Abstract

A critical review on the factors affecting the impact resistance and various approaches adopted to enhance the performance of soft body armour materials is presented here.

Highlights

  • Body armour is a protective gear which is used to protect the human body against attacks of various kinds of sharp objects or projectiles

  • It is interesting to note that the experimental results of Laha et al.[45] showed that plain woven outperformed the other weaves in terms of impact resistance performance

  • Contrary to this, Sadegh and Cavallaro[54] reported that crimp imbalance in woven fabrics has a substantial effect on the Review energy absorption, stating that there exists an optimum level of crimp imbalance that would give maximum level of energy absorption for a particular threat

Introduction

Unsanhame Mawkhlieng is a doctoral candidate in Textile and Fibre Engineering at Indian Institute of Technology Delhi, India He is working in the eld of protective textiles, in 3D weaving for ballistic applications. Abhijit Majumdar is an Institute Chair Professor in Textile and Fibre Engineering at Indian Institute of Technology Delhi, India He has published 100 research papers in international refereed journals and guided nine PhD students. Second generation so body armour, prepared from nylon ak,[7,8] was introduced during the World War II It proved to be a very good barrier against munition fragments, it, failed against most of the pistol and ri e threats.
