摘　　要：以聚碳硅烷和硼化锆前驱体为原料,采用前驱体浸渍裂解工艺制备Cf/SiC-ZrB2复合材料,首先研究了粘度对前驱体溶液交联固化和材料致密度的影响,进而研究了浸渍压力等条件对材料性能的影响。结果表明:合理的溶液组分配比关系到混合溶液的粘度,是影响浸渍性能的主要因素;真空加压浸渍的方法可以减少制备周期,快速提高材料致密度,对材料的各方面性能都有明显的改善。Using PCS and ZrB2 precursor as raw materials ,we prepared Cf/SiC-ZrB2 composites through precursor infiltration and pyrolysis process（PIP） .Firstly ,we studied the influence of viscos‐ity on the efficiency of precursor infiltration and density of the composites .Then the effect of infiltra‐tion pressure on the performance of composite materials w as studied .T he results are that the viscosi‐ty of the mixed solution depended on the component proportion of the solution ,w hich are the main in‐fluencing factors of the performance of infiltration .Through vacuum -pressure infiltration method , the fabrication period can be reduced ,so the composites can be densified faster and the performance of the materials can be improved greatly .
