Ceramic-based composite material as well as preparation method and application thereof
The invention discloses a ceramic-based composite material as well as a preparation method and application thereof. The ceramic-based composite material comprises the following components in percentage by mass: 20%-30% of carbon fibers, 20%-40% of C-VDC, 10%-25% of CVD-SiC, 5%-25% of PIP-SiC, 5%-15% of GSI-SiC, 5%-15% of TiC and less than 3% of residual Si. The preparation method sequentially comprises the following steps: deposition of a C layer on a carbon fiber preform; deposition of a SiC layer; impregnation and cracking of a precursor for preparation of SiC; impregnation of asphalt and carbonization; preparation of TiC; and gas-phase siliconizing. The ceramic-based composite material disclosed by the invention has the advantages of excellent friction and wear resistance, mechanical properties and thermal properties, the content of each component can be flexibly designed and adjusted according to actual requirements, and the requirements of the field of high-performance braking andaerospace structural parts on material properties are met.
本发明公开了一种陶瓷基复合材料及其制备方法和应用,陶瓷基复合材料包括以下质量分数的组分:碳纤维为20%~30%,CVD‑C为20%~40%,CVD‑SiC为10%~25%,PIP‑SiC为5%~25%,GSI‑SiC为5%~15%,TiC为5%~15%和残余Si小于3%。制备方法依次包括在碳纤维预制体上沉积C层、沉积SiC层、先驱体浸渍裂解制备SiC、浸渍沥青‑碳化、制备TiC和气相渗硅。本发明的陶瓷基复合材料具有摩擦磨损性能、力学性能和热学性能优异的优点,各组分含量可根据实际需求进行灵活设计与调整,满足了高性能制动和航空航天结构件领域对材料性能的要求。
