| 摘 要： | 通过地面模拟空间环境质子辐照条件(质子能量Ep=150keV,束流密度A=2.0×1012cm-2·s-1,辐照剂量范围Φ=(0～5.0)×1016cm-2;真空度10-6Pa,环境温度120 K),研究了不同辐照剂量下环氧树脂浇注体648和TDE-85的质量损失、弯曲强度和表面相糙度的变化.试验结果表明,随着辐照剂量的增加,质量损失呈现先加速递增后趋于平缓的趋势;648的弯曲强度呈单边下降趋势,TDE-85的弯曲强度呈现先上升后下降的趋势,树脂表面产生了碳化效应,表面粗糙度发生了不同程度的变化.

| Abstract: | Mass lose, bending strength and surface coarseness of epoxy resin 648 and TDE-85 with different irradiation dosages are studied by simulating proton irradiation conditions of space environment on the ground, that is proton energy Ep=150 keV, beam density A=2.0×1012 cm-2s-1, irradiation dosage range Φ=(0~5.0)×1016 cm-2, vacuum degree 10-6 Pa, and environment temperature 120 K. The test results show that with the increase of irradiation dosage, mass lose tends to increase sharply at first and then to grow gently, bending strength of epoxy resin 648 decreases monotonically, bending strength of TDE-85 increases firstly and then decreases, the resin surface shows carbonization effects and surface coarseness changes to some extents. |
