Enhanced Ablation Resistance of Phenolic Resin at 1400–2300 °C through Zirconium-Doping-Induced Heterogeneous Melt Strengthening and Graphitization Transition

Abstract Boron oxide derived from boron-phenolic resin suffers severe viscosity reduction and volatilization at high temperatures, failing to form a robust ceramic melt layer and severely limiting its application in hypersonic vehicles. We designed a zirconium-doped polyborosilan...
