The invention provides a prepreg having high storage stability and serving suitably for producing components, such as structural members and interior members of aircraft and structural members of aircraft engines, that require high heat resistance under high temperature and high humidity conditions, where the prepreg exhibits good physical properties and good combustion properties. The prepreg is produced by impregnating component [A] with an epoxy resin composition containing components [B] to [D], wherein component [A] in the prepreg accounts for 50 mass % or more, where [A] is a carbon fiber, [B] is an epoxy resin, [C] is a fluorene type curing agent having a maximum particle size of 100 μm or less, and [D] is a thermoplastic resin. |
