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。
A large number of space debris accumulated in space for human space activities is a serious threat to the safety of orbiting spacecraft. It is urgent to develop a new material protection structure with excellent protection performance and to study the impact characteristics of the filled hollow sphere / aluminum matrix Whipple structure , To obtain relevant impact damage data, to compare with Whipple protective structures filled with solid aluminum panels and to evaluate the feasibility of hollow sphere / aluminum matrix composites as a spacecraft shielding material.
