Carbon fiber reinforced ceramic matrix composite material and preparation method thereof
The invention discloses a preparation method of a carbon fiber reinforced ceramic-based composite material, which comprises the following steps: impregnating a carbon fiber preform with a boron carbide colloid to obtain the carbon fiber preform attached with the boron carbide colloid; aging the boron carbide colloid attached to the carbon fiber preform to obtain an initial carbon fiber blank; dipping the initial carbon fiber blank by using a precursor solution comprising a silicon carbide precursor and an ultrahigh-temperature ceramic precursor to obtain an initial carbon fiber blank attached with the precursor solution; curing the precursor solution attached to the initial carbon fiber blank to obtain a carbon fiber blank; and allowing the carbon fiber blank to be subjected to heat treatment to obtain the carbon fiber reinforced ceramic matrix composite. The composite material prepared by the invention has the advantages of ultrahigh temperature resistance, strong ablation resistance, high overall strength, good fracture toughness resistance, strong oxidation resistance in a wide temperature range and the like.
