NOVELTY - A composite material comprises a polyester resin functionalized with graphene oxide and reinforced with natural fibers. USE - Composite material used for layer of ballistic armor for protection against rifle fire with 7.62 mm or 5.56 mm caliber ammunition (claimed) in personal vests and military vehicles. ADVANTAGE - The composite material prevents against rifle shots with high impact ammunition and captures ceramic and projectile fragments resulting from the frontal impact. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of the composite material, which involves accommodating layers of carnauba fibers, in a continuous and aligned, corresponding to the desired proportion of 40 vol.% within a suitable metallic mold and adding graphene oxide-functionalized polyester resin and a fluid, and capping the mold.
