“…The effect of dwell time is studied in this article and a thorough investigation is done to check the quality of the joint. It is found that at some optimum range of dwell time, better joint strength is achieved by larger bond width and finer microstructure [9]. Salonitis et al (2010) have investigated the leaser welding of metal-polymer sandwich sheets in butt configuration by using finite element modelling.…”

The metal-polymer hybrid system is widely used in automobile and aviation sector due to its lightweight characteristics. Besides, it has many advantages such as noise reduction and damping. Inclusion of these system improve the fuel economy, which eventually results in dramatic reduction of carbon footprint. One of the important metal-polymer hybrid system is sandwich panels. These are used as structural members by the transportation industries. Joining of polymers to metals is always a challenge because of their large property difference. Traditional joining methods are not recommended practice in sandwich sheet joining. Till now, many attempts are made to join polymers to metals. This paper highlights various difficulties and defects in joining of polymer to metals. Moreover, effect of process variables is also discussed in detail. The main objective of this review is to find out an efficient process for joining of metal-polymer composite and to establish a systematic approach of improving the quality of joints in sandwich sheets. Key Words: Metal-polymer hybrids, Sandwich sheets, Joining, Welding.

“…In adhesives, the joint strength depends highly on the surface energy of the base materials [10]. Therefore, other joining methods have been explored by researchers to make reliable metal-polymer joints such as laser joining [11][12][13][14], additive joining [15,16] and Friction Stir Joining (FSJ) [17][18][19]. FSJ, based on the friction stir welding concept, is claimed to include the advantages of both mechanical and chemical joining mechanisms for the metal-polymer joints.…”

In this research, friction stir joining of aluminum-polypropylene/talc composite was investigated due to the numerous applications of aluminum-polymer joints in automotive and aerospace industry. A novel tool design, including a rotary/stationary holder was used to improve the appearance and mechanical performance of friction stir lap joints by preventing the mixed molten polymer and aluminum particles from exiting the stirred zone. Effect of tool transverse speed on the joint microstructure and strength was investigated. Using the rotary/stationary holder, tensile-shear strength of the joints increased (by ~45% to ~220% at various transverse speeds). Since during the tensile-shear test, all joints failed from the aluminum/stirred zone interface, joint strength was affected by the formation of anchor-like aluminum pieces in the composite substrate as the mechanical locks, reaction layer at the joint interface and large voids near the aluminum/stirred zone interface. Joining at the optimum transverse speed led to the highest tensile-shear peak load of 315 N.

“…It was because of increase in ductility of weld joint with increase in tool rotation speed, thereby increasing tensile-shear load. Rana et al [7] attempted FSSW on a multi-layered aluminum polyethylene workpiece and observed increase and subsequently decrease in weld strength with increase in dwell time.…”

In this study, friction stir spot welded joints of Al6061-T6 were obtained using Silicon Carbide particles as reinforcement. The effect of reinforced particles along with process parameters was analyzed in terms of tensile-shear strength, weld structure, hook formation. The investigations revealed that tensile-shear strength increased by 29.78 % with incorporation of silicon carbides particles in the weld region. The guiding hole diameter was found to be signi cant parameter for improved weld strength. Combination of moderate tool rotation speed, higher pre-dwelling time and guiding hole diameter were recognized as effective combination of process parameters. Weld cross sections were studied under stereo zoom microscope and optical microscope to observe different bonding regions. The scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) con rmed the presence of silicon carbides particles in weld region.
