Abstarct: In this study, the interlaxyer strength of fiber-mextal laminate composite (FML) that reinforced with graphene nanoparticles under fatigue loading has been investigated experimentally. The mextal used to make the FML specimens is T3-2024 aluminum alloy, the fibers used are woven glass fibers, and the resin used is epoxy resin. According to the studies, graphene oxide nanoparticles were used as reinforcement. Samples of tensile, peeling and fatigue test include samples without nanographene oxide and also with percentages of 0.1, 0.25 and 0.35 nanographene oxide. In all of the above tests, specimens containing nano-graphene oxide showed better fatigue strength. Fatigue strength was higher by 388% for samples containing 0.1% nanographene oxide than for samples without graphene oxide. Also, peeling test results showed that adding the same amount of nanographene oxide to epoxy resin increased the adhesive properties by 122%.
