Progress in preparation and ablation resistance of ultra-high-temperature ceramics modified C/C composites for extreme environment

Abstract Carbon/carbon (C/C) composites have received considerable attention for one of the most promising materials in thermal-structural applications owing to their low density, excellent mechanical strength at high temperature, and superior thermal shock resistance. However, C/C are susceptible destructive oxidation atmospheric environment temperature. Matrix modification by adding ultra-high-temperature ceramics (UHTCs) into carbon substrate has been proved be a favorable route achieve improved ablation resistance composites. In this work, main fabrication approaches UHTCs-modified were summarized, including chemical vapor infiltration/deposition, precursor infiltration pyrolysis, reactive melt infiltration, slurry advantages drawbacks each process also briefly analyzed. addition, anti-ablation properties under different tests with shape specimens introduced. Finally, some likely future challenges research directions development application these presented.
