One-way high-temperature-resistant and ablation-resistant ceramic-based composite material and preparation method thereof
The invention discloses a one-way high-temperature-resistant ablation-resistant ceramic-based composite material and a preparation method thereof, and belongs to the technical field of composite materials and preparation.The preparation method comprises the steps that mesophase pitch-based carbon fibers are put into an organic carbon solution to be soaked, and the soaked mesophase pitch-based carbon fibers are put into a mold to prepare a one-way high-thermal-conductivity carbon fiber preform; and carrying out multiple rounds of dipping-curing-cracking process treatment on the unidirectional high-thermal-conductivity carbon fiber preform by using the ultra-high-temperature ceramic precursor solution twice in sequence to obtain the unidirectional high-temperature-resistant anti-ablation ceramic-based composite material. The mechanical property, the heat conduction property, the high-temperature resistance and the ablation resistance of the material in a specific direction can be improved at the same time.
本发明公开一种单向耐高温抗烧蚀陶瓷基复合材料及其制备方法，属于复合材料及制备技术领域，通过将中间相沥青基碳纤维放入有机碳溶液中进行浸渍，放置在模具中制备单向高导热碳纤维预制体；前后两次使用超高温陶瓷前驱体溶液对单向高导热碳纤维预制体进行多轮次的浸渍‑固化‑裂解工序处理，得到单向耐高温抗烧蚀陶瓷基复合材料。本发明能够同时提高材料在一个特定方向上的力学、导热及耐高温抗烧蚀性能。
