Today, polymers and composites are widely used as structural materials in various machine elements and engineering systems due to their superior specific properties. However, their use is restricted due to reasons related to surface properties such as tribological behavior and low wear resistance. Recent research has shown that the wear properties of composite materials can be improved by the addition of nanoparticles to composite materials and their homogeneous dispersion in the matrix [1]. Graphene, which is very effective in reducing friction and protecting the surfaces from wear, is one of the most important of these nano additives with its solid lubricating property, low friction coefficient and hard structure [2,3]. In the literature survey made on graphene added nanocomposites, changes in graphene addition ratios can be observed. These ratios generally range from 0.08% to 4% by weight. There are no rules in determining the proportions, and especially in epoxy studies, 0.05-1 ratio is preferred because the homogeneous distribution of the graphene in epoxy becomes difficult as the addition rates increase [4]. Since there is not always a direct correlation between the mechanical properties of the material and its wear properties, the additive proportions that improve the mechanical properties can deteriorate the wear properties or not improve at the same level. In this study, the aim is to determine the most appropriate graphene additive ratio which will be applied to graphene/epoxy nanocomposites and improve wear resistance and to transfer these ratios to fiber reinforced composites in future works.
