Abstract By applying the combinational process of polymer impregnation & pyrolysis and chemical vapor infiltration (PIP+CVI), the present work successfully carried out the fabrication of a 2.5 dimensional and a 3 dimensional SiC/SiC composite, as well as the porosity, thermal conductivity, mechanical property and microstructure characterization and analyses for the products. The low density (1.98-2.43 g·cm^-3) and low thermal conductivity (0.85-2.08 W·m^-1·K^-1) of the PIP+CVI 2.5D and 3D SiC/SiC composites could be confirmed from the experiment. And moreover, it can be deduced that the pre-weave CVI fiber coating improves the fiber-matrix interface shear strength and hence the resultant composite’s mechanical properties, while the effectiveness of post-pyrolysis overall CVI coating toward the density, thermal conductivity and mechanical properties promotion is notable for the 2.5D SiC/SiC composite but inconspicuous for the 3D one.

Key words： polymer impregnation and pyrolysis (PIP) chemical vapor infiltration (CVI) braiding structure SiC-fiber-reinforced SiC matrix (SiC/SiC) composite density thermal conductivity mechanical property
