    摘要： An organic silicon polymer is infiltrated and charged into gaps in a matrix phase of a formed fiber fabric, and its airtightness is increased by (a) CVI infiltration process 2 for forming the SiC matrix phase on the surface of the fiber fabric formed, (b) pressurized infiltration process 4 for pressurizing the organic silicon polymer in the direction operating pressure is applied to the fiber fabric during use and infiltrating the organic silicon polymer into gaps in the aforementioned matrix phase, and (c) heating process 5 for heating the infiltrated fiber fabric at a high temperature. Thus, airtightness can be increased quickly, and fired work can be applied practically even to thrust chambers etc.

    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 of CMC articles can be preferably increased. The throughput may be further increased 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.
