The invention relates to the technical field of spacecraft protection, in particular to a frame honeycomb structure, a honeycomb sandwich structure and a fiber filling type protection structure. The frame honeycomb structure comprises a plurality of honeycomb core grids; a rectangular hole penetrating through the wall surface is formed in the central position of each wall surface of the honeycombcore grid; and the edges of the rectangular holes are parallel to the edges of the wall surface to form a frame type wall surface with a symmetrical structure, so that the problem that the honeycomb structure is unfavorable for fragment cloud diffusion due to a channel effect can be effectively solved, and meanwhile, the honeycomb structure has relatively high structural strength. According to thehoneycomb sandwich structure, the honeycomb core adopts a frame honeycomb structure, so that the problem that the honeycomb structure is unfavorable for fragment cloud diffusion due to a channel effect can be effectively solved while the corresponding structural strength is ensured, and better supporting and protecting effects are achieved. According to the fiber filling type protection structure, the fiber filling layer is supported and fixed through the frame honeycomb structure, the better supporting and protection effects are achieved, and the additional weight of the fiber filling type protection structure can be reduced by at least 50%.
本发明涉及航天器防护技术领域,尤其涉及一种框架蜂窝结构、蜂窝夹层结构及纤维填充式防护构型。框架蜂窝结构包括多个蜂窝芯格,所述蜂窝芯格的每个壁面的中心位置均具有一个贯穿所述壁面的矩形孔,所述矩形孔的边与所述壁面的边平行设置,形成结构对称的框架式壁面,能够有效解决蜂窝结构因沟道效应而不利碎片云扩散的问题,同时使蜂窝结构具有相对高的结构强度。蜂窝夹层结构,其蜂窝芯使用框架蜂窝结构,在保证相应结构强度的同时,能够有效解决蜂窝结构因沟道效应而不利碎片云扩散的问题,起到更好的支撑和防护效果。纤维填充式防护构型利用框架蜂窝结构对纤维填充层进行支撑和固定,起到更好的支撑和防护效果,并至少可减轻其附加重量50%。
