The invention relates to a multi-layer flexible composite spacecraft thermal control assembly and a preparation method thereof. The thermal control assembly comprises N layers of metal-plated flexible high-reflection polymer materials, N-1 layers of polyester nets and VO2 flexible films. A spacecraft structure faces outwards, a first layer of metal-plated flexible high-reflection polymer material, a first layer of polyester net, a second layer of metal-plated flexible high-reflection polymer material and a second layer of polyester net are sequentially arranged in an alternating mode till an (N-1) th layer of metal-plated flexible high-reflection polymer material and an (N-1) th layer of polyester net, finally an Nth layer of metal-plated flexible high-reflection polymer material is arranged, and a third layer of metal-plated flexible high-reflection polymer material is arranged. The Nth metal layer plated with the metal flexible high-reflection polymer material is located on the outermost side, and the other side of the metal layer is plated with a VO2 flexible thin film.

    本发明涉及一种多层柔性复合航天器热控组件及其制备方法,热控组件包括N层镀金属柔性高反射聚合物材料、N‑1层涤纶网、VO2柔性薄膜;航天器结构向外,依次布置第1层镀金属柔性高反射聚合物材料、第1层涤纶网、第2层镀金属柔性高反射聚合物材料、第2层涤纶网,如此交替,直到第N‑1层镀金属柔性高反射聚合物材料、第N‑1层涤纶网,最后布置第N层镀金属柔性高反射聚合物材料,第N层镀金属柔性高反射聚合物材料的金属层位于最外侧,金属层的另一侧镀VO2柔性薄膜。
