Abstract

C/C-ZrC composites with continuous ZrC matrix were prepared by precursor infiltration and pyrolysis process using zirconium-containing polymer. Ablation properties of the composites were investigated by oxyacetylene flame with heat flux of 2380 and 4180kW/m², respectively. The results showed that C/C-ZrC composites exhibited excellent ablation resistance under the heat flux of 2380kW/m² for 120s and a tree-coral-like ZrO₂ protective layer formed after ablation. However, when the heat flux increased to 4180kW/m², the maximum temperature of ablated surface reached 2500°C and a strong degradation of ablation resistance was observed due to the weak bonding between the formed ZrO₂ layer and the composites. The flexural strength of C/C-ZrC composites was 110.7±7.5MPa. There were a large number of carbon fiber bundles pull-out, and the composites exhibited a pseudo-plastic fracture behavior.
