▎ 摘　　要

NOVELTY - Composite material includes epoxy resin functionalized with graphene oxide (GO) and reinforced with curau fibers (Ananas erectifolius) also functionalized with GO, ferrocene (FC)/GO, both by the process of immersion in suspension of GO in alcohol. USE - Composite material used in ballistic armor, especially multilayer ballistic armor for protection against high-velocity rifle firing with 7.62 mm or 5.56 mm ammunition and ballistic armor system that optimizes tier III-A threat vests for tier III threat vests (all claimed). ADVANTAGE - The composite enables to replace much more expensive and denser synthetic materials currently used in the armed forces around the world, such as the aramid fiber fabrics. The immersion of fibers in suspension of GO in alcohol prevent degradation and improve the properties of curaua fibers. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing composite material, which involves using a rectangular metal mold that has dimensions of 1 cm thick by 15 cm long and 12 cm wide, applying silicone grease release agent to the inner surface of the mold, accomodating desired proportion of 30 vol.% FC/GO fibers within a suitable metal mold, adding epoxy resin functionalized with GO, epoxy/GO in fuild state, closing the mold with the die cap, and applying a compression load of 5 mega Pascals at room temperature for a period of 24 hours on the capped mold, already filled with curaua fibers functionalized with graphene oxide and epoxy/GO resin.
