摘要：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. (c) 2012 Elsevier Ltd. All rights reserved.
