“…Friction self-riveting is another thermomechanical interlocking process that exploits the micro or macro holes on a metal sheet [6]. This process represents a variant of friction lap welding which needs pre-drilled holes [30,[89][90][91].…”

Multi-materials of metal-polymer and metal-composite hybrid structures (MMHSs) are highly demanded in several fields including land, air and sea transportation, infrastructure construction, and healthcare. The adoption of MMHSs in transportation industries represents a pivotal opportunity to reduce the product’s weight without compromising structural performance. This enables a dramatic reduction in fuel consumption for vehicles driven by internal combustion engines as well as an increase in fuel efficiency for electric vehicles. The main challenge for manufacturing MMHSs lies in the lack of robust joining solutions. Conventional joining processes, e.g., mechanical fastening and adhesive bonding involve several issues. Several emerging technologies have been developed for MMHSs’ manufacturing. Different from recently published review articles where the focus is only on specific categories of joining processes, this review is aimed at providing a broader and systematic view of the emerging opportunities for hybrid thin-walled structure manufacturing. The present review paper discusses the main limitations of conventional joining processes and describes the joining mechanisms, the main differences, advantages, and limitations of new joining processes. Three reference clusters were identified: fast mechanical joining processes, thermomechanical interlocking processes, and thermomechanical joining processes. This new classification is aimed at providing a compass to better orient within the broad horizon of new joining processes for MMHSs with an outlook for future trends.

“…The performance of the adhesive joint drops sharply in the humid and hot environment, while the curing time of the adhesive is long [ 17 , 18 ]. To conquer these shortcomings, new methods of ultrasonic welding [ 19 ], resistance heating welding [ 20 ], friction stir welding [ 21 ], and laser welding [ 22 ] have developed and studied.…”

In the present research, the carbon fiber reinforced thermoplastic (CFRTP) was laser joined with the Al alloy whose joining interface was pretreated by laser micro-texturing, anodizing, and hybrid of laser micro-texturing and anodizing. The surface morphology of the pretreated Al joining interface and bonding strength of the corresponding Al/CFRTP butt joint were investigated. The results show that the laser micro-texturing has fabricated the micro-pit or micro-furrow in the Al joining interface. With the increasing of laser scanning times, the size of the micro-pit or micro-furrow decreases, when the laser scanning distance is constant. The bonding strength of the Al/CFRTP butt joint with Al joining interface pretreated by micro-texturing fluctuates with the increasing of laser scanning distance and times, reaching the maximum value of 20 MPa at laser scanning distance of 0.1 mm and 1 time. The anodizing pretreatment has formed the Al2O3 oxide layer on the Al joining interface. The Al/CFRTP butt joint with Al joining interface pretreated by anodizing obtains the maximum bonding strength of 11 MPa at anodizing time of 10 min. The hybrid pretreatment of micro-texturing and subsequent anodizing fabricates the regular grid structure with smooth micro-furrow and micro-pit, while the hybrid pretreatment of anodizing and subsequent micro-texturing fabricates the Al joining interface with explosive micro-pit and micro-furrow. The bonding strength of the Al/CFRTP butt joint with hybrid-pretreated Al joining interface is relative better than that of the Al/CFRTP butt joint with anodizing-pretreated Al joining interface but almost lower than that of the Al/CFRTP butt joint with micro-texturing pretreated Al joining interface. Such results should be attributed to the surface morphology of the Al joining interface.

“…Bending strength of 56 MPa (20% improvement), a tensile strength of 60 MPa (14% improvement), and hardness of 79 ShoreD (11% improvement) were obtained with the new fed friction stir processed AA6062/ABS joint. Meng et al [20] investigated the friction self-riveting of AA2060-T8/polymer matrix composite joints. The combined effect of adhesion and multi-scale mechanical interlocks was reported to produce a maximum tensile strength of about 27 MPa.…”

Macro-/micro-mechanical interlocking enhancement of hybrid aluminum/acrylonitrile butadiene styrene (Al/ABS) joint is investigated via the use of joint modification approaches such as pre-fabricated threaded-and unthreaded-hole friction stir spot welding processes. The structure, tensileshear failure load, and fracture behavior of the as-welded hybrid Al/ABS joints were investigated. Hybrid Al/ABS joint fabricated with threaded hole shows superior tensile-shear failure load due to the combined effects of compressive shearing-induced and threading-induced mechanical interlocks, and adhesion bonding mechanisms. The tensile-shear failure load of the threaded joint improved from 654 to 749 N as the tool rotational speed is increased from 710 to 1120 rpm. A rise in tool rotational speed improves the failure resistance of the hybrid Al/ABS joints (threaded and unthreaded) owing to the enhanced mechanical interlocking, bigger Al anchor/chip, and smaller interfacial gap between the re-solidified ABS and Al anchor. Threading and tool rotational speed have significant impacts on the fracture location and mode of the hybrid Al/ABS joint. The pre-fabricated threaded-hole friction stir spot welding process is thus recommended for the enhanced micro/macro-interlocking in hybrid Al/polymer joints.
