Superior ablation resistance of C/C–HfCSiC composite sharp leading edges above 2500 °C prepared by precursor infiltration and pyrolysis

HfCSiC-modified carbon/carbon composite (C/C–HfCSiC) sharp leading edges (SLEs) were prepared via precursor infiltration and pyrolysis for potential hypersonic applications. The effect of SiC proportion on the ablation behavior of the SLEs under oxyacetylene flames with 2.38 MW/m2 and 4.18 MW/m2 w...
