“…9,26,27) The hydrogen bonding between the metal oxide (or hydroxide) layer on a metal surface and (1) a polar group, such as the hydroxyl (-OH) or carboxyl (-COOH) group, in corona-dischargetreated PE, and (2) the amide group (CONH) in PA6, has often been attributed with providing an effective joining force for direct joining of these materials. 9,[21][22][23][24]26) The polar group in plastic materials consists of some atoms that have different electronegativities. For example, the electronegativities of O and H in the hydroxyl (-OH) group are 3.5 and 2.1, respectively.…”

“…In recent years, researchers have investigated techniques for fusion bonding of dissimilar materials using various heat sources, such as laser joining, [7][8][9] ultrasonic welding, 10) induction heating, 11) friction spot joining, 12,13) friction stir welding, 14,15) and friction lap joining (FLJ). [16][17][18][19][20][21][22][23][24] FLJ, which is a novel direct joining method, is derived from a FSW process. The tool used in FSW consists of a stirring probe, to facilitate material flow, and a shoulder part; however, the tool used in FLJ does not require such a probe.…”

Dissimilar material joining of polyamide 6 and polyethylene plates to a plain carbon steel (SPCC) plate was performed using friction lap joining. The polyamide 6 and SPCC plates could be directly joined by friction lap joining, whereas the polyethylene and SPCC plates could not. Corona discharge treatment of the polyethylene surface enabled the joint formation with SPCC. The tensile shear fracture load of the SPCC/polyamide 6 and SPCC/corona-discharge-treated polyethylene joints increased with the joining speed up to 600 mm min − 1 , beyond which it decreased. These joints were fractured at the base material of the plastic plate at optimal joining speeds in the tensile shear test. Continuously joined interfaces of these materials were observed via cross-sectional microstructure analysis. Transmission electron microscopy and selected area diffraction patterns indicated that these materials were joined through the surface oxide layer of SPCC composed of Fe 3 O 4 . The relation between the tensile shear fracture loads and the results of XPS analysis indicated that polar groups such as amide, hydroxyl, and carboxyl groups on the plastic surfaces were highly effective for joint formation of the SPCC/plastic joints.

“…The reason the fracture load of the SUS304/CFRP(PA6) joints increased after the treatment with the silane coupling agent would be that a chemical bond was formed at the joint interface. It has been proposed that the mechanisms of fusion bonding of metal/CFRTP joints are an anchor effect, the Van der Waals forces and the formation of hydrogen bonds between the oxide layer on metal surface and the polar functional groups in the resin of the CFRP [3,[11][12][13]. SUS304 plates with flat surfaces were used in this study to limit the anchor effect.…”

“…In addition, the method results in short joining times, causes limited deterioration of the CFRTP, has a high production rate and low equipment and running costs, can be performed using existing welding power supplies, and is easy to robotise and automate. Because this type of metal/CFRTP joining is based on the interaction between the metal surface and the molten CFRTP, the effects of the type of matrix resin as well as those of any surface treatment of the metal and the welding conditions on the joining strength are likely to be significant [3,[11][12][13].…”

Dissimilar materials joining of SUS304 and carbon-fibre-reinforced plastics consisting of short fibres and thermoplastics was performed. The materials were joined by series resistance spot welding. The electrodes were pressed on the metal plate of the lap joint of metal/carbon-fibrereinforced plastics. The SUS304 plate was heated by resistance heating, causing the thermoplastic near the interface to melt slightly because of heat conduction. SUS304 could be joined directly to carbon-fibre-reinforced polyamide and modified polypropylene, but not to polyphenylene sulphide. The joining area increased with an increase in the welding current and welding time, so did the tensile shear fracture load. Furthermore, the silane coupling agent treatment of SUS304 was highly effective in increasing the joining strength.

“…Thus, achieving a better understanding of the welding process using frictional heat is important for the continued development of the CFRP welding technology. In practical applications, improvement of joint strength is required, and CFRP surface treatment technology [40][41][42] has recently been investigated for this purpose. The objective of this study is to experimentally and statistically clarify the fatigue properties and fracture mechanism of FSSW joints between aluminium alloys and CFRP.…”

The purpose of this paper is to establish the welding technology for dissimilar materials of carbon fibre-reinforced plastic. Therefore, this study focused on friction stir spot welding, which can be simply substituted for spot welding which is widely used for welding of automobile body. In this study, friction stir spot welding was used to weld joints of carbon fibre-reinforced plastic and aluminium alloy, and the effect of aluminium alloy surface treatments on the fatigue properties and the fracture mechanism of dissimilar material joints were investigated experimentally and statistically. As a result, it is possible to create welding joints with high fatigue durability by using the surface treatments on the aluminium alloy.
