From the literature it is seen that graphene oxide nano filler possess exceptional mechanical properties and it is being used for enhancing mechanical properties in polymer composite. The effect of inclusion of graphene oxide nano filler on dynamic properties in fiber reinforced polymer composite has not been fully investigated. The objective of this experimental work is to investigate the dynamic properties of graphene oxide based nano-modified symmetric Glass/Carbon interlayer hybrid laminates. Ultra-sonification has been used for dispersing graphene oxide (0.5%wt) nano filler into the epoxy. The unidirectional carbon fibers are placed into the composite laminate at various stacking sequence. The modal parameters like frequency, mode shape and damping ratio were determined experimentally using traditional ‘strike method’ using FFT analyzer and Data Acquisition System. Experimental modal analysis of the composite laminates was conducted for fiber orientations of 45 and for two boundary conditions ( ie F-F-F-F and C-F-F-F). The effect of hybridization using graphene oxide nano filler in symmetric glass/carbon interlayer composite on frequency and modal damping are discussed in this paper. This research work provides basic understanding of the dynamic behavior of interlayer hybrid composites with incorporation of Graphene oxide.
