摘要：
C/C-HfC composites were prepared by precursor infiltration and pyrolysis using HfC precursor. The microstructure, mechanical properties, and ablation behavior were investigated. The C/C-HfC composites showed good ablation resistance with a surface temperature over 2573 K during ablation. The ablation process was divided into two steps, with the ablation rate dominated by various mechanisms. During ablation, tree-coral-like HfO2 particles formed and functioned as thermal barrier, and the HfCxOy phase acted as oxygen diffusion barrier, protecting the composites from further ablation.
