Research Progress on Ultrahigh-Temperature Ceramics Modified C/C Composites

C/C composites have excellent high-temperature mechanical properties and are one of the most promising high-temperature structural materials. However, poor oxidation and ablation resistance of the C/C composites in high-temperature oxygen-containing environments seriously hinder their practical applications. Ultrahigh-temperature ceramics (UHTCs)-modified C/C composites (C/C-UHTCs) are considered to be the most effective way to improve the oxidation and ablation resistance of C/C composites, demonstrating significant application prospects in aerospace and related fields. This article reviews recent research progress on C/C-UHTCs composites, including application prospects, performance testing methods, preparation techniques, phase composition, structural design principles, microstructural characteristics, as well as oxidation/ablation mechanisms. Addressing current challenges in C/C-UHTCs composites and future research directions are also proposed.
