Design of transparent armor materials for observation and detection device

设计和制作基于镁铝尖晶石(MgAlO)的透明装甲材料,由迎弹面、缓冲层、防飞溅层及聚合物粘接层组成。研究装甲面密度、厚度与弹头剩余速度间关系。用TFCalc光学薄膜设计软件研究增透膜系对装甲材料透光性能的影响。结果表明:基于镁铝尖晶石(MgAl2O4)的抗53式7.62 mm穿甲燃烧弹装甲材料面密度低于75 kg/m,厚度低于30 mm。加入增透膜系可实现双波段高透光率,材料在380~780 nm和1 064 nm波段透光率大于90%。试验验证透明装甲样品,抗弹性能和透光率测试结果与仿真结果吻合。

A transparent armor material based on magnesium aluminum spinel(MgAl2O4)was designed and fabricated,which consisted of projectile facing surface,buffer layer,anti splash layer and polymer bonding layers. The relationship between the area density and thickness of armor and the remaining velocity of bullet was studied. The results show that the area density of the anti-7.62 mm armor piercing bullet material based on spinel is less than 75 kg/m2and the thickness is less than 30 mm. In addition,the effect of the antireflective film system on the light transmission performance of armor materials was studied by using TFCalc optical film design software. The dual-band high transmittance can be achieved with the addition of the antireflective film system,and the transmittance of the material is not less than 90% in the band ranging from 380 nm to 780 nm and the band of1 064 nm. Transparent armor samples were made for experimental verification,and the measured results of bullet resistance and transmittance are in good agreement with the simulation ones.
