Beschreibung
Zusammenfassung:	A method for producing a fiber-reinforced composite material having high mechanical properties and high heat resistance, and allowing the use of a gypsum die in primary curing, wherein a fiber-reinforced prepreg, obtained by impregnating reinforcing fibers with an epoxy resin composition comprising a triphenylmethane-type epoxy resin, N,N,N',N'-tetraglycidyldiaminodiphenylmethane (B) and diaminodiphenylsulfone (C), is subjected to primary curing at 110-130°C, and then to secondary curing at a temperature which is at least as high as the primary curing temperature.
