Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of ultra-high-temperature thermal protection structures, and in particular relates to a ceramic-based composite material with a boride-nitride composite ultra-high-temperature ceramic as a matrix and a preparation method thereof. Background technique [0002] Hypersonic vehicles have become the main development direction of new hypersonic weapon systems and aerospace, and will play an important role in future national security and development. With the increase of the flight speed of hypersonic vehicles, the demand for ultra-high temperature resistant and ablation-resistant materials is becoming more and more urgent. The existing materials can no longer meet the needs of the development of thermal protection systems and propulsion systems of hypersonic vehicles. It is necessary to develop a new generation of resistant materials. Ultra-high temperature, anti-ablation, anti-thermal shock, high reliability new ...
