“…HBF joints are joints that simultaneously use adhesive bonding and mechanical fastening, 11 allowing the benefits of both adhesive and mechanical connections to be considered. 12,13 Several studies [14][15][16][17] have shown that the proportion of the external load carried by adhesives and fasteners in hybrid joints is one of the most important factors affecting the load-carrying capacity of joints. During the loading process of sandwich joints, the load distribution between the adhesive and the fastener is dynamic due to the deformation and failure of the adhesive layer.…”

A finite element model of damage accumulation in the joint's tensile process was developed in ABAQUS software to address the complex load transfer mechanism of the hybrid adhesive-riveted joint of the carbon fiber sandwich structure. The change in adhesive-riveted energy was used creatively to characterize the joint's load-sharing law after verifying the accuracy of the simulation results. In addition, the effects of load sharing and eccentricity on the joint's tensile performance were investigated. The results show that the adhesive load came before the rivet load, but increasing the number of rivets improved the proportion of rivet load and prevented the adhesive layer from failing. A greater number of rivets also reduced the fluctuation of eccentricity, which affected the tensile load and crack propagation.

“…A more uniform stress distribution combined with the flexibility to join many different types of materials are key advantages of adhesive bonding 5–9 . The use of adhesives in combination with other fastening techniques has also been explored by authors to improve the strength of the joints 10–12 . Despite its benefits, the use of adhesives has some important drawbacks, being one of the most important high sensitivity to severe environmental conditions.…”

[10][11][12] Despite its benefits, the use of adhesives has some important drawbacks, being one of the most important high sensitivity to severe environmental conditions.

Despite existing studies on the effects of temperature on the behavior of bonded joints, the role of loading mode and test type (strength, fatigue, and fracture tests) on the rate of degradation of adhesive/joint properties at high temperatures has not been adequately investigated. The aim of the current study is to determine if adhesives experience the same rate of degradation at high temperature when they are subjected to different mode mixities. To do so, an epoxy adhesive was subjected to strength, fracture, and S–N fatigue tests, for modes I and II, at different temperatures. The results show that there is a significant difference between the rate of degradation in mode I/tensile and mode II/shear loading conditions. It was also found that the rate of degradation in adhesive properties is a function of test type. Based on the results, by increasing the temperature, a less reduction in tensile strength was found in the Arcan joints (almost 50% reduction) compared with the dogbone specimen (where the strength was reduced by less than 40%). According to the results, for all the considered tests, temperature sensitivity was more noticeable in tensile loading conditions compared with the shear mode. It is shown that despite the reduction in tensile fracture energy with temperature (by around 23%), the shear fracture energy was improved (by over 20%) at 50°C. Based on these results, an S–N model was also developed to create a master S–N curve, plotted as a function of temperature.

“…Some of these techniques are adhesively bonding [9,[13][14][15], welding [16,17], mechanically fastening [18,19] and a combination of different types of techniques called hybrid joints [20]. Among these methods, hybrid joints obtained by combining mechanical fastening (e.g., riveted joints and bolted joints) with conventional adhesive joints have become very popular in recent years [20][21][22][23][24][25][26][27][28]. Fu and Mallick [22] investigated the fatigue life of hybrid joints in the composite.…”

Glass fiber-reinforced composites are commonly employed as structural materials in many fields. In addition, glass fiber-reinforced composites are frequently used with metals, particularly in the automotive and aerospace industry. In this context, the tensile strengths of simple and hybrid single-lap joints having similar (i.e., aluminum/aluminum and composite/composite) and dissimilar (i.e., aluminum/composite) plates were investigated experimentally in this study. At this point, 6061 aluminum alloy and E-glass/epoxy composite plates were used as the adherends and Araldite 2014-1 was used as the adhesive. The composite adherends produced using the vacuum infusion technique consist of E-glass/epoxy laminates with [0°/90°/+45°/−45°]6 stacking sequence. Two different types of joints (i.e., adhesively bonded and bonded/riveted) were employed for similar and dissimilar joints. In addition, both 3-rivet and 4-rivet joints were used in bonded/riveted joints. The results revealed that the strength of the joints could be considerably increased with the addition of rivets to the adhesively bonded joints. In particular, the results showed that the strength value of the bonded/4-riveted joint is 5.7 times higher than the adhesively bonded joints.
