| Abstract Scope |
According to the evolution of the war industry, new ballistic shielding technologies were being developed, including the Multilayer Armor System (MAS). In this work, MASs formed by ceramic tablets (Al2O3 + 4% Nb2O5) in the front layer, epoxy composites reinforced with guaruman fibers (Ischnoshiphon Koern) in the second layer and aramid fabric (kevlar ©) composing the last layer were studied. Amazonian guaruman fibers were analyzed for ballistic behavior of their composites as a second layer in MAS. The results showed that composites reinforced with guaruman meet the requirements of the NIJ-0101.05 (2000) standard with an average trauma of 27.51 mm, less than the required 44 mm. In addition to this requirement, it was identified that composites reinforced on more than one steering axis have better results in terms of their physical integrity after the ballistic test |
