| Abstract: | Matrix modification of C/C composites is one of the principal methods taken for anti-oxidation protection. In this paper, on the basis of the latest developments in C/C composites, the three kinds of methods of matrix modification are emphasized in the discussion. It is concluded that matrix replacement will be a focus for research, and SiC ceramics is better to replace carbon matrix. The main advantages and shortages of chemical vapor infiltration method, precursor infiltration pyrolysis method, and liquid silicon infiltration method for fabricating C/C-SiC composites are summarized. Lastly, the direction of oxidation-resistance for C/C composites is pointed out. |
