Abstract:

In order to meet the requirements of performance improvement and weight reduction of flexible ballistic panels, and to optimize the structure design of flexible multi-ply ballistic materials, spacing was incorporated between the adjacent layers to study the dynamic response of the front and back layers. This research used ballistic penetration test to characterize the energy absorption capacity of fabric panels, and also made use of a finite element model to analyze the mechanisms of energy absorption. It was found from the ballistic tests that the energy absorption of the target decreases and then increases as the layer spacing widens. When a critical value is reached, the energy absorption stops increasing. The numerical predictions obtained from finite element modeling share similar trend with the experimental results. It was found that the transverse deflection and the stress distribution area of the front layer increase as the layer spacing becomes widened, whereas the magnitude of stress distribution decreases on the rear layer.

Key words: flexible body armor, ballistic material, layer spacing, anti-penetration performance, ballistic penetration
