Abstract

Space radiation has been well-known as the main health hazard to crews involved in manned space explorations. Two kinds of hydrogenous-rich composites are developed through compressing molding under high-temperature processing techniques for shielding space radiation. Beams of 80~400 MeV/n 12C of the Heavy Ion Research Facility in Lanzhou are used to test the shielding properties of the new composites. Experimental results show that the composite with more hydrogen content has higher shielding ability for 80 and 400 MeV/n 12C particles. Meanwhile, the addition of boron has no obvious effect on improving the shielding performance of the composite. Monte Carlo radiation transport codes were used to assess the shielding performance of composite in real space radiation. The simulation results show that hydrogenous-rich composite has significant advantage in space radiation shielding compared with traditional aluminum.

研制的含氢复合材料屏蔽性能的实验与仿真研究

众所周知，空间辐射是载人航天探索人员的主要健康危害。采用高温加工技术，通过压缩成型制备了两种屏蔽空间辐射的富氢复合材料。利用兰州重离子研究中心80~ 400mev /n 12C束流对复合材料的屏蔽性能进行了测试。实验结果表明，含氢量较高的复合材料对80和400 MeV/n的12C粒子具有较高的屏蔽能力。同时，硼的加入对提高复合材料的屏蔽性能没有明显的作用。采用蒙特卡罗辐射输运码对复合材料在实际空间辐射中的屏蔽性能进行了评价。仿真结果表明，与传统铝相比，富氢复合材料在空间辐射屏蔽方面具有显著优势。
