Fabrication, characterization and some mechanical properties of graphene–kevlar epoxy hybrid

The present study aims to investigate the aptitude of graphene inclusion effects on impact strength and hardness characteristics of kevlar fiber reinforced hybrid composites. There is a requisite for emerging new industrial procedures to fabricate polymer improved with nanomaterial for requests where weight, stiffness and strength. Graphene was equipped by "oxidation of graphite" fragments and characterized by microwave techniques. Graphene and Kevlar fibers independently bargain a very extensive field of applications because of their various mechanical properties. Graphene/ kevlar the hybrid laminates epoxy composite were made-up by a dry hand layup technique with 25% volume fractions. "Impact strength (I.S) and hardness shore (D)" were examined in accordance with ASTM standards. Structure and morphology were tested using XRD and FESEM. The x-ray spectrum shows that the pattern of the particles formed have peak (001), and rang of crystalline size between (17-6 nm). The test results show a considerable improvement in impact strength and hardness values with an increase of graphene/kevlar content in the composite increased. Interfacial surface area treatment of fiber reinforcements with nanoparticles, on the other influence could expand in possessions of" laminated composites", even as interfacial adhesion.
