| Abstract: | C/C-SiC composite was fabricated by reactive molten infiltrating(RMI) Si to C/C preforms with pyrolitic carbon,resin carbon,pyrolitic carbon and resin carbon which were prepared by chemical vapor infiltration(CVI),resin impregnation and carbonization(I/C),CVI and I/C(CVI& I/C) respectively.The microstructure,mechanical properties and oxidation resistance of the composites were studied.The results show that RMI C/C-SiC composite consists of SiC,C and residual Si.The resin carbon in I/C preform is easier to r... |
