Carbon fiber-enhanced ZrB2-ZrN composite ceramic-based composite material and preparation method thereof
The invention discloses a carbon fiber-enhanced ZrB2-ZrN composite-ceramic-based composite material and a preparation method thereof. In the composite material, carbon fibers are employed as an enhancement body and ZrB2-ZrN composite ceramic is employed as a base body. The preparation method includes the following steps: with propylene as a precursor, depositing a carbon coating layer on surface of the carbon fiber enhancement body through a chemical vapor deposition process to obtain the carbon fiber enhancement body of which the surface is deposited by the carbon coating layer; compacting the carbon fiber enhancement body of which the surface is deposited by the carbon coating layer to obtain a porous C/BN prefabricate; and performing fusion infiltration to the porous C/BN prefabricate with zirconium metal or zirconium alloy to obtain the carbon fiber-enhanced ZrB2-ZrN composite-ceramic-based composite material. The preparation method is simple, is low in cost and is short in period. The composite material is high in compactness degree, is high in ceramic phase volume percentage and is homogeneous in distribution.
