| 目的 研究低密度碳/酚醛复合材料在不同地面加热实验测试响应的差异性，指导材料在实际应用环境下的高温响应分析。方法 对低密度碳/酚醛复合材料开展了热流为400 kW/m2的单侧石英灯辐射加热实验，利用热电偶测温系统测量试件在加热过程中不同位置的温度时间历程，并对试件的烧蚀形貌和微观结构进行观测。同时与热流为464 kW/m2的氧乙炔加热陶瓷板辐射加热实验结果进行对比分析，并且采用有限元方法对材料的传热传质多场耦合计算进行分析。结果 对于石英灯辐射加热，在测量点升温到接近200 ℃时，温度响应拐点都依次出现。由于加热的辐射热源不同，在不同的辐射波段下，多孔材料吸收和发射的热量不同，短时间内氧乙炔加热陶瓷板辐射加热使材料内部升温速率比石英灯辐射加热实验的要快，但长时间加热时现象刚好相反。结论 进行传热传质多场耦合计算材料高温响应时，合理确定材料宏观性能随温度的变化至关重要。 |

| The paper aims to The research on the difference of the response of low density carbon / phenolic composite in different ground heating experiments can guide the high temperature response analysis of the material in practical application environment. The single side radiation heating experiment of low density carbon fiber/phenolic composites under thermal flux 400 kW/m2 by quartz lamp was carried out. The temperature time histories of the samples at different positions during heating were measured by a thermocouple temperature measuring system. The ablation morphologies and microstructure evolvement of the samples were observed. The experiment results were also compared with that obtained by radiation heating experiment with thermal flux 464 kW/m2 by ceramic plate heated oxygen-acetylene. The finite element method was used to analyze the heat and mass transfer multi-field coupling process. For radiation heating of quartz lamp, the inflection points of temperature response occurred in turn when the temperature of measuring point rose to nearly 200 ℃. Due to the different radiation heat sources with different radiation bands, the absorbed and emitted thermal energy was different from the low density carbon fiber/phenolic composites. As for the short heating time, the increasing temperature velocity of the composites heated by ceramic plate radiation using oxygen-acetylene was faster than that of quartz lamp radiation heating experiment. On the contrary, the phenomenon was just the opposite of the long heating time. In calculating the high temperature response of materials using heat and mass transfer multi-field coupling analysis method, it is essential to determine the change of macroscopic properties of materials with temperature. |
