The invention discloses a space debris protection structure for a spacecraft and a preparation method thereof.The space debris protection structure comprises a protection layer structure, the protection layer structure comprises at least three protection layer combinations which are combined and fixed, and each protection layer combination comprises a buffer layer and a protection layer located on the outer side of the buffer layer; the buffer layer has a folded state and an unfolded state. Compared with a traditional basalt-polyurethane foam composite protection structure, the space debris protection structure provided by the invention has the advantages that the defense capability to space debris can be improved, the protection performance of the space debris protection structure is improved by 10%-15%, the space debris protection structure has the characteristics of light weight, small size, long service cycle and good heat insulation and protection effects, the weight of the space debris protection structure is reduced by 25%-30% compared with a three-layer whipple structure with the same protection efficiency, and the service life of the space debris protection structure is prolonged. The size is reduced by 60%-70%, and the device can serve for 5 years in an on-
本发明公开一种用于航天器的空间碎片防护结构及其制备方法,所述空间碎片防护结构包含防护层结构,所述防护层结构包含至少三组结合固定的防护层组合,所述防护层组合包含缓冲层以及位于缓冲层外侧的防护层,所述缓冲层包含收纳状态和展开状态。本发明提供的空间碎片防护结构可提高对空间碎片的防御能力,与传统的玄武岩‑聚氨酯泡沫复合防护结构相比,其防护性能提升10%~15%,并且兼具重量轻、体积小、服役周期长、隔防热效果好的特点,与同等防护效能的三层whipple结构相比减重25%~30%,体积减少60%~70%,可在轨空间服役5年。
