摘要
以舰用轻型复合装甲研究为背景,针对不同纤维增强种类(包括玻纤织物 C400、C200、SW220 和芳纶纤维织物T750)以及不同面密度层合板结构,在6.2 g刚性微曲面柱形弹弹道冲击下的防护能力展开实验研究,着重讨论了层合板结构弹道冲击下破坏模式、弹体初始侵彻速度及面密度与抗弹能力和抗弹效率之间的关系,认为不同的破坏模式体现了不同的吸能特性和纤维失效机理.
On the background of light armor system for warship, the experimental researches for resistance characteristic of fiberglass(C400, C200 and SW2200)and aramid (T750) woven reinforced laminates with differentthickness under ballistic impact are done and the projectiles used in this work are 6.2 grigid column with tiny curve surface. At the same time, the laminate′sdeformation model perforated, the relation between the initial velocity and the ballistic resistance efficiency for laminates are discussed, and the conclusion that different deformation model represents different characteristic of energy-absorption and fiber failureare also given.
