摘要：

The carbon felt/carbon (C/C) composites with 2wt% hafnium carbide were damaged by using a split Hopkinson pressure bar (SHPB) with the maximum impact loading of 137MPa or so, and the effect of dynamic impact damage on ablative properties of the C/C composites was investigated in oxyacetylene flame equipment with high velocity gas. The effect of impact damage on ablative mechanism of the composites was also discussed based on SEM observation. The results show that the linear ablation rate is increased by 118%, and the mass ablation rate is increased by 40% for the damaged C/C composites than those measured for the undamaged C/C composites.
