Preparation method of silicon carbide nanowire enhanced C/C-SiC-ZrB2 ceramic-based composite material
The invention relates to a preparation method of a silicon carbide nanowire enhanced C / C-SiC-ZrB2 ceramic-based composite material. A pretreated carbon fiber prefabricating body is thermally treated to obtain a silicon carbide nanowire. The silicon carbide nanowire prepared by a sol-gel carbon-thermal reaction method is evenly distributed at the inner part of a porous carbon / carbon composite material. Subsequently, pyrolytic carbon deposited in an isothermal chemical vapor deposition furnace is coated at the surface of the silicon carbide nanowire, thus the dropping, growing and rupture of the silicon carbide nanowire in the following reaction and infiltration processes are effectively avoided. A ceramic-based composite material carbon fiber, a silicon carbide nanowire and a pyrolytic carbon middle layer after reaction and infiltration are not eroded by a high-temperature metal bath and are well preserved; thus the physical performance of the composite material can be improved. Compared with the C / C-SiC-ZrB2 ceramic-based composite material without adding the silicon carbide nanowire, the bending strength and the fracture toughness property of the silicon carbide nanowire enhanced C / C-SiC-ZrB2 ceramic-based composite material are improved by 26.9-41.3% and 45.2-59.1% respectively.
