Curved geometry in unidirectional CFRP (UD-CFRP) demands ideal shape optimization to attain superior performance while maintaining the desired high strength to weight ratio. Herein, the effect of graphene oxide (GO) as the potential filler to improve the mechanical and thermal properties of flat and curved specimens of UD-CFRP was investigated. The GO was synthesized using Hummer's method and introduced in the epoxy resin by wet transfer technique. Three-point and four-point bending analysis of UD-CFRP showed maximum flexural strength and modulus at 0.3 wt% GO addition in UD-CFRP. The improved interfacial adhesion of 0.3 wt% GO incorporated UD-CFRP was realized by calculating storage modulus, reinforcement efficiency factor (r), C-factor, adhesion factor, cross-linking density, and glass transition temperature (T-g) from dynamic mechanical analyzer. Fracture analysis by scanning electron microscope showed the superior interlocking in carbon fiber, and epoxy polymer at 0.3 wt% GO addition.
