Summary

3D carbon fiber reinforced SiC matrix composites were fabricated by a joint process, which consisted of the slurry infiltration, the organosilicon polymer pyrolysis and the subsequent PCVI (using the source gas system of SiCl4 - CH4 - H2). The deposition rate in the present PCVI was over 2 times as rapid as that in the previous case using MTS - H2 system, though there was little difference in the filled-mass at the saturation point between these two. The strength monotonously increased with increase of pulse-number, which coincided with density variation with pulse-number. The structure of fiber preform had little influence on final residual porosity. In the case of composite fabricated using braid-type preform, the flexural strength at 1473 K in Ar was about 550 MPa, and the strength at 1773 K was over 80 % of that at 1473 K.
