摘要 以Kevlar纤维增强层合材料为对象,通过系列弹道冲击实验,研究了层合板的抗弹性能,着重分析了弹头、纤维铺设方式以及板厚等因素对靶板抗侵彻能力的影响,同时对靶板的破坏模式也作了必要的讨论。此外,还通过一种工程近似方法,分析了不同弹头弹丸的弹道极限速度,预测值与实验值具有良好的一致性。 The ballistic resistance of Kevlar laminates is investigated by a series of ballistic impact tests. The effects of projectile noses, fiber orientation and target thickness on the perforation of Kevlar laminates are discussed. The failure modes are also analyzed. Ballistic limits of projectiles with different noses are predicted by an engineering analytical method. The results are in good agreement with the experiments.
