“…They found that the effect of increasing extension rate at a given temperature is generally to increase the failure load while simultaneously decreasing the joint ductility. Sayman et al [7] investigated adhesively bonded single-lap joints under different temperatures and transverse impact energies. They observed that when the temperature increase the strength of joints decreases.…”

In this study, the load-carrying capacity of a single-lap joint bonded by an adhesive was determined experimentally. Glass fiber-epoxy composite material was chosen as adherends and Loctite 1 9466 A&B2 was used as adhesive. The vacuum assisted resin infusion method (VARIM) was used to manufacture composites. In this experimental study, the effects of hole drilling and temperature were investigated. Five hole configurations and three temperatures (room temperature, 50 C, and 80 C) were considered. The results show that hole drilling elevate the failure load and when the temperature increases the load-carrying capacity decreases.

“…It is found with the use of a dynamic FEM that such conditions produce a mixed mode load, but as the crack propagates through the adhesive, mode II becomes the main loading mode. Sayman et al [22] have investigated the load-carrying capacity of a single-lap joint bonded by an adhesive by experimental method. They have used glass fiber-epoxy composites as adherends and Loctite 9466 A&B2 as an adhesive material.…”

This experimental study deals with the flexural behaviors of composite single-lap adhesive joints after impact tests. Increasing impact energies are applied at the center of the composite plates having three different overlap lengths. It is shown that the overlap lengths and impact energy levels affect considerably the impact responses of the composite single-lap joints. It is also shown that the bending stiffness of the composite increases with increasing overlap length. For this reason, after the impact tests, how these effects influence the flexural behaviors of the impacted composite lap joints was also investigated. The flexural loads of the impacted and non-impacted composite single-lap joints were determined and compared with each other. It is shown that the residual flexural loads after impact increase with increasing overlap lengths but decrease with increasing impact energy.

“…1 The use of these joints on laminated composites made of glass fiber reinforced plastic (GFRP) and metallic materials put to use in the aforementioned industries has markedly risen during recent years, using different types of adhesive bonding, 2-4 types of adhesives, 5,6 and the profile of the edges of the joint. [7][8][9] The static and dynamic behaviors of adhesively bonded joints were already studied by several researchers [10][11][12][13][14][15][16][17] using various adhesives and adherents. In general, it was demonstrated that toughened epoxy adhesives are used when the adhesive features in the strength of entire structure.…”

“…They also indicated that the common practice of treating the specimens before bonding was performed by sanding and/or wiping with a primer solution. Sayman et al 15 treated the surfaces of GFRP specimens by wiping them with acetone. An ultrasonic process to clean the adhesion surfaces of composite joints and a chemical bath application to these surfaces were reported by Ferreira et al 13 Besides the experimental results of bonded joints, researchers have also developed various analytical and numerical models in order to determine the response of joints with respect to loading conditions.…”

The joining techniques of lightweight and strong materials in the transport industry (e.g. automotive, aerospace, shipbuilding industries) are very important for the safety of the entire structure. In these industries, when compared with other joining methods, the use of adhesively bonded joints presents unique properties such as greater strength, design flexibility, and reduction in fuel consumption, all thanks to low weight. The aim of this study was the analysis of the tensile fatigue behavior of adhesively bonded glass fiber/epoxy laminated composite single-lap joints with three different specimen types including 30, 40 and 50 mm overlap lengths. In this study, composite adherents were manufactured via vacuum-assisted resin transfer molding and were bonded using Loctite 9461 A&B toughened epoxy adhesive. The effect of a surface treatment method on the bonding strength was considered and it led to an increment of about 40%. A numerical analysis based on a finite element model was performed to predict fatigue life curve, and the predicted results showed good agreement with the experimental investigation.
