C/SiC foam skeleton reinforced SiC/Al2O3 ceramic-based composite material and preparation method thereof
The invention relates to the technical field of ceramic-based composite materials, in particular to a C/SiC foam skeleton reinforced SiC/Al2O3 ceramic-based composite material and a preparation method thereof. Light and high-strength C foam is adopted as a framework material of the aerogel composite material, a C foam framework is mechanically modified and enhanced through a SiC coating, the SiC/Al2O3 ceramic matrix composite material is obtained through a precursor dipping pyrolysis process, mutual embedding and interlocking of SiC and Al2O3 ceramic matrixes are achieved through the alternate structural design of the SiC and Al2O3 ceramic matrixes, and the SiC/Al2O3 ceramic matrix composite material is prepared. And the addition of the Al2O3 ceramic matrix greatly promotes the high temperature resistance and oxidation resistance of the C/SiC foam skeleton enhanced SiC/Al2O3 ceramic-based composite material, and is beneficial to further application of the composite material in a high-temperature aerobic environment.
本发明涉及陶瓷基复合材料技术领域，更具体而言，涉及C/SiC泡沫骨架增强SiC/Al2O3陶瓷基复合材料及其制备方法。本发明采用了轻质高强的C泡沫作为气凝胶复合材料的骨架材料，并通过SiC涂层对C泡沫骨架实现了力学改性增强，SiC/Al2O3陶瓷基复合材料通过前驱体浸渍热解工艺得到，通过SiC和Al2O3陶瓷基体的交替结构设计，实现了SiC和Al2O3陶瓷基体的互嵌互锁，且Al2O3陶瓷基体的添加极大促进了C/SiC泡沫骨架增强SiC/Al2O3陶瓷基复合材料的耐高温性能和抗氧化性能，有利于其在高温有氧环境的进一步应用。
