摘要: 纤维增强复合材料由于具有较低的面密度和较大的比吸收能,广泛应用在个体防护领域,而其中采用的高强纤维的断裂是最主要的吸能方式。以前的研究主要集中在弹道实验后对破坏模式的观察,为此采用有限元方法模拟了Twaron○R纤维束受到弹体侵彻的破坏过程,并与前人的实验结果进行比较,具有高度的相似性,进一步说明了纤维束的吸能机制,对软体结构防护系统的设计具有一定的指导意义。

Abstract: Having lower area density and high specific energy absorption(SEA),fiber-reinforced composites are widely used in the area of personal armor.And the breakage of fibers in composites is the main mode of energy absorption.Previous researches were focused on the observing of the damage mode after a ballistic test.This paper simulated Twaron~D○R fiber struck by the steel projectile with finite element analysis(FEA).The result is compared with that of previous experiment and found that they are quite similar.In addition,fiber energy absorption principle was further explained.This research result may serve as a guide in the design of personal armors.
