| 摘 要： | 为研究铝蜂窝夹芯三明治结构的弹道防护特性，设计并实施了一系列速度在100~250 m/s之间的弹道冲击实验. 研究了在不同冲击速度、面板厚度、芯层密度和弹丸头部形状等条件下，该结构的能量吸收特性和弹道极限. 结果表明，铝蜂窝夹芯能有效提高三明治板的抗弹能力，并且对高速弹丸防护能力的提高作用更加显著. 在弹速相同的条件下，结构对平头弹丸的能量吸收低于圆头和尖头弹丸. |

| Abstract: | To study the protection properties of sandwich panels with aluminum honeycomb core, ballistic impact tests were carried out. Effects of several key parameters, such as impact velocity, skin thickness, core density and projectile shapes, on the energy absorption and the ballistic limit were analyzed. The results showed that the aluminum honeycomb core could improve the ballistic limit of sandwich panels effectively and the protection from higher impact velocity. Moreover, under the same impact velocity, the energy absorption for the flat-nosed projectiles was found lower than that for the hemispherical and conical-nosed projectile. |
| Keywords: | aluminum honeycomb sandwich panels ballistic limits energy absorption |
