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. L'invention porte sur un procédé de fabrication d'un matériau composite renforcé par des fibres avec de bonnes propriétés mécaniques et une résistance élevée à la chaleur, de telle sorte qu'un moule en plâtre puisse être utilisé pour un durcissement initial. Un préimprégné renforcé par des fibres, obtenu par imprégnation de fibres renforcées par une composition de résine époxy qui contient une résine époxy de type triphénylméthane (A), du N, N, N', N'-tétraglycidyl diaminodiphénylméthane (B), et de la diaminodiphénylsulfone (C), subit un durcissement initial à 110-130°C et en plus subit un second durcissement à une température non inférieure à la température du durcissement initiale.
