ABSTRACT:
A fiber reinforced ceramic matrix composite is disclosed which comprises a ceramic matrix and a fiber preform integrally assembled therein, the fiber preform comprising a braided fabric derivable from braiding a yarn which is composed of a plurality of fiber bundles formed of a plurality of monofilaments bundled together, the braided fabric being present in a volume fraction of fiber (Vf) of 10 to 40% by volume based on the total volume of the ceramic matrix composite. The yarns (fiber bundles) may preferably be disposed in oblique relation to each other. Initial matrix cracking strength, crack propagation resistance and fracture energy are greatly increased. Fiber preforms having a complicated shape can be easily obtained.
