چکیده

Reinforcement of adhesives by adding nano particles is an important issue for enhancing mechanical performance of bonded lap joints. In this paper, functionalized graphene nano platelets (GNPs) and nano silica particles were added to the structural epoxy adhesive at three weight percentages by implementing four dispersion procedures. The effect of dispersion procedures were investigated on static behavior of nano-reinforced adhesive Al-GFRP single lap joints subjected to four-point bending. Experiments revealed that, for a constant wt% of functionalized GNPs, using magnetic stirring and ultrasonic probe resulted in the greatest static failure load. But for nano silica particles, the maximum failure load was obtained by implementing the magnetic stirring and bath sonication procedure. Moreover, increasing the wt% of each nano particle in the adhesive enhanced the static failure load of the corresponding joint
