Continuous fiber-reinforced SiC matrix composites with different reinforcement geometries have been successfully fabricated by a chemical vapor infiltration technique. The density, pore distribution and microstructure development of the resulting composites at various processing stages were characterized. The mechanical properties, including tensile, flexural, fracture toughness, environmental resistance and deformation mechanisms were evaluated. The results indicate that a ceramic composite with high strength, fracture toughness and good environmental resistance can be produced through the optimization of preform geometry and CVI parameters. 13 refs.
