Abstract

Procédé de fabrication d’une pièce creuse en matériau composite à matrice métallique ou céramique renforcée avec des fibres courtes Un procédé de fabrication d’une pièce creuse en matériau composite à matrice céramique ou métallique comprenant les étapes suivantes :- préparation d’une matière première (30) comprenant au moins des fibres courtes et une charge précurseur de matrice céramique ou de matrice métallique,- positionnement d’un noyau sacrificiel (10) dans une cavité de moulage (23) d’un outillage d’injection (20), la cavité de moulage présentant des dimensions supérieures aux dimensions du noyau sacrificiel, - mise en forme de la matière première (30) par moulage par injection de ladite matière première dans l’espace libre (230) entre le noyau sacrificiel (10) et une paroi interne de la cavité de moulage de manière à obtenir une pièce verte comprenant le noyau sacrificiel et la matière première mise en forme,- extraction de la pièce verte de l’outillage d’injection (20),- densification de la matière première (30) par frittage flash de la pièce verte de manière à transformer la charge en matrice céramique ou en matrice métallique,- retrait ou élimination du noyau sacrificiel (10) de manière à obtenir une pièce creuse en matériau composite à matrice céramique ou métallique.
