Abstract

Procédé amélioré de réalisation d'une préforme fibreuse consolidée Procédé de réalisation d'une préforme fibreuse consolidée destinée à la fabrication d'une pièce en matériau composite, comprenant les étapes de :- mise en forme d'une texture fibreuse par imprégnation par un matériau fugace ou fugitif,- mise en place de la préforme fibreuse pré-consolidée dans un moule et injection d’une mousse polyuréthane (50) dans le moule pour enrober la préforme fibreuse (40) de mousse polyuréthane,- démoulage, après réticulation de la mousse polyuréthane, de la préforme fibreuse (40) enrobée de ladite mousse,- imprégnation de la mousse polyuréthane par un précurseur de carbone,- traitement thermique de la préforme fibreuse (40) de manière à former une mousse carbone à partir du précurseur de carbone autour de la préforme fibreuse, et à éliminer la mousse pulyuréthane (50) et le matériau fugace ou fugitif présent dans la préforme fibreuse,- consolidation par infiltration chimique en phase gazeuse de la préforme fibreuse. Figure pour l’abrégé : Fig. 5.Improved method for producing a consolidated fibrous preform Method for producing a consolidated fibrous preform intended for the manufacture of a part made of composite material, comprising the steps of:- shaping a fibrous texture by impregnation with a material fleeting or fugitive, - placement of the pre-consolidated fiber preform in a mold and injection of a polyurethane foam (50) into the mold to coat the fiber preform (40) with polyurethane foam, - demoulding, after crosslinking of the polyurethane foam, of the fiber preform (40) coated with said foam,- impregnation of the polyurethane foam with a carbon precursor,- heat treatment of the fiber preform (40) so as to form a carbon foam from the carbon precursor around the fibrous preform, and removing the polyurethane foam (50) and the fugitive or fugitive material present in the fibrous preform, - consolidation by chemical infiltration in the gaseous phase of the fibrous preform.
