利用碳纤维编织布为增强体,采用混合粉料模压成型工艺制备 C/C-SiC 复合材料,分析了各个因素对 C/C-SiC 复合材料密度及强度影响的大小以及显著性。研究表明,树脂与石墨粉比例和纤维含量对 C/C-SiC 复合材料密度的影响比较大,而硅粉含量以及配比浓度的影响较小且基本相同;同时树脂与石墨粉比例这一因素对 C/C-SiC 复合材料强度影响也非常显著。并且随着树脂含量的减少,C/C-SiC 复合材料强度降低。
Carbon fiber woven cloth was used as strengthen body in this paper,prepared C/C-SiC composites by mixed powder molding process,various factors that can influence the density and intensity of C/C-SiC compos-ite was analyzed.Research shows influence of resin with graphite powder proportion and fiber content on the C/C-SiC composite density is significant.But impact of content of silicon powder and concentration was negligible. At the same time,the factor of resin with graphite powder proportion on strength of C/C-SiC composite is also very significant.As the resin content decreased,the strength of C/C-SiC composites decreased.
