Abstract

Procédé de fabrication d’une pièce en matériau composite par injection d’une barbotine chargée dans une texture fibreuse L’invention décrit un procédé de fabrication d’une pièce en matériau composite comprenant le placement d’une texture fibreuse (10) dans un moule (110) comportant dans sa partie inférieure une strate de filtration (130) sur laquelle repose la texture fibreuse (10) et comportant une portion perforée (150) interposée entre la strate de filtration et le fond du moule, l’injection sous pression d’un liquide contenant une poudre de particules céramiques réfractaires dans la texture fibreuse, le drainage par la strate de filtration du liquide ayant traversé la texture fibreuse et la rétention de la poudre de particules céramiques réfractaires à l’intérieur de ladite texture fibreuse par ladite strate de filtration. Un élément de distribution (140) est interposé entre la strate de filtration (130) et la portion perforée (150). Figure pour l’abrégé : Fig. 1Method of manufacturing a part made of composite material by injecting a slip loaded into a fibrous texture. The invention describes a method of manufacturing a part of composite material comprising the placement of a fibrous texture (10) in a mold (110) comprising in its lower part a filtration layer (130) on which the fibrous texture (10) rests and comprising a perforated portion (150) interposed between the filtration layer and the bottom of the mold, injection under pressure d 'a liquid containing a powder of refractory ceramic particles in the fibrous texture, the drainage by the filtration stratum of the liquid having passed through the fibrous texture and the retention of the powder of refractory ceramic particles inside said fibrous texture by said stratum filtration. A distribution element (140) is interposed between the filtration stratum (130) and the perforated portion (150). Figure for abstract: Fig. 1
