Abstract

Procédé de fabrication d’une pièce en matériau composite par drapage de textures fibreuses Procédé (200) de fabrication d’une pièce en matériau composite comprenant au moins : la formation d’une préforme fibreuse (201) de la pièce à obtenir par dépôt d’une pluralité de textures fibreuses imprégnées d’une première résine liante par drapage des textures fibreuses, le dépôt étant effectué sur un textile d’arrachage comprenant une deuxième résine liante présente en une teneur en poids sec comprise entre 3 g/m² et 15 g/m² et étant réalisé à une température de travail permettant l’adhésion des première et deuxième résines liantes ;l’élimination des première et deuxième résines liantes (202) dans la préforme ainsi formée, etla formation d’une matrice (203) dans la porosité de la préforme fibreuse après l’élimination des première et deuxième résines liantes, et l’élimination du textile d’arrachage afin d’obtenir la pièce en matériau composite. Figure pour l’abrégé : Fig. 2Method for manufacturing a part made of composite material by draping fibrous textures Method (200) for manufacturing a part made of composite material comprising at least: the formation of a fibrous preform (201) of the part to be obtained by deposition of 'a plurality of fibrous textures impregnated with a first binder resin by draping the fibrous textures, the deposition being carried out on a tear-off textile comprising a second binder resin present in a dry weight content of between 3 g/m² and 15 g /m² and being carried out at a working temperature allowing the adhesion of the first and second binder resins; the elimination of the first and second binder resins (202) in the preform thus formed, and the formation of a matrix (203) in the porosity of the fibrous preform after the elimination of the first and second binder resins, and the elimination of the tear textile in order to obtain the composite material part.
