Effect of Amine Functionalized GO on CFRP Mechanical Properties

Bol

Fiber Reinforced Polymer (FRP) composites have been employed widely in the last ten years to create lightweight constructions, particularly under critical loading circumstances due to its high strength-to-weight ratio. However, the brittleness of the matrix materials and the inadequate adhesion at the fiber-matrix interface caused the composite structures to break early. To encounter these issues, attempts were made to reinforced functionalized graphene oxide nanosized particles at the fiber-matrix interface. So, in the present work, carbon fiber with amine functionalized Graphene Oxide (AGO) with varying content (0 wt%, 0.25 wt%, 0.5 wt% and 1 wt%) was reinforced into epoxy resin to prepare the composites samples using hand lay-up cum compression molding process. The air bubbles from the Nano resin mixture were removed using vacuum pump. The prepared samples were tested as per ASTM Standards under Tension, Bending and impact loading conditions. There is expected to enhance all the mechanical properties at particular wt. % of GO in the selected range. Further, fractography analysis of best tensile sample was analyzed using SEM to understand the failure mechanism of composites.
