Ballistic experiments on the mechanism of protective layer against domino effect caused by projectiles
The mechanism of protective layer against the domino effect caused by high velocity and low mass projectiles was investigated using ballistic experiments, under various values of thickness, surface density, fabric structure, and impact velocity. The results showed that unit absorption energy generally decreased and then increased with thickness and surface density. The critical value of thickness existed, the highest absorption was demonstrated in UD composite, and the back convex reached the maximum when impact velocity reached the ballistic limitation. Stretching fracture of fiber was the major way of energy absorption. Finally, four layers were designed for the protective layer. (C) 2015 Elsevier Ltd. All rights reserved.
