| Abstract: | The parameters of CVI process have prominently influenced on the densification rate, density distribution and the properties of C/C composite. Guaranteed the densification rate, C/C composite with uniform density distribution can be obtained by controlling the processing parameters. The influences of AS/VR ratio, carbon source, partial pressure of the carbon source, infiltration temperature and residence time on uniform densification of C/C composite are discussed, respectively. And the synergies of these parameters also have been summarized. |
