Aspects of Ballistic Panels Made of Endumax XF33, Tested Against Different Projectiles

This paper presents an experimental study for hard plates made of Endumax XF33– a UHMWPE ultra high molecular weight polyethylene. There are tested two plates with 68 layers and 135 layers, respectively. The objective of this research was to test different ammunitions (9x19 mm parabellum FMJ lead core, .44 magnum SJSP, 7.62x39 FMJ, 7.62x51 FMJ), and to investigate how the obtained values of BFD are positioned in relation to the limit of 44 mm, mentioned in Ballistic Resistance of Personal Body Armor NIJ Standard–0101.07. The projectile 7.62x39 produced a closer BFD to 44 mm (43 mm). For this threat, the author recommendations are to have a larger statistical population resulted from more numerous hits and or to add layer to this initial plate of 135 layers of Endumax XF33.
