Investigation of the Performance of a V-shaped Inner Plate Array Armor System Against 7.62 mm Caliber Bullets

Abstract

In this study, the impact resistance performance of the steel internal structure, which is fixed with screws between the front and rear plate, has a 90 degrees bent form and is placed to deflect the penetrating bullet, was measured. This article presents the ballistic performance of the designed armor system against 7.62 mm armor-piercing projectiles with a velocity of 630 to 870 +/- 10 m/s, coming at an angle of 90 degrees to the front plate. The study was carried out both experimentally and numerically. Experimental results showed that remarkable ballistic results were obtained among the investigated materials examined in 32 mm thick aluminum-steel-aluminum sheet structures. Numerical and experimental results were compared and a significant correlation was found. In addition to the ballistic performance results, the samples were examined for fracture mechanisms by scanning electron microscopy and EDS analysis.
