Abstract

In this study, the effects of different ratios of graphene nanoparticles (GNP) and Nanofibers on bonding joints were investigated. Therefore, AA5754 alloy samples were bonded by adhesive DP460 and using different ratios of graphene nanoparticle (GNP) and Nanofibers. 0.1%, 0.2% and 0.3% were added to GNP, DP460 adhesive. Samples of 75x30x3 mm and patches of 40x30 mm were used, which cut from AA5754 alloy plate. Tensile tests of samples were conducted to see the effects of each parameter on the bonding joints after the bonding process. After tension tests, macrostructure and SEM analyses of the rupture surfaces were performed. In conclusion, the best tensile damage load has been obtained in bonding joints where Nanofiber has been used together with 0.2% GNP. In addition, it has been observed that CHZ + Fiber + CHZ and AHZ + CHZ structures seen in macrostructure images have positive effects on tensile test results.
