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 component [C] contains a compound represented by a particular formula (a), and a prepreg and a fiber reinforced composite material using the same.
