Abstract

La présente invention a pour objet un procédé de fabrication d’un pré-imprégné caractérisé en ce qu’il comprend:i) une étape de fourniture : d’une composition comprenant au moins une résine, et éventuellement une ou plusieurs charge(s) A mélangée(s) avec ladite résine, et d’au moins un renfort textile ; ii) une étape d’application de la composition audit au moins un renfort textile;iii) une étape de saupoudrage d’une ou plusieurs charge(s) B, sur au moins une face F1 dudit au moins un renfort imprégné ;iv) une étape au-cours de laquelle on fait pénétrer la ou lesdites charge(s) B au moins partiellement dans ledit au moins un renfort imprégné;v) une étape de durcissement pour l’obtention dudit pré-imprégné. Figure pour l’abrégé : Fig. 1.The subject of the present invention is a process for manufacturing a prepreg characterized in that it comprises:i) a step of supplying: a composition comprising at least one resin, and optionally one or more filler(s) A mixed with said resin, and at least one textile reinforcement; ii) a step of applying the composition to said at least one textile reinforcement; iii) a step of sprinkling one or more filler(s) B, on at least one face F1 of said at least one impregnated reinforcement; iv) a step during which said filler(s) B are made to penetrate at least partially into said at least one impregnated reinforcement;v) a hardening step to obtain said prepreg.
