Abstract:
Provided are an epoxy resin composition for manufacturing a fiber reinforced composite material having excellent curability allowing for curing in a short time, and excellent storage stability and heat resistance, and a prepreg and a fiber reinforced composite material using the same. The epoxy resin composition includes at least an epoxy resin [A], a curing agent [B] having an exothermic onset temperature higher than the exothermic onset temperature of a component [C], as measured by a differential scanning calorimeter, and the compound [C] represented by formula (a), in which the compounding ratio for the components satisfies equations (1) and (2), and a prepreg and a fiber reinforced composite material using the same. Equation (1): 0.5 (moles of active hydrogen included in component [B]+moles of active hydrogen included in component [C])/moles of epoxy groups in component [A]≤1.5; Equation (2) 0.02≤moles of component [C]/moles of component [B]≤5.0. In formula (a), X is chosen from C═O, S═O and O═P—OH, and R1 to R4 are at least one atom or group selected from the group consisting of a hydrogen atom, an aliphatic hydrocarbon group having 1 to 4 carbon atoms, an alicyclic hydrocarbon group having 4 or fewer carbon atoms, and a halogen atom.

Claim (Index 10):
An epoxy resin composition as set forth in  claim 1 , further comprising a component [D] as described below:\n [D] thermoplastic resin.
