Several intermediate steps were applied before the precursor infiltration and pyrolysis process to improve the infiltration of SiC slurry for promoting the infiltration of SiC slurry into fiber voids. These steps include sonication, popping, electrophoretic deposition, vacuum infiltration and cold isostatic pressing (CIP). The intermediate processes, especially popping and CIP, had a beneficial effect on green density enhancement and improving the homogeneous infiltration of the slurry into fiber fabrics. The density of the SiC_fiber/SiC_filler green body was 2.20 g/cm³, which corresponded to 68 % of relative density. The SiC_f/SiC composite has a high density of 2.65 g/cm³ after seven PIP cycles.

在前体渗透和热解过程之前应用了几个中间步骤，以改善SiC浆料的渗透性，以促进SiC浆料向纤维空隙中的渗透。这些步骤包括超声处理，爆裂，电泳沉积，真空渗透和冷等静压（CIP）。中间过程，特别是膨化和CIP，对提高生坯密度和改善浆料向纤维织物的均匀渗透具有有益的作用。SiC_纤维/ SiC_填料生坯的密度为2.20g / cm ³，相当于相对密度的68％。在七个PIP循环后，SiC _f / SiC复合材料具有2.65 g / cm ³的高密度。
