摘要
应用物理学的逾渗理论对PIP法制备Cf/SiC复合材料浸渍和裂解过程进行了模拟解释和分析 ,并在此基础上对工艺进行了优化 ,使Cf/SiC复合材料的密度由原来的 1.75g/cm3提高到 2 .0 3g/cm3,强度由原来的 30 0MPa提高到 5 0 0MPa。
Percolation theory of physics is applied to simulate, explain and analyze infiltration and pyrolysis process of C f/SiC composites by PIP. According to the models,the fabricating process of C f/SiC composites is optimized, density of the C f/SiC is condensed to 2.03 g/cm 3 from 1.75 g/cm 3,the strength reached 500 MPa from 300 MPa as a result,and mechanical properties could be obtained repeatedly.
