Abstract In this study, the effects of different ratios of graphene nanoparticle (GNP) and nanofibers on bonding connections were investigated. For that, with of adhesives DP410 and DP490 of AA5754 alloy samples were bonded with double patches using different ratios of graphene nanoparticle (GNP) and Nanofibers as interlayers. 0.1%, 0.2% and 0.3% ratios of graphene nanoparticle (GNP) were added to DP410 and DP490 adhesives. Samples that were the sizes of 75×30×3 mm of the AA5754 alloy plate and 40 × 30 mm patches cut from the same material were used for double overlapping bonding. After the bonding processes were completed, all samples bonded were subjected to tensile tests to determine the effects of GNP and Nanofibers on bonding connections. And then, the adhesion mechanisms of each sample were determined by taking fracture surface images. In the results of the tensile tests, there were increases in tensile tests of bonding connections using GNP and Nanofibers as using interlayers. The highest tensile force was obtained as 19,258.59 N from the bonding connection where Nanofiber was used together with DP410 adhesive and 0.2% GNP. In addition, in micro and macro structures image examinations, it was observed that higher tensile forces occurred on the surfaces where CHZ + Fiber and AHZ adhesive structures occurred.
