Title (EN) METHOD FOR PRODUCING A CONSOLIDATED FIBROUS PREFORM
(FR) PROCÉDÉ DE RÉALISATION D'UNE PRÉFORME FIBREUSE CONSOLIDÉE
Abstract:
(EN) A 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 (10) in a heated metal mould (20), the texture being pre-impregnated with a transient or transitory material (30), or shaping a fibrous texture in a metal mould and injecting a transient or transitory material into the fibrous texture held in shape in the metal mould, - cooling the mould, - removing the set fibrous preform from the mould, - coating the fibrous preform with a slip containing a powder of ceramic or carbon particles, - heat-treating the coated fibrous preform so as to form a porous shell around the fibrous preform by consolidation of the slip and so as to remove the transient or transitory material present in the fibrous preform, - consolidating the fibrous preform by gas-phase chemical infiltration.
(FR) Un 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 (10) dans un moule métallique chauffé (20), la texture étant imprégnée préalablement d'un matériau fugace ou fugitif (30), ou mise en forme d'une texture fibreuse dans un moule métallique et injection d'un matériau fugace ou fugitif dans la texture fibreuse maintenue en forme dans le moule métallique, - refroidissement du moule, - démoulage de la préforme fibreuse figée, - enrobage de la préforme fibreuse avec une barbotine contenant une poudre de particules céramique ou carbone, - traitement thermique de la préforme fibreuse enrobée de manière à former une carapace poreuse autour de la préforme fibreuse par consolidation de la barbotine et à éliminer le matériau fugace ou fugitif présent dans la préforme fibreuse, - consolidation par infiltration chimique en phase gazeuse de la préforme fibreuse.
