| Abstract: |
| 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. |
