“…This causes stress concentrations and local delamination, and leads to an overall degradation of the mechanical performance of the composite structure. In contrast, joining composites using adhesive bonding provides some important advantages, such as a lower process cost, high strength-to-weight ratio, low stress concentration, and a higher fatigue resistance [ 11 , 12 ]. Adhesive joints also distribute the load over a larger area compared to traditional joining methods [ 13 ], and therefore usually result in higher bonding strength.…”

The use of carbon fibre reinforced polymer (CFRP) materials is increasing in many different industries, such as those operating in the aviation, marine, and automotive sectors. In these applications, composite parts are often joined with other composite or metallic parts, where adhesive bonding plays a key role. Unlike conventional joining methods, adhesive bonding does not add weight or require the drilling of holes, both of which are major sources of stress concentration. The performance of a composite joint is dependent on multiple factors and can be improved by modifying the adhesive layer or the composite layup of the adherend. Moreover, joint geometry, surface preparation, and the manufacturing methods used for production are also important factors. The present work reviews recent developments on the design and manufacture of adhesively bonded joints with composite substrates, with particular interest in adherend modification techniques. The effects of stacking sequence, use of thin-plies, composite metal laminates and its specific surface preparations, and the use of toughened surface layers in the composite adherends are described for adhesively bonded CFRP structures.

“…Moreover, the RSM has been applied to optimize the heat-treated wood dowel joints, processing parameters of medium-density of fiberboards, wood drying conditions, and energy consumption during the mechanical processing of wood [17][18][19][20]. Moreover, more details about the RSM could be found in the literature [21,22].…”

Drilling is one of the oldest and most important methods of processing wood and wood-based materials. Knowing the optimum value of factors that affect the drilling process could lead both to high-quality furniture and low-energy consumption during the manufacturing process. In this work, the artificial neural network modeling technique and response surface methodology were employed to reveal the optimum value of selected factors, namely, drill tip angle, tooth bite, and drill type of the delamination factor at the inlet and outlet, thrust force, and drilling torque. The data set that was used in this work to develop and validate the ANN models was collected from the literature. The results showed that the developed ANN models could reasonably predict the analyzed responses. By using these models and the response surface methodology, the optimum values of analyzed factors were revealed. Moreover, the influences of selected factors on the drilling process of wood particleboards were analyzed.

“…A number of works have shown that this problem is usually overcome by using adhesively bonded joints. In comparison with other techniques, adhesively joints have the advantage of lighter structures, having fewer points of stress concentration as well as, superior fatigue and environmental resistance [4]- [7]. Adhesive for bonding structures is growing more and more, because they present a smooth exterior and ease joining thin or dissimilar materials [8].…”

The present study concerns with the finite element investigation of balanced aluminium single lap joints subjected to tensile loading. Epoxy adhesives were used for bonding having different nanoparticles rate in the epoxy resin (0.5, 1.0, 1.5 and to 2 wt. %, respectively). Two-dimensional (2D) finite element analysis has been employed to determine the peeling stress, von Mises stress, and the shear strain distribution across the midplane of the joints. The results mainly prove that the nanoparticles rate in the adhesive material directly affects the joint tensile strength. Nanocomposite adhesives present a higher failure load than that of neat adhesives. Furthermore, nanocomposite adhesive with 0.5 wt. % of nanoparticles generated strengths (shear and peeling strengths) more than neat adhesives, after which decreased by further addition of the nanoparticles.
