Abstract:The shortcoming of easy oxidation for carbon/carbon(C/C) composites in oxidizing environments has limited the applications of C/C composites in aerospace field. Adding ultra-high temperature ceramics (UHTCs) to C/C composites can improve their ablation resistance. The technologies for matrix modification, including chemical vapor infiltration, precursor infiltration pyrolysis, reactive melt infiltration, and the advantages and disadvantages of these technologies were introduced and analyzed. Recent progress on anti-ablation properties for C/C composites at ultra-high temperature was reviewed. Some results about the anti-ablation property of C/C composites were also summarized. Finally, the potential development direction of improving long-time ablation resistance for C/C composites was proposed.
Key words: C/C composites; ultra-high temperature ceramic; matrix modification; anti-ablation property
