Abstract
C/C composites were prepared by chemical vapor infiltration (CVI), and then were subjected to Si, Zr, and MoSi2 reactive melt infiltration (RMI) to obtain C/C-SiC, C/C-SiC-ZrC, and C/C-SiC-ZrC-MoSi2 composites. The ablation behavior of these three composites was evaluated by high-energy CO2 laser irradiation. The surface temperature distribution of composite materials was simulated by finite element analysis. The results show that the ablation resistance mechanisms of the three materials are entirely different. The C/C-SiC-ZrC-MoSi2 composite showed the best ablation performance among them. It is attributed to the lower oxygen permeability and richer heat dissipation mechanism of the C/C-SiC-ZrC-MoSi2 composite within the total temperature threshold.
