PREPARATION AND CHARACTERIZATION OF CARBON FIBER EPOXY COMPOSITE COATED BY GRAPHENE
Developing a conductive composite using graphene is very important in manufacturing aircraft structures toward enhancing their electrical properties for future aviation applications. Consequently, this study used reduced graphene oxide (rGO) and functionalized graphene nanoplates (FGNP) to coat carbon fiber-reinforced epoxy composite (CFRE) for improving its properties to obtain an outstanding conductive composite. The painting method was used in this study to coat CFRE with rGO, while the inkjet printing method was used to coat CFRE with FGNP; after that, the conductive composites (CFRE/rGO and CFRE/FGNP) was fabricated using a hot press mold. Morphological characterization using atomic force microscopy was carried out to understand the behavior of the different multiscale laminates manufactured. The results showed that rGO and FGNP coating layers were uniformly and homogeneously distributed over the surface of CFRE, and there were no flaws or creation of voids between the coating layers and CFRE surface. In addition to that, the electrical conductivity of CFRE coated with rGO and FGNP was enhanced and increased significantly with a percentage of 8015%.
