Abstract
Procédé de formation d'une pièce en composite à matrice céramique, par exemple une pièce de turbine, comprenant les étapes suivantes : (a) appliquer un revêtement de fibre sur un faisceau de fibres (10) par dépôt chimique en phase vapeur, (b) tirer le faisceau de fibres (10) à travers une suspension aqueuse composée de liants haute et basse température, de poudre de carbure de silicium, de noir de carbone et d'eau afin de former ainsi une bande préimprégnée, et (c) enrouler la bande préimprégnée sur un tambour (18).
