Influence of graphene oxide nanoparticle and aluminium powder in carbon fiber epoxy composite was analysed in this experimental analysis. Three different compositions were developed based on the following combinations: Specimen 1 (Graphene oxide 3% − 15 gm and Aluminium 1.5% − 7.5 gm), Specimen 2 (Graphene oxide 6% − 30 gm and Aluminium 3% − 15 gm) and Specimen 3 (Graphene oxide 9% − 45 gm and Aluminium 4.5% − 22.5gm). The percentage of graphene oxide and aluminium are chosen depending upon the weight of resin (500 g) used for fabrication. The mechanical and thermal behavior of the developed composites were tested based on ASTM standards. Incorporation of 3 wt% of graphene oxide nano particle and 1.5 wt% of aluminium powder shows the best mechanical and thermal properties. Finite element analysis was performed to compare the static properties of aluminium alloy rim and the developed CFRP rim using ANSYS Workbench 18.2, infers that the CFRP rim had very high strength to weight ratio or specific stiffness than aluminium alloy rim.
