“…Lightweight structures are increasingly demanded in a wide range of engineering applications, such as the transportation industry [1][2][3], wind power towers [4] and bridge construction [5]. Especially in the transportation industry, where energy efficiency is required, the use of advanced polymers and their respective composites, such as carbon-fiber-reinforced plastics (CFRP), is rapidly growing due to their inherent capacity to reduce the weight of an engineering structure, such as an aircraft or car.…”

“…The development and employment of different materials with a diverse range of properties helps designers to select the right combination of materials to fulfill the required properties for the desired structure [6]. Despite the benefits of using different materials in a structure, joining of such dissimilar materials such as metal alloys and composites is a great challenge [2].…”

a b s t r a c tThe effects of friction spot joining process parameters on the bonding area and mechanical performance of single lap joints were investigated using full-factorial design of experiments and analysis of variance. On one hand, the main process parameters with significant influence on the bonding area were joining pressure, tool rotational speed and joining time. On the other hand, tool rotational speed and joining pressure displayed the highest influence on the lap shear strength of the joints followed by tool plunge depth, whereas the joining time was not statistically significant. The interaction between the rotational speed and joining time was the only interaction with a significant effect on the mechanical performance. Joints with ultimate lap shear forces varying between 1698 ± 92 N and 2310 ± 155 N were obtained. It was observed that generally a larger bonding area as a result of higher heat input leads to an increased mechanical performance of the joints. The generated regression model by the analysis of variance was used to identify an optimized set of parameters for increasing the lap shear strength of the joints to 2280 ± 88 N. Furthermore, the process temperature was monitored, which varied in the range of 370-474°C.

“…Gas metal arc (GMA) process is the most popular metal joining method using arc with a shielding gas due to its various advantages such as good weld penetration, reasonable brazing speed, less slag, etc., [11][12][13]. However, GMA brazing requires the optimization of various operating parameters, such as arc speed, arc current, filler feeding rate, shielding gas rate, etc.…”

Arc brazing of zinc-coated steel (EG, Electro-galvanized steel) using Cu-3 wt%Si filler metal was performed. The influence of arc current and brazing speed on the bonding properties of the joint, such as bead characteristics, arc penetration, joint hardness, and tensile shear strength were evaluated. The microstructural characteristics of the joint were examined by scanning electron microscopy (SEM) and the compositional information was revealed by energy dispersive spectroscopy (EDS). The throat thickness varies inversely with the brazing speed. The EG joint shows the formation of Fe2Si phases, which result in higher microhardness than the base metal. The tensile samples were fractured in base metal, while minor bead cracks developed in the samples brazed at 80 cm/min-80 A, 60 cm/min-70 A, 70 cm/min-70 A.

Surface & Interface Analysis

The effect of different ratios of carbon fiber (CF) reinforcing polyimide (PI) and surface treatment of CF on the microstructure and wear resistance of surface layers was studied. The increase of CF content led to a gradual increase in the Interlaminar shear strength (ILSS) values, and the maximum ILSS value arises when the CF content is 15 vol%, with an improvement of 13.45% compared to virgin CF composites. The increased interfacial adhesion could be contributed mainly to the presence of branched PI at the interface region. SEM of the worn surface confirms that the plasma treatment efficiently improves the interfacial adhesion of CF/PI composite.
