Improved ablation resistance of C <sub>sf</sub> /SiBCN composites densified by PIP process: Ablation behavior and damage mechanism

Abstract To enhance the ablation resistance of porous C sf /MA–SiBCN composites, the polymer infiltration and pyrolysis (PIP) process is adopted to obtain layered C sf /SiBCN composites containing MA–SiBCN and PDCs–SiBCN. After ablation for 10 s, the ablative layer fails to remain on the C sf /MA–SiBCN surface with mass ablation rate of 0.062 g/s and linear ablation rate of 0.208 mm/s, while the dense C sf /SiBCN surface is covered by a dense and stable ablative layer mainly consisting of amorphous SiO 2 glassy phase due to the synergistic ablation effect of MA–SiBCN and PDCs–SiBCN, which could resist the intense scour by ablation flame and prevent internal corrosion, and thus the ablation resistance improves with a 37% decrease in mass ablation rate (0.039 g/s) and an 18% decrease in linear ablation rate (0.171 mm/s), respectively.
