Two-dimensionally (2D) reinforced C/C-SiC-ZrC composites were prepared by ICVI combined with RMI method. The ablation properties of the composites were tested under an oxyacetylene flame. The results indicate that the temperature of RMI has remarkable effect on the microstructure and ablation properties of C/C-SiC-ZrC composites, the linear and mass ablation rates of the C/C-SiC-ZrC prepared at 2300 degrees C are greatly reduced compared with those of C/C-SIC-ZrC prepared at 2000 degrees C and C/C composites. The formation of a dense ZrC-SiC coating and its oxide layer are the reasons for high ablation resistance. (C) 2012 Elsevier Ltd. All rights reserved.
