Abstract
Official abstract text for this publication.
A method of fabricating a part out of ceramic matrix composite material, the method including infiltrating a fiber preform with a molten composition including a majority by weight of silicon, the fiber preform including silicon carbide fibers, silicon carbide powder being present in the pores of said preform, a mean size of silicon carbide crystallites in the powder being less than the mean size of the silicon carbide crystallites in the fibers, a ceramic matrix being formed in the pores of the fiber preform during the infiltration so as to obtain the part made of composite material.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of fabricating a part out of ceramic matrix composite material, the method comprising: infiltrating a fiber preform with a molten composition comprising a majority by weight of silicon, the fiber preform comprising silicon carbide fibers, silicon carbide powder being present in the pores of said preform, a mean size of silicon carbide crystallites in the powder being less than the mean size of the silicon carbide crystallites in the fibers, a ceramic matrix being formed in the pores of the fiber preform during the infiltration so as to obtain the part made of composite material, wherein prior to infiltration, the fiber preform presents a consolidation phase comprising silicon carbide, the mean size of the silicon carbide crystallites in the powder being less than or equal to 80% of the mean size of the silicon carbide crystallites in the consolidation phase. 2. A method according to claim 1 , wherein the mean size of the silicon carbide crystallites in the powder is less than or equal to 80% of the mean size of the silicon carbide crystallites in the fibers. 3. A method according to claim 1 , wherein an interphase is formed on the fibers before the infiltration step. 4. A method according to claim 3 , wherein the interphase is formed by at least one layer of the following materials: pyrolytic carbon, boron-doped carbon, or boron nitride. 5. A method according to claim 1 , wherein the fiber preform is made as a single piece by three-dimensional weaving or from a plurality of two-dimensional fiber plies.
