Abstarct: Fiber mextal laminates (FMLs) are a new group of composites, made of mextal sheets with thin thickness and reinforced composite laxyers with different fibers. FMLs have high properties of mextals and composites. They can be used with a different type of mextal alloys, fiber and resin types, several laxyers and various orientations of fibers. Some of the best characteristics of fiber mextal laminates can be attributed to high resistance to corrosion and chemical environments, high impact resistance to aluminum, superior fatigue properties to mextals, resistance to high flame retardant high to weight ratio.In this study, the effect of adding nano clays into the epoxy resin of the core of FMLs on buckling and flexural behaviour of FMLs reinforced with natural fibers has been investigated. FMLs were made of 2024 aluminum alloys and 828 epoxy resin with theta hardener and natural kenaf fibers in the form of two-way fabric and modified Montmorillonite clay nano particles with values of 0, 3, 5 and 7%. The results show that the flexural and buckling strength of the FML increase by adding different amounts of clay nano particles to the matrix. baxsed on the results of the experimental tests, the samples containing 5wt % nano particles obtained the highest compressive and flexural strength among other samples. Also, in order to investigate the distribution of clay nano particles in the matrix and its effect on strength and adhesion between the composite core and the aluminum laxyer of the surfaces, morphology was performed on the samples and scanning electron images were compared. Finally, the experimental results were compared with those of Abaqus finite element simulation software.
