The invention discloses an energetic wave impedance gradient material for space debris superspeed impact protection, and the energetic wave impedance gradient material is characterized in that an energetic active material layer is added as a component material on the basis of an inert metal component material. In the invention, through wave impedance gradient matching design and impact initiation threshold adjustment, the inert metal material and the energy-containing active material are combined according to a certain rule, so that the novel composite material has both wave impedance gradient and impact initiation reaction under ultra-high-speed impact, and the two effects jointly promote the crushing and dispersion of bullets; the novel high-performance space debris protection material integrates two protection mechanisms of wave impedance gradient and impact initiation reaction, has higher protection capability under the same mass, can be directly applied to space debris protection design of manned spacecrafts and high-value satellites, and has wide application prospects. And long-life and high-reliability operation of on-orbit spacecrafts in China is ensured.

    本发明公开了一种用于空间碎片超高速撞击防护的含能波阻抗梯度材料,所述含能波阻抗梯度材料在惰性金属组分材料的基础上,添加含能活性材料层作为组份材料。本发明中,通过波阻抗梯度匹配设计、冲击起爆阈值调节,将惰性金属材料与含能活性材料按照一定规律结合,使得新型复合材料在超高速撞击下既存在波阻抗梯度,也存在冲击起爆反应,两种作用共同促进弹丸的破碎、分散,从而实现防护能力的进一步提升,综合了波阻抗梯度与冲击起爆反应两种防护机理的新型高性能空间碎片防护材料,相同质量下具有更高的防护能力,可直应用于载人航天器及高价值卫星的空间碎片防护设计,确保我国在轨航天器长寿命、高可靠运行。
