摘要
针对人类航天活动在空间中积累的大量空间碎片严重威胁在轨运行航天器安全,急需开发具有优良防护性能的新材料防护结构问题,初步研究填充空心球/铝基复合材料Whipple防护结构的撞击特性,获得相关撞击损伤数据,与填充实心铝板的Whipple防护结构进行对比,并评估空心球/铝基复合材料作为一种航天器防护材料的可行性。
Plenty of space debris are produced by human in space. They are a threat to the normal operation of inorbit spacecrafts. So, it is necessary to develop a new material shielding structure with a good protection performance. Here, the impact properties of a cenosphere/aluminum matrix composite stuffed shield were investigated. Then, some data related to impact damage were obtained, and they were compared with those of a whipple protection structuve using solid aluminum stuffed shield. On this basis, the feasibility of cenosphere/aluminum matrix composite material as a protection material for spacecraft was evaluated.
