Ballistic performance of protective woven fabrics relies on the selection of fibres and construction of fabrics, but the development of new fibres takes time and advancement in body armour is required to provide improved protection. In order to make full use of the existing high performance fibres such as the aramid and ultra-high molecular weight polyethylene (UHMWPE) fibres, this chapter reports on the effect of yarn gripping, a measure to increase the inter-yarn friction, on the ballistic performance. Numerical and experimental approaches were employed in the study, and the results showed that increase in yarn gripping improves the impact energy absorption to a significant extent. A 25% increase in energy absorption by the fabric with enhanced yarn gripping was witnessed throughout the experiment. It was also noted that too much yarn gripping leads to less energy absorption.
