COMPOSITION POUR LA FABRICATION DIRECTE D'UN MATÉRIAU COMPOSITE À MATRICE CÉRAMIQUE
The invention relates to a composition for directly producing a ceramic matrix composite material comprising: a polymer phase comprising at least one thermoplastic elastomer and a low-density polyethylene, the content by volume of the the polymer phase being between 40% and 65% relative to the total volume of the composition; fillers dispersed throughout the polymer phase, the content by volume of the fillers being between 35% and 65% relative to the total volume of the composition and comprising: first fillers composed of particles selected from among particles of silicon carbide (SiC), boron carbide (B4C), silicon nitride (Si3N4), zirconia (ZrO2) and alumina (Al2O3) or from among mixtures of said compounds; and second fillers composed of discontinuous fibrous reinforcements and/or particles that are larger in size than the first fillers, the content by volume of the second fillers being between 0% and 50% relative to the total volume of fillers in the composition; wherein the content by volume of the first filler is between 25% and 40% relative to the total volume of the composition and wherein the content by volume of the second filler is between 5% et 20% relative to the total volume of the composition.
