The process comprises the steps of forming a fibrous reinforcement with silicium carbide fibers, forming on the fibers an intermediate coating designed to constitute an interface between the fibers and a matrix, and forming a matrix in ceramic material within the residual porosity of the fibrous reinforcement. In a step prior to the formation of the intermediate coating, a treatment is carried out by the chemical route for the elimination of the silica present on the surface of the silicium carbide fibers. |
