摘　　要：采用常压浸渍炭化(PIC)和高压浸渍炭化(HPIC)工艺制备了不同密度的轴棒法编织C/C复合材料,观察了材料的金相结构,通过炭棒顶出实验分析了材料的界面结合情况。结果表明:轴棒法C/C复合材料界面间隙并未随材料密度的增大而逐渐减小;材料密度增大,界面结合强度升高,达到最大值后呈现下降趋势,最后趋于稳定。Axial carbon rod woven carbon/carbon composites with di{{erent density were prepared by the process of normal-pressure impregnation/carbonization and high-pressure impregnation/carbonization. The metallurgi cal structures were observed and the interracial bonding properties were investigated using the carbon rod push-out techniques. The results show that, with increasing density of composite, the interracial gap length had no diminution. The interracial bonding strength increased with increasing density, presented descending trend after maximizing, and tended to stabilization in the end.
