Preparation method of carbon fiber toughened silicon carbide-zirconium carbide composite material
The invention relates to a preparation method of a carbon fiber toughened silicon carbide-zirconium carbide composite material. The preparation method comprises the following steps: (1) providing a carbon fiber preform; (2) forming a porous carbon/carbon composite material with pores in the carbon fiber preform; (3) using the porous carbon/carbon composite material to prepare a carbon/silicon carbide-zirconium carbide ceramic-based composite material by adopting a reaction infiltration method; and (4) preparing the carbon fiber toughened silicon carbide-zirconium carbide ceramic-based composite material by adopting an impregnation cracking method. According to the preparation method, a reaction infiltration method and an impregnation cracking method are combined, so that high efficiency and low cost can be guaranteed, low porosity can be considered, the preparation period is effectively shortened, and the mechanical property of the ceramic-based composite material is improved; and theproblem that the performance is poor due to the fact that the porosity is high when a carbon/silicon carbide-zirconium carbide composite material is prepared through a reactive infiltration method inthe past is solved.
本发明涉及一种碳纤维增韧碳化硅‑碳化锆复合材料的制备方法。所述制备方法包括：(1)提供碳纤维预制体；(2)在碳纤维预制体内部形成有孔隙的多孔碳/碳复合材料；(3)采用反应熔渗法将所述多孔碳/碳复合材料制成碳/碳化硅‑碳化锆陶瓷基复合材料；(4)采用浸渍裂解法制备所述碳纤维增韧碳化硅‑碳化锆陶瓷基复合材料。该制备方法通过将反应熔渗法与浸渍裂解法相结合，既可以保证高效低成本，又可以兼顾低孔隙率，从而有效降低制备周期和提升陶瓷基复合材料的力学性能，解决了以往通过反应熔渗法制备碳/碳化硅‑碳化锆复合材料中由于孔隙率较高导致性能较差的问题。
