Rapid densification multiphase matrix of silicon carbide ceramic-based composite material and preparation method of rapid densification multiphase matrix

The invention discloses a rapid densification multiphase matrix of a silicon carbide ceramic-based composite material and a preparation method of the rapid densification multiphase matrix. According to the preparation method, the technical main line of preparing the multi-phase SiC ceramic composite material through cooperation of the precursor impregnation and pyrolysis process and the reaction melting siliconizing process is adopted, the microstructure of the composite material prepared through the mixing process is optimized and improved by regulating the introduction sequence of the reaction activated carbon and the ceramic matrix prepared through the precursor impregnation and pyrolysis process, and the mechanical property of the material is effectively improved. Compared with a ceramic-based composite material prepared by an existing melt siliconizing process, the method has the advantage that the mechanical property is better. Meanwhile, compared with a ceramic precursor impregnation cracking process,
