The present work aims to present some results obtained through ballistic tests performed in multilayer armor systems. Following the specifications of the American Standard NIJ 0101.04, tests were carried out using 7.62 x 51 mm caliber ammunition, which has velocity above 800 m/s. The multilayer armoring used has a hexagonal ceramic insert, followed by an epoxy matrix composite layer reinforced with fibers and mallow and jute fabric, and a third layer composed of a 5052 H34 aluminum plate. The data obtained from the ballistic test were associated with its dynamic behavior using the shock impedance method. The results showed that the high impedance of the ceramic was responsible for the absorption around 65% of the kinetic energy of the projectile. The composites reinforced with fibers and fabrics of mallow and jute, according to the absorbed energy and shock impedance, demonstrated promising applications related to ballistic protection.
