Fiber Reinforced Polymer Composite for Bullet Proof Application
Fiber reinforced polymer composites have historically been used and researched for their impact resistant properties. In this research the impact resistance of Kevlar reinforced thermoplastic composite was investigated for in-field performance. Hundred percent Kevlar unidirectional fabric was first manufactured as pre-preg and then using solvent, high pressure and temperature fused to manufacture bullet proof torso, front panel. Graphite powder was added for additional hardness and impact resistance making composite a hybrid composite. This manufactured composite torso panel was found to be roughly five times lighter than commercial bullet proof vests available in market. In field testing for impact resistance was conducted using 9 mm pistol, total four aims were made from five meters to twenty meters in increments of five. All bullets were successfully stopped and captured by armor panel.
