Abstract

Abstract Translated from French Une mince couche adhérente intermédiaire réfractaire à structure en feuillets est déposée de façon orientée sur les fibres du renfort par infiltration chimique en phase gazeuse, cette couche intermédiaire ayant un allongement à la rupture supérieur à celui de la matrice et ayant une épaisseur comprise entre 0,2 et 3 microns; le matériau de la couche intermédiaire peut être du pyrocarbone laminaire ou du nitrure de bore; la matrice céramique est ensuite déposée par infiltration, de préférence infiltration chimique en phase gazeuse, au sein de la porosité du renfort. A thin refractory intermediate adherent layer with a sheet structure is deposited in an oriented manner on the fibers of the reinforcement by chemical infiltration in the gas phase, this intermediate layer having an elongation at break greater than that of the matrix and having a thickness of between 0, 2 and 3 microns; the material of the intermediate layer can be laminar pyrocarbon or boron nitride; the ceramic matrix is then deposited by infiltration, preferably chemical infiltration in the gas phase, within the porosity of the reinforcement.
