METHOD FOR FABRICATING CERAMIC MATRIX COMPOSITE

摘要

A method for fabricating a CMC (Ceramic Matrix Composite) article, comprising: performing a CVI (Chemical Vapor Infiltration) treatment (5) for forming a SiC matrix layer on the surface of a woven fabric; performing a machining process (6), after the CVI treatment (5), for machining the woven fabric; and performing a PIP (Polymer Impregnation and Pyrolysis) treatment (7), after the machining process (6), for impregnating an organic silicon polymer as a base material into voids in the matrix layer and pyrolyzing the organic silicon polymer. By this method, the throughput o f CMC articles can be preferably increased. The throughput may be further increase d by performing a slurry impregnation treatment (13) before or after the PIP treatment (7), in which slurried SiC is impregnated into the voids in the matrix layer.
