According to previous studies, the bond strength between the carbon fiber-reinforced plastics and metals mainly depends on the bond layer between the carbon fiber-reinforced plastic composites and the metal. This article presents the results of the experiments conducted on the tensile bond strength between the carbon fiber-reinforced plastic tubes and aluminum joints. The parameters examined in these experiments include adhesive type, surface roughness of the bonded area, and thickness and length of the bond layer. The results show that the 3M DP-460NS Off-White adhesive was suitable for our experiment. The bonded surfaces of the specimens were smoothened with a P600 sandpaper to achieve higher bond strengths with the adhesive. For the six bond thicknesses tested, a thickness of 0.2 mm was optimal for the tensile experiments. The ultimate tensile force was approximately directly proportional to the bond length.

“…They have not supplied the effects of different curing pressure and adhesive thickness while other factors change. By using the same adhesive, similar thickness and aluminum adherents; failure load of SLJ was reported by Bamberg et al [6] as 8.7 kN and Gültekin et al [8] as 14.7 kN. This difference of 68% needs to be explained by further studies.…”

“…Some researchers report that it could be 13.6 MPa curing conditions at 140 °C for 60 min [4], 23.6 MPa at 60 °C for 120 min [5] and 13.9 MPa 23 °C for 2 days [6]. Along with this, adhesive strength enhancement studies have been proposed by others [7,8] and these pure adhesive strengths were used as a reference of base adhesive strength. These studies focused on strain rate, adhesive thickness or surface quality of adhesive joints but few of them considered all of these together in one work.…”

Development in material science imposes to use different materials in production. This causes a problem for joining different materials because traditional joining techniques such as welding could not overcome this problem in industries such as automotive. Hence, adhesive bonding overcomes this problem by its superiorities to join different materials. The joint strength of epoxy-based adhesives is affected by adhesive thickness, adherent's surface quality, and curing conditions. In this study, two different materials (SAE 304 and AL7075) were bonded by epoxy adhesive (3M DP460NS) as single lap joint (SLJ) of Aluminum-Aluminum, Steel-Steel, and Aluminum-Steel. The effects of adhesive thickness (0.05, 0.13, 0.25 mm) and surface roughness (281, 193, 81 nm) to strength were compared. SLJs were tested for 1, 10, 25 and 50 mm/min displacement rates. Adhesive surface structures were imaged by Scanning Electron Microscopy (SEM) to investigate adhesive fractures. Surface roughnesses were examined by using Atomic Force Microscopy (AFM) to compare its influence on failure load. Finite Element Analysis (FEA) was conducted by using Cohesive Zone Model with ANSYS 18.0 software to obtain stress distribution of adhesive. Optimum values according to the present conditions of the thickness (0.13mm) and roughness (<200nm) were determined. Experimental results were demonstrated that while displacement rates rose, failure loads increased as well. FEA analysis was fit to experimental results. It has been observed that along with material type, peel stresses become an important factor for joint strength.

“…Graphene NPs have also been used as nano-fillers in adhesives. For instance, Gültekin et al [ 144 ] added 1 wt % of graphene to reinforce an epoxy adhesive, which was incorporated to construct double-lap shear specimens with aluminum adherends. Results showed an increase in the failure capacity and ductility of the ABJs.…”

This review paper aims at reporting some of the notable works carried out concerning the use of nanoparticles (NPs) as a means of improving the resistance of fiber-reinforced polymer composite materials (FRPs) and adhesively bonded joints (ABJs) to delamination initiation and propagation. Applications of various nanoparticles, such as carbon-based, ceramic-based and mineral-based are discussed. The main properties that have been considered for improving the delamination and fatigue resistance of FRPs are the interlaminar shear strength, fracture toughness, and fracture energy. On the other hand, cohesive and interfacial strengths have been the focused parameters in the works that considered enhancement of ABJs. The reported results indicate that inclusion of NPs in polymeric matrices leads to improvement of various material properties, even though some discrepancies in the results have been noted. Notwithstanding, additional research is required to address some of the issues that have not yet been tackled, some of which will be identified throughout this review article.
