Abstract :Recent armor studies generally rely on improving the single-shot capabilities of ceramic armors. In multi-shot studies, ballistics tests assume that there is a certain distribution, so these successive shots were not made from exact same point. With these shots, thus, the armor completely loses its effectiveness. In this study, the ballistic performance of damaged and undamaged free particle armor system in multiple hits from exact same and different points was experimentally investigated. The new armor system, consisting Al2O3 free ceramic balls, tested with 9 mm FMJ and 7.62 mm API ammunition. This armor system prevented perforation in multi-hits from the same point, and the depth of depression in ballistic clay was 9.42 mm and bullet deviation in trajectory was 27 mm. In the shots with dispersion, depression depth was limited to 3.52 mm and deviation increased with each shot. As a result, it has been found that the free particle armor system performs more ballistic efficiency than conventional armors even in the most challenging conditions. The ceramic balls, being more irregularly and densely spaced with each shot, increase the likelihood of the bullet hitting at larger angles and increase ricochet in direct proportion.
