A kind of ultra-high temperature anti-ablation thermally conductive composite material and preparation method thereof |
| abstract |
The invention relates to an extremely high-temperature anti-ablation heat-dredging composite material and a preparation method thereof. The method: using high thermal conductivity carbon fiber and polyacrylonitrile-based carbon fiber mixed to weave into a high thermal conductivity carbon fiber preform, or using a high thermal conductivity carbon fiber rod to weave into a high thermal conductivity carbon fiber preform; chemical vapor deposition method and high temperature graphitization treatment method are used in sequence in the process. A carbon interface layer is prepared on the fiber surface of the high thermal conductivity carbon fiber preform to obtain a thermally conductive composite material preform; the polycarbosilane ceramic precursor and the hafnium tantalum ceramic precursor are used as the impregnating liquid in turn to make the thermally conductive composite material preform through the PIP process. A thermally conductive ultra-high temperature ceramic matrix composite material; an anti-ablation ceramic coating is prepared on the surface of the thermally conductive ultra-high temperature ceramic matrix composite material to obtain an ultra-high temperature ablation-resistant and thermally conductive composite material. The extremely high-temperature ablation-resistant thermally conductive composite material prepared by the invention has the characteristics of high thermal conductivity, high density, excellent mechanical properties, and excellent high-temperature ablation resistance. |
