Abstract

Carbon/carbon composites modified by ZrB₂-ZrC-SiC particles (C/C-Z-SiC), C/C-Z and C/C were ablated by oxyacetylene torch using two different heat fluxes to investigate the effect of doped ceramic particles. Results indicated that C/C-Z-SiC had the best ablation property in heat flux of 2.38MW/m² whereas their ablation rates increased fastest when heat flux rising from 2.38 to 4.18MW/m². C/C composites had the poorest ablation property in the lower heat flux and their ablation rates increased slowest. Thermal mismatch of Z, SiC and C and evaporation of SiO₂ induced the various ablation behavior.
