| titleOfInvention | Preparation method of Hf-Ta-C reinforced C/SiC ceramic matrix composite |
| abstract | The invention relates to a preparation method of an Hf-Ta-C reinforced C/SiC ceramic matrix composite, which comprises the following steps: (1) providing a carbon/carbon substrate; (2) preparing the carbon/carbon matrix into the C/SiC ceramic matrix composite by using a silicon alloy as a reactant and adopting a reaction infiltration method; (3) and reacting the hafnium-tantalum precursor solution serving as a reactant with the C/SiC ceramic matrix composite material by adopting a dipping pyrolysis method to prepare the Hf-Ta-C enhanced C/SiC ceramic matrix composite material. The preparation method gives full play to the high efficiency advantage of the reaction infiltration method, and further reduces the porosity and the ablation resistance of the composite material by means of the impregnation pyrolysis method, thereby effectively solving the problem of poor ablation resistance caused by more pores in the C/SiC ceramic matrix composite material. |
