METHOD FOR PRODUCING A PART MADE OF SICF/SIC COMPOSITE MATERIAL FROM A COLLOIDAL SUSPENSION

摘要

the invention relates to a process for the manufacture of a ceramic matrix composite material, room type, which comprises a sicf / sic fibre reinforced sic matrix densified by a process comprising: 3(a) implementation of the contact of a preform to produce a colloidal dispersion piece, the preform consisting of the colloidal dispersion of sic fibers and sic particle size of submicron sized or nano dispersed in at least one solvent and a meadow when liquid ceramic sic.(b) an electrophoretic particle, infiltration of sic and sic ceramic precursor contained in the colloidal dispersion in the preform.(c) a density of the preform infiltrated by heat treatment to decompose the precursor of sic ceramic, ceramic, which is ceramic matrix composite part.
