烧蚀材料在高温环境中因物理、化学和力学因素造成质量损失 ,影响其性能。建立相应的热化学和热力学烧蚀模型 ,分析其传热特性和力学性能的演化规律 ,建立材料的热毁损判据 ,是复合材料防热结构设计所面临的重要问题。本文综述了近年来文献中对炭基复合材料烧蚀机理的研究 ,并对几种烧蚀模型进行了评价 Ablation materials in the high temperature environment due to physical, chemical and mechanical factors resulting in quality loss, affecting its performance. Establishing the corresponding thermochemical and thermodynamic ablation model, analyzing the evolution of heat transfer and mechanical properties, and establishing the thermal damage criterion of the material are important issues in the design of heat-resisting composite structures. In this paper, the recent literature review of the ablation mechanism of carbon-based composites, and several ablation models were evaluated
