An advanced method combines using ZrB2 ceramic nanoparticles as filler within the carbon fiber–resol type-phenolic resin (C/Ph) composite for the superior ablation properties of thermal protection systems. The oxy-acetylene torch test suggested that ZrB2 nanoparticles could effectively protect C/Ph composite from ablation at 2,000 °C for 160 s. The ablation rate decreased when C/Ph composite was filled...
