Preparation method of silicon carbide fiber reinforced silicon carbide composite material
The invention discloses a preparation method of a silicon carbide fiber reinforced silicon carbide composite material. The method specifically comprises the following steps: S1, selecting raw materials, S2, weaving a fiber skeleton, S3, preparing a mixed impregnation liquid, S4, carrying out pressure sintering treatment, S5, carrying out material modification treatment, and S6, carrying out cracking treatment. The invention relates to the technical field of material preparation. The preparation method of the silicon carbide fiber reinforced silicon carbide composite material Can realize that when a silicon carbide skeleton blank structure is subjected to hot-pressing sintering, the sintering temperature is reduced; liquid silicon is used for filling air holes, so carbon and silicon are well combined, a process of filling air holes is well achieved, the purpose of enhancing the densification degree of the silicon carbide composite material is achieved, the mechanical property of the silicon carbide composite material is guaranteed, the heat-conducting property of the material can be enhanced, the porosity can be well reduced, the densification degree and the heat conductivity of thematerial are improved, and the service life of the silicon carbide composite material is greatly prolonged.
