炭纤维编织物中引入SiC微粉的超声工艺研究
, PP. 31-34
Keywords: 超声浸渍法,炭纤维三维编织物,SiC微粉,陶瓷基复合材料,先驱体浸渍裂解
Abstract:
为缩短先驱体浸渍裂解制备炭纤维三维编织物(3D-BCf)增强SiC陶瓷基复合材料的工艺周期,在3D-BCf中采用超声浸渍法预先引入SiC微粉.考察了微粉粒度、浆料SiC/无水乙醇(EtOH)质量比等参数对引入SiC微粉体积分数的影响.结果表明,当SiC微粉粒度为0.4μm、浆料SiC/EtOH质量比为11时超声浸渍效果最佳,在3D-BCf中引入SiC微粉的体积分数可达到16.4%,预先引入SiC微粉可以缩短材料的致密化周期.
