摘要: A process for manufacturing a ceramic matrix composite part, includes infiltrating a fibrous structure including a powder composition with a melt infiltration composition including at least silicon in order to form a ceramic matrix in the porosity of the fibrous structure, the powder composition including at least silicon carbide particles, wherein the silicon carbide particles have a bimodal size distribution with a first set of silicon carbide particles having a first average size and a second set of silicon carbide particles having a second average size smaller than the first average size, the number of particles in the first set being greater than the number of particles in the second set.

摘要: 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.
