Abstract
Cu is most commonly used as a matrix in composites for high electrical and thermal conductivity. Recently, graphene has been researched to improve mechanical and electrical properties as reinforcing materials of composites owing to its excellent physical characteristics. Therefore, the purpose of this study is to evaluate the effects in electrical conductivity according to the shape, structure, and the volume fraction of the graphene reinforcement for Cu/graphene composites. For the evaluation of the variation in electrical conductivity according to the shape and the volume fraction of graphene platelets, RVE was analyzed for models in the location and orientation of graphene which were randomly arranged or not. The change in electrical conductivity of the volume fraction and aspect ratio of graphene platelets was evaluated by using the ABAQUS program. Depending on the angle of graphene platelets, the electrical conductivity was the highest at 0°. In addition, in a relatively high volume fraction model, the electrical conductivity decreased quickly according to increase in the angle, and the variation was changed at angle 45° for the AR.
