Abstract

A method of fabricating a composite material part includes placing a fiber texture in a mold including in its bottom portion a porous material part on which a first face of the texture rests, injecting a liquid under pressure into the fiber texture, the liquid containing a powder of refractory ceramic particles, and draining through the porous material part the liquid that has passed through the fiber texture, while retaining the powder of refractory ceramic particles inside said texture by the porous material part. A perforated rigid element is interposed between the bottom of the mold and the porous material part.
