Effect of ablative angles on the ablation behaviors of ZrB2-SiC modified carbon/carbon composites

To analyze the effect of different ablation angles on the ablative property of carbon/carbon(C/C) composites modified by ZrB2-SiC, C/C-ZrB2-SiC composites (ZS) were prepared via precursor infiltration and pyrolysis (PIP). The prepared composites (ZS) were then ablated by oxyacetylene flame at 90° and 0° angles (ZS-90° and ZS-0°), respectively. The results show that, at ZS-0° angle, the ablation resistance was worse due to the existence of...
