Abstract

Bullet-resistance and weight are important features of anti ballistic materials. Kevlar fibers are the widest reinforcement material for military and civil systems due to their excellent impact resistance and high strength-to-weight ratio. Kevlar fibre based composites are used for designing personal helmets and body armor to effectively stop both fragmentation and bullets. In this report, the influences of fabrics and technological factors on the properties of the composite made of kevlar and PVB/PF resin were studied. The results showed the composite sample with desired properties could be achieved by using the Kevlar fabric K-129 with the weight ratio of fabric:resin = 0.8:0.2 under the processing conditions: temperature-150 oC, pressing pressure-150 kg/cm2, pressing period-45 minutes. The tensile strength of composite materials is 743.52 Mpa. The composite samples in the shape of plate and helmet passed the ballistic tests with 17 grains (1.1 grams) of Fragment Simulating Projectiles (FSPs) at a speed of 438.92 m/s.
