层间混杂复合材料的弹道侵彻性能研究

Study on Ballistic Penetration Property of Interply Hybrid Composite Material

结合高性能纤维材料力学性能的差异设计并制备碳纤维、对位芳纶和高强玻纤织物增强单一和厚向层间混杂防弹复合材料,进行弹道侵彻试验并表征冲击能量吸收和弹道极限指数BPI。试验表明就单一复合材料而言,Kevlar129芳纶纤维防弹性能优于S2玻璃纤维,T300-6K碳纤维相对较差,而厚向层间混杂复合材料能有效地提升三种纤维的防弹性能。在此基础上,结合复合材料在弹道侵彻下的冲击响应、破坏模式以及能量的吸收的模式对抗弹道侵彻机理进行了初步探讨。

This paper designs and prepares carbon fiber, twaron and high-strength glass fiber fabric in combination with the difference of mechanical property of high-performance fibrous materials to enhance single and normal interply hybrid bulletproof composite material, conducts ballistic penetration test and characterizes impact energy absorption and ballistic limit index BPI. The test shows that, in terms of single composite material, the bulletproof property of Kevlar129 aramid fiber is better than that of $2 glass fi ber; that of T300-6K carbon fiber is relatively poor; normal interply hybrid composite material can effectively improve the bulletproof property of these three fibers. On this basis, this paper preliminarily discus ses anti-ballistic penetration mechanism in combination with the impact response, failure mode and energy absorption mode of composite materials under ballistic impact.
