“…The improvement of the adhesive bonding properties in hybrid structure was the interest of some studies [12,13]. Manufacturers invested in higher stiffness, durability as well as light weight segments which are widely used in aircrafts, automotive, and electronic industries [14,15]. Metal and polymer joining is difficult because of differences in mechanical and physical characteristics [16].…”

Abstract. The hot press method is used to join a poly-ethylene plate of thickness 4 mm with an aluminium alloy AA6061-T6 plate of thickness 1.5 mm. A preanodizing process is crucial for the success of such joint. The anodizing was performed under a current density of 200 A/m 2 , temperature 24°C, sulphuric acid 5 wt. % and for a 60 minutes. Three period parameters were considered in the hot pressing process; temperature: 115 and 135°C, pressure: 2, 6, and 10 bar and pressing time: 1, 2, 3, 4 and 5 minutes. The joint specimens are tested by shear tensile test, microstructure, energy dispersive spectrometry, differential scanning calorimetric and thermo grvanometric analysis. The results of shear tensile were analyzed using design of experiments. Minimum and maximum shear tensile force were found at temperature T = 115°C where; F min = 680N and F max = 2800N. From Pareto chart, the applied pressure had the most significant effect on the shear tensile force of the joint specimens compared to temperature and joining time. The main effect plot showed that optimum value of shear tensile force was obtained at joining conditions of T = 135°C, P = 6 bar and t = 3 minutes. The tested specimens exhibited an interfacial shear failure, extension and necking in the region of polymer with a ductile fracture. The mechanical interlocking of polymer element in the anodizing surface is approximately 15 µm. The melting point and glass transmission temperature of PE are decreased after the hot press.

Clinching is a method for mechanically joining sheet metal of different thickness and properties in which the two plates to be joined undergo plastic deformation. The clinching process is established by connection or joining using simple tools: a punch and a die. This method has different characteristics compared to thermal joining methods, such as spot welding, including low purchase and operating costs, little preparatory work, safe and environmentally friendly, interesting mechanical properties, reproducibility, and durability. In this article, a brief review of traditional joining methods for dissimilar materials and the clinching process are illustrated in greater detail. In addition, the article looks to guide researchers for future work by identifying weaknesses of the current processes as well as potential for valuable contributions in the field of clinching.

“…Currently, researches have been conducted on steels and aluminium alloys, recent developments have dealt with copper, mag- nesium, titanium alloys [15,16], carbon fiber-reinforced plastics [17] along with hybrid metal-plastic polymers [18][19][20], metal-reinforced plastics [21][22][23] and metal-wood [24]. Some of these materials were joined by hole-clinching process [25]. The joined materials do not require the surfaces to be specially prepared.…”

Abstract:The optimization of a car body in terms of cost can be achieved by using different materials in various positions of the car in order to utilize specific properties of each different material. Resistance spot welding is the most used method of joining in car body production, but it is not always easy or even possible to join some combination of materials by this method. Clinching is an alternative method to spot welding, as a combination of drawing and forming. The research is focused on the evaluation of clinched joints' properties using shearing test and metallographic observation of material structure.
