Preparation method for ultra-high-temperature ceramic modified C/C composite material
The invention relates to a preparation method for an ultra-high-temperature ceramic modified C/C composite material. The preparation method comprises: carrying out a reaction on an ultra-high-temperature ceramic precursor solution at a high temperature by adopting a chemical liquid phase vaporized deposition process technology to generate a ceramic and pyrolytic carbon; depositing the ceramic and pyrolytic carbon; in a carbon fiber preform; and finally carrying out thermal treatment to obtain the ultra-high-temperature ceramic modified C/C composite material. The innovation of the preparation method provided by the invention is that the ultra-high-temperature ceramic modified C/C composite material is prepared by adopting the chemical liquid phase vaporized deposition process, so that the problems that a conventional process method is long in production period, has a certain damage to fiber and the like are overcome, and the ultra-high-temperature ceramic modified C/C composite material which is uniformly distributed is prepared within a short time. In the method, the component proportion, the chemical liquid phase vaporized deposition process parameters and the thermal treatment process have a great influence on the experimental result. By adjusting the experimental parameters, the ultra-high-temperature ceramic which is uniformly distributed can be obtained in the C/C composite material, so that the anti-oxidizing and ablation-resisting performances of the C/C composite material are favorably enhanced.
