituent group selected from the group consisting of an alkyl group containing 1 to 10 carbon atoms, a cycloalkyl group containing 6 to 15 carbon atoms, an aryl group containing 6 to 18 carbon atoms, a hydrogen atom, and a halogen atom; each k, which denotes the number of substituents, is an integer of 0 to 4, the k's being not necessarily identical to each other; n, which denotes the number of repeating units, is an integer of 0 or more; X, which denotes a linking group, is one selected from the group consisting of \u2014C(Y)(Z)\u2014 (wherein Y and Z are each an alkyl group containing 1 to 10 carbon atoms, a cycloalkyl group containing 6 to 15 carbon atoms, an aryl group containing 6 to 18 carbon atoms, a hydrogen atom, or a halogen atom, Y and Z being either identical to or different from each other), \u2014C(\u2550O)NH\u2014, \u2014C(\u2550O)O\u2014, \u2014S(\u2550O) 2 \u2014, \u2014C(\u2550O)\u2014, \u2014O\u2014, \u2014S\u2014, and \u2014 (no atoms); [B] at least one component selected from the group consisting of a thermoplastic resins compatible with the epoxy resin [A], and core-shell polymers; and [C] amine curing agent.
