中文摘要：

为了在厚度为10mm的3D碳纤维预制体中大量引入SiC微粉，在料浆不变的基础上采用真空浸渗法、加压浸渗法、加压过滤法、真空吸滤法等四种料浆浸渗法进行试验，并对引入微粉的量及其分布进行分析对比。结果表明，对于含1μm SiC微粉4vol％的料浆，加压过滤法效果最佳，3次浸渗即能引入27．4vol％的SiC微粉，SiC微粉均匀致密填充。

英文摘要：

In order to introduce a mass of SiC fillers into 10mm thick 3-D carbon fiber perform, four slurry infiltration method were applied ： vacuum infiltration, pressure infiltration, pressure filtration,and vacuum suction straining. The volume fraction of introduced SiC fillers in carbon fiber perform and its distribution were investigated. The results showed that pressure filtration led to the best results. Using a slurry containing 4vol% 1μm SiC fillers, thrice infiltration introduced 27.4vol% SiC fillers, which packed densely and uniformly.
