The invention provides a prefabricated body structure and a satellite, the prefabricated body structure is made of a carbon fiber material, the prefabricated body structure comprises a first tubular shell, a second tubular shell, a first circular ring and a second circular ring, the second tubular shell sleeves the first tubular shell, and the second tubular shell and the first tubular shell are coaxially arranged; the first circular ring and the second circular ring are sequentially arranged on the first tubular shell in a sleeving mode in the axial direction of the first tubular shell. Openings in the two ends of the first tubular shell are sewn to the inner ring of the first circular ring and the inner ring of the second circular ring respectively, the two ends of the second tubular shell are sewn to the side face of the first circular ring and the side face of the second circular ring respectively, and mounting process holes are formed in the first circular ring and the second circular ring respectively. According to the prefabricated body structure, weight reduction is facilitated, and the structural strength and stability can be effectively guaranteed; meanwhile, light weight is effectively achieved, meanwhile, stitching of carbon fibers on the surface of the prefabricated body structure is facilitated, and the preparation difficulty of the prefabricated body structure is lowered.
本申请提供一种预制体结构及卫星,预制体结构采用碳纤维材料,预制体结构包括:第一管状壳体、第二管状壳体、第一圆环和第二圆环,第二管状壳体套设于所述第一管状壳体且与第一管状壳体同轴设置;第一圆环和第二圆环沿第一管状壳体的轴向依次套设于第一管状壳体;第一管状壳体的两端开口分别与第一圆环的内环以及第二圆环的内环缝合,第二管状壳体的两端分别与第一圆环的侧面以及第二圆环的侧面缝合,第一圆环和第二圆环上均设置有安装工艺孔。本申请提供的一种预制体结构有利于减重,可以有效保证结构强度和稳定性;同时,在有效实现轻量化的同时,便于对预制体结构表面碳纤维的缝合,降低预制体结构的制备难度。
