Summary

Dense SiC matrix composites reinforced with both Hi-Nicalon plain weave and SCS-9 unidirectional sheet were fabricated. The SiC matrix was consolidated by slurry impregnation and a subsequent reaction-sintering process. A two-step slurry impregnation was applied. The first matrix slurry containing a ceramic precursor and a resin was impregnated inside the yarn, and the surrounding matrix was formed by pressure casting of the second matrix slurry containing SiC and carbon powders. The density of the reaction-sintered composite was above 3.0 g/cm3. The initial matrix cracking strength by three-point bending test at room temperature was 465 MPa, and its fracture behavior was not catastrophic.
