In this paper, a Hybrid polymer composite is developed which has light-weight to high strength ratio. Due to this characteristic of polymer-matrix composite, it starts replacing the metal-matrix composite in a variety of domains, including sports equipment, drugs vehicles, automobile, aerospace industries, railways, etc. A hybrid polymer composite is developed by employing hand layup method and material used is epoxy as matrix material incorporated with nano-grapheneoxide, kevlar fiber and banana fiber. Composites are made by incorporating different wt.% of nano-grapheneoxide i.e., 0, 0.25, 0.50, 0.75 and 1 wt.%. Mechanical characterization of all the samples is done and its highest values found to be 130.75, 218.17, 29.28 MPa and 72.58 for tensile strength, flexural strength, inter-laminar shear stress and hardness respectively. All these values are obtained at 0.5 wt.% of nano-grapheneoxide. The highest impact strength was found to be 370.2 J/m at 0.25 wt.% of nano-grapheneoxide. FESEM test was conducted to check the homogeneity of the composites.
