Multifunctional reduced graphene oxide coating on laminated composites

Carbon Fibre Reinforced Plastics (CFRPs) are commonly used for structural applications due to their high specific mechanical properties. CFRPs can also be functionalized exploiting a combination of several materials that introduce multifunctional features the global performance structure and widen range operations. This work investigates use Reduced Graphene Oxide (RGO) Film as coating on CFRP laminates. Exploiting inherent properties these films, surface composite structures such electrical conductivity wettability improved. Moreover, potential built-in functions, live strain sensing DC-biased thermography, studied. Three point bending tests demonstrated negligible influence RGO films flexural laminates confirmed satisfying adhesion between structure.
