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。
The composite targets made of bulletproof fibers, SiC/A1 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 fi- bers, the aerogel interlayer could improve the anti-bullet performance of composite target because the de- formation of bulletproof fibers is greater due to the low strength of aerogel interlayer. Thus the energy ab- sorption capacity of composite targets improves significantly, and the non-penetrability damage of projec- tile can also be prevented. When the aerogel is combined with SiC/A1 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 ceram- ics, 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.
