Ceramic matrix composite material employing silicon alkyne-modified SiBCN as precursor and preparation method of ceramic matrix composite material
The invention relates to a ceramic matrix composite material employing silicon alkyne-modified SiBCN as a precursor and a preparation method of the ceramic matrix composite material, and belongs to the technical field of ceramic materials. Polysilylacetylene is introduced into an SiBCN precursor in a molecular level to prepare a silicon alkyne-modified SiBCN precursor, so that the compactness of the composite material ceramic matrix can be effectively improved; the ceramic yield is increased; and meanwhile, a split product can have excellent high-temperature oxidation resistance. The silicon alkyne-modified SiBCN precursor is adopted as impregnation matrix; a carbon fiber is taken as a reinforcement body; and the novel SiBCN ceramic matrix composite material is prepared by an infiltration pyrolysis method. The composite material has good mechanical property and excellent oxidation resistance.
