Epoxy composite of different content graphene oxide (GO) from (1.5 vol% to 6 vol%) have been fabricated at (25
C) temperature. The (GO)/ epoxy composite were studied in terms of electrical properties. The electrical conductivity of the composites is rises from 1.047
1010 (S/m) at pure epoxy to 3.37
1010 (S\m) when the GO content is increased to 6 vol%, scanning electron microscopy (SEM) was shown the interface between the composite composition. The conductivity of composites have been showed the transition from insulation to conduction when took place for graphene oxide to the pure epoxy resin.

Different contents of GO (1.5–6 vol.%) were added to epoxy resin. The GO/epoxy composite was prepared using the casting method and was prepared under room temperature. Mechanical tests’ results such as tensile test, impact test and hardness test show enhancements of the mechanical properties of the GO/epoxy composite. The experimental results clearly show an improvement in the Young’s modulus, tensile strength and hardness. The impact strength was seen to decrease, pointing to brittleness increase of the GO/epoxy composite. A microstructure analysis using Scanning Electron Microscopy (SEM) and X-ray diffraction (XRD) analysis was also performed, which showed how GO impeded the propagation of cracks in the composite. From the SEM images we observed the interface between the GO and …
