Effect of Resin on Laminate Ballistic Performance Subjected to Small and Large Calibre Projectiles

Abstract

Polymer composite laminates has got crucial role to play in reduction of armour weight due to their high specific energy absorption capabilities. The role of resin in composite armour is paramount in impact energy absorption. In the present study, ballistic performances of E-glass/phenolic and E-glass/epoxy laminates were compared against small arms and large calibre ammunition. The laminates with varying thickness were fabricated through hot pressing method and were evaluated against small and large calibre projectiles. E-glass/phenolic laminate showed 30 % more energy absorption than Eglass/ epoxy laminate. Failure behaviour of laminates were studied and characterized based on delamination and fiber stretching.
