This 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 armor used has a hexagonal ceramic insert (alumina 4% doped niobium pentoxide), a second layer of fique fabric reinforcing epoxy matrix composite, and a 5052 H34 aluminum alloy plate as the third layer. The use of polymeric composites reinforced with natural fibers as a substitute for aramid fibers is of great interest because, in addition to performing the same function in the armor system, which have a much lower market value. With the results obtained from the ballistic test, the values were associated with their dynamic behavior using the impedance matching method.
