Silicon carbide fiber reinforced silicon carbide composite material
The present invention provides a silicon carbide fiber reinforced silicon carbide composite material, which is a composite material of SiC fibers and SiC ceramics with improved toughness and can be produced with high yield by relatively simple steps without complex steps such as a step of oxidation-resistant coating or an advanced interface control step. The silicon carbide composite material comprises a multiphase matrix and silicon carbide fibers disposed in the matrix, the matrix containing a silicon carbide phase and a phase that includes a substance of low reactivity with respect to silicon carbide. It can be obtained by steps suitable for mass production and ensures greatly improved fracture toughness while maintaining the excellent properties of SiC ceramics.
