High-entropy ceramic-based composite material and preparation method thereof
The invention relates to a high-entropy ceramic-based composite material and a preparation method thereof. The preparation method comprises the following steps: dipping a carbon fiber preform in a high-entropy carbide ceramic precursor solution containing Ti, Zr, Nb, Mo, Hf and Ta metal elements, controlling the heating rate, and sequentially carrying out high-temperature curing and cracking to obtain a high-entropy ceramic (Ti < x > 1 Zr < x > 2 Nb < x > 3 Mo < x > 4 Hf < x > 5 Ta < x > 6) C matrix with a continuous network structure; the steps of dipping, curing and high-temperature cracking are repeated until the density of the matrix reaches the specified density, and the high-entropy ceramic (Ti < x > 1 Zr < x > 2 Nb < x > 3 Mo < x > 4 Hf < x > 5 Ta < x > 6) C-based composite material is obtained. The invention also relates to the high-entropy composite material prepared by the method. The high-entropy ceramic-based composite material prepared by the method disclosed by the invention has good mechanical properties.
