摘要	In order to reveal the detailed thermal response of thermal protective composites under high temperature, the carbonized ablation process of composite materials is achieved through the method of finite element numerical simulation. Established a thermal composite finite element model for numerical analysis of ablation process of carbide primarily include internal pyrolysis, material quality loss, heat transfer modeling, carbon coating on the surface of erosion models, and the ablation process of carbon-phenolic composites is numerical simulated. Results show that ablation of the material is the result of combination of a variety of factors, with the ablation time increases, material internal pyrolysis reaction occurs, and the occurrence of layered phenomenon causing the materials been divided into carbide layer, pyrolytic layer and original material layer and the material layer moving over time to the inside material. The wall temperature decreases with the increase of the ablation volume of the material, and the carbonation ablation of materials has played an effective thermal protective effect. The results of numerical simulation meet the requirements of the research program. The research method is applicable for any carbide ablative thermal protection materials.
