The invention relates to an embedded energetic material space debris protection structure combined with an impedance mismatch effect, which is used for protecting space debris with the particle size of less than 1cm and comprises a high-impedance metal plate and energetic material blocks, and the energetic material blocks are uniformly embedded in the high-impedance metal plate at intervals. The energetic material is composed of an inert material and reactive metal particles. The protection characteristic of the high-impedance metal material is brought into full play, the impact initiation characteristic of the energetic material is introduced, and the impedance mismatch effect is generated by using the impedance difference between the high-impedance metal material and the energetic material, so that the protection effect of the protection structure is improved. The advantages of an energetic material and a high-impedance metal material are combined, and the comprehensive performance of the protection plate is remarkably improved through composite use of the two materials.

    本发明涉及一种结合阻抗失配效应的嵌入式含能材料空间碎片防护结构,用于防护粒径为1cm以下的空间碎片,包括高阻抗金属板和含能材料块,所述含能材料块均匀间隔嵌入在高阻抗金属板内部,所述含能材料由惰性材料和反应金属颗粒组成。本发明不仅充分发挥了高阻抗金属材料的防护特性,还引入了含能材料的冲击起爆特性,并利用了二者的阻抗差异,产生了阻抗失配效应,从而提高了防护结构的防护效果。本发明结合了含能材料与高阻抗金属材料的优势,通过两种材料的复合使用,显著提升了防护板的综合性能。
