Abstract

Carbon-phenolic (C-Ph) composites are well fabricated to meet the requirements of thermal protection system by introducing ZrB₂ particles. TG analysis demonstrates that the existence of ZrB₂ particles could obviously aggrandize the char yield of phenolic, although it does not enhance the thermal stability of phenolic. What is more, the employed method of introducing ZrB₂ could notably improve ablation resistance and insulation performance of C-Ph composites, which is mainly owing to the formation of ZrO₂ and B₂O₃. As depicted in the microstructure, the ablation rate of matrix is evidently higher than carbon fibers in the C-Ph composites. However, the ablation rate of carbon fibers is identical to matrix in Z C-Ph composites.
