ABSTRACT

In this paper, a review of natural fibers composites used in protective armors for ballistic applications like bulletproof vests is presented. It seeks to compile the results and establish natural fiber composites as an alternative to absolute synthetic composites used for the same application. The review assesses the latest articles under two categories viz. only natural fibers and hybrid composites with natural and synthetic fibers. It covers a range of fibers from flax, basalt, curaua, kenaf, aramid, jute, coir, and hemp. The study systematically classifies the composites based on the ballistic limit they exhibit and the back face signature measured during standardized ballistic testing. In accordance with the results, the findings are compared against standard materials such as Kevlar used in ballistic armors. The hybrid composites are seen to present superior properties in comparison to plain natural fiber composites. Natural fibers provide an ecological and economical alternative to existing composites. The review shows promising results and immense future scope for natural fibers in the area of ballistic applications and they must be actively considered for replacing synthetic fibers in armor.

摘要

本文综述了用于防弹应用（如防弹背心）的防护装甲的天然纤维复合材料。它试图汇总结果并建立天然纤维复合材料作为用于相同应用的绝对合成复合材料的替代品。该评论评估了两类最新文章，即。只有天然纤维和具有天然和合成纤维的混合复合材料。它涵盖了一系列纤维，包括亚麻、玄武岩、curaua、洋麻、芳纶、黄麻、椰壳纤维和大麻。该研究根据复合材料表现出的弹道极限和标准化弹道测试期间测量的背面特征对复合材料进行系统分类。根据结果​​，将这些发现与标准材料（例如用于防弹装甲的凯夫拉纤维）进行了比较。与普通天然纤维复合材料相比，混合复合材料被认为具有优越的性能。天然纤维为现有复合材料提供了一种生态和经济的替代品。审查表明天然纤维在弹道应用领域的前景广阔，未来前景广阔，必须积极考虑将它们用于替代装甲中的合成纤维。
