| Abstract Scope |
Increasing numbers of violence and armed conflict make efficient protection systems necessary, and one of the solutions that has yielded advantageous results is the multilayer armoring system (MAS). MAS use lighter, cheaper materials. This type of shield consists of three layers. The first was a ceramic material, which has the function of fragmenting the tip of the projectile and absorb most of the energy of ballistic impact. The second is composed of an epoxy composite reinforced with natural fibers, in order to absorb the cloud of fragments of the ceramic layer and to absorb the remaining energy. The objective was to analyze the behavior of the epoxy matrix composite reinforced with buriti fabric in the contents of 10, 20 and 30 vol%. Ballistic tests were carried out with 7.62x51 mm ammunition. The data were statistically treated by the ANOVA and met the NIJ standard, regardless of the percentage of reinforcement. |
