Effects of Reduced Graphene Oxide Particles on the Creep Behavior of Adhesively Bonded Joints

In this research, effects of introducing 0.5wt% reduced graphene oxide (RGO) reinforcement on the creep behavior of the adhesivelybonded joints are investigated at 25oC,55oC. To this aim, uni-axial creep tests are conducted,creep deformations of the bulkspecimens produced via the neat adhesive,adhesive-RGO composite are recorded. Also, creep tests are performed to obtaincreep behavior of the single lap joints. Furthermore, results of the bulk specimen tests are used in a finite element based numericalanalysis to simulate the creep behavior of the joints. Results show that, a significant decrease in the creep deformations along with aremarkable increase of 30% in the creep life time occurs in the reinforced joints. Finally, comparing the numerical results andexperimental data shows that the numerical analysis accurately simulates the creep behavior of the joints.
