Özet

In this study, fiber metal laminated (FML) composites were produced according to the order of 3/2 stacking by using 0.8 mm thickness 2024 T3 quality aluminum sheets, unidirectional carbon fiber fabric and epoxy resin. In the first production epoxy resin was used without additive. In the second production, graphene nano powder was added to the epoxy resin at a rate of 1%. As a result of the experiments, it was found that addition of graphene nano powder to the epoxy resin provided an increase of 9% in tensile strength and an increase of 24% in the interlaminar shear strength. The amount of permanent compressive stress in the composite increased by about 50%.
