摘要/Abstract

摘要： 对气凝胶分别与防弹纤维、SiC/Al复合材料和陶瓷组成的复合靶板进行靶试试验，研究气凝胶作为夹层时复合结构的抗弹性能。结果表明：当防弹纤维后面加上气凝胶夹层后，强度较低的气凝胶夹层使防弹纤维面板的变形有了很大的扩展空间，复合靶板吸收弹头动能的能力大幅提高，同时可以有效防止弹头的非贯穿性伤害。SiC/Al复合材料后面加上气凝胶夹层后，复合靶板的抗弹性能提高不明显，但可以大幅提高复合材料受到冲击后的完整性。当气凝胶作为夹层放置在陶瓷面板后面时，陶瓷面板由于没有足够的支撑作用而发生弯曲破坏，反而导致整个复合结构的防弹能力降低。

Abstract: The composite targets made of bulletproof fibers，SiC/Al composite material and ceramics in which the aerogel is an interlayer were tested, and the anti-bullet performance of composite structure with aerogel interlayer were studied. The results show that, when the aerogel is combined with bulletproof fibers, the aerogel interlayer could improve the anti-bullet performance of composite target because the deformation of bulletproof fibers is greater due to the low strength of aerogel interlayer. Thus the energy absorption capacity of composite targets improves significantly, and the non-penetrability damage of projectile can also be prevented. When the aerogel is combined with SiC/Al composite material, the anti-bullet performance of composite target improves slightly. The aerogel interlayer could improve the integrality of composite material faceplate after ballistic experiment obviously. When aerogel is combined with ceramics, ceramic faceplate may be bent due to the insufficient support of the aerogel interlayer, resulting in the decrease in the anti-bullet performance of composite target.
