▎ 摘　　要

NOVELTY - A composition is obtained from functionalization of epoxy resin by drying 50 ml graphene oxide at 4.02 mg/ml in a vacuum chamber, dissolving in 100 ml isopropyl alcohol, ultrasonically-processing for 1 hour until reaching a colloidal suspension and mixing the solution with the epoxy resin under mechanical agitation for 10 minutes. USE - Composition used for producing composite material for multilayer ballistic shields for protecting against rifle shots with ammunition of high impact power (all claimed) to improve defense and security of civil and military. ADVANTAGE - The composition provides a composite with graphene oxide having excellent homogeneity and continuity and improving dissipation of impact energy of the projectile. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite material, which involves preparing yarn fibers for functionalization with graphene oxide, functionalizing the yarn fibers, preparing the amount of fibers to 30 vol.% of the composite, functionalizing the epoxy resin to produce the composite, pouring the epoxy/graphene oxide functionalized resin into the metal matrix until the bottom is completely wet, adding the fibers functionalized with graphene oxide with the epoxy/graphene oxide resin, ensuring the fibers wetted by the resin, pressing the mixture at room temperature using a hydraulic press with 5 tons of force for 24 hours, demolding a composite plate and assembling a multilayer ballistic armor.
