Abstract
A part is made of a composite material having an alumina matrix by impregnating a fiber texture with a fluid composition containing a liquid precursor of alumina, a thermoplastic resin, and a suspension of alumina powder, and subsequently convening the precursor into alumina. Additional solid fillers may be added to the impregnation composition. The impregnated fiber texture is preferably made by draping and molding plies that are pre-impregnated with said composition.
