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.
