Heat-conducting anti-scouring ceramic-based composite material and preparation method thereof
The invention relates to a heat-conducting anti-scouring ceramic-based composite material and a preparation method thereof. The method comprises the following steps: weaving high-thermal-conductivity carbon fibers into high-thermal-conductivity carbon cloth; uniformly coating phenolic resin on the high-thermal-conductivity carbon cloth to obtain a high-thermal-conductivity prepreg; sequentially carrying out mold pressing, curing and cracking on the high-thermal-conductivity prepreg to obtain a high-thermal-conductivity carbon/carbon green body; reacting and infiltrating the high-heat-conductivity carbon/carbon green body and hafnium-zirconium-silicon alloy to obtain a heat-conducting ceramic matrix; the anti-scouring coating is prepared on the surface of the heat-conducting ceramic matrix through a chemical vapor deposition method, and the heat-conducting anti-scouring ceramic-based composite material is prepared. The prepared heat-conducting anti-scouring ceramic-based composite material is high in heat conductivity, excellent in high-temperature anti-ablation performance and excellent in high-temperature anti-scouring performance, and has a wide application prospect in aerospace crafts.
