脉冲软X射线辐射下复合材料的辐射特性实验研究

摘要

The blow-off impulse of composites induced by pulsed soft X-ray was studied on "Qiang guang-I" pulsed accelerator. A new impulse probe designed by NINT was used to measure the blow-off impulse of four kinds of materials, which are Paint A , Paint B, Ly-12 aluminum and glass fibre reinforced plastic(GFRP) respectively. The results show that compared with paint A, Ly-12 aluminum and GFRP, paint B has better anti-radiation performance. In the range of experimental energy fluence, the thermal-ablated rate induced by pulsed soft x-ray of paint B is only one tenth of paint A and so it is concluded that paint B may be one of the best coating materials for the space vehicle.%采用自行研制的微型红外通光测试系统,对三种复合材料和硬铝在脉冲软X射线辐射下的喷射冲量进行了实验测量研究.结果表明:涂层B较涂层A、玻璃钢和硬铝具有更好的抗脉冲辐射性能;在实验能注量范围内涂层B的烧蚀率只是涂层A的十分之一,是硬铝的三分之一.可以断定,涂层B是空间飞行器的最好防护层材料之一.
