摘要：

Two-dimensional C/ZrC-SiC composites were fabricated by chemical vapor infiltration (CVI) process combined with a modified polymer infiltration and pyrolysis (PIP) method. Two kinds of ZrC slurries (ZrC aqueous slurry and ZrC/polycarbosilane slurry) were employed to densify composites before the PIP process. The as-produced C/ZrC-SiC composites exhibited better mechanical properties than the C/SiC composites densified only by CVI and PIP process. Structural evolution for C/ZrC-SiC composites treated in the range 1200-1800 degrees C mainly consisted of the change of SiC whiskers and the decomposition of polymer derived ceramic.
