“…Recent investigations [29,96] showed that considerable bonding strength is achievable when a polymer is welded to a metal with a relatively smooth surface. To reveal the underpinning bonding mechanism, Liu et al [29] adopted X-ray photoelectron spectroscopy (XPS) to determine the binding states of the elements at the metal-polymer interface.…”

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.

“…Macro-level and atomically locked interfaces (with no chemical bond) are established in the friction stir welded Al/polypropylene joint [10]. Liu et al [11] investigated the interfacial zone of the friction lap welded Al/polyamide 66 joints. It was reported that the formation of Al-O-C bonds at the weld interface improved the resultant joint strength.…”

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.

“…Thus, the polymer-metal hybrid technology has been gradually developed in the automobile parts. The PMH processing technologies mainly contain compression molding [4][5][6], injection molding [7,8], and mechanical welding forming [9,10]. Among these technologies, compression molding is an advantageous processing method due to simple and easy control and operation.…”

“…Jiao et al [9] simulated the PPS-stainless steel laser joining temperature distribution through the finite-element method in the current work, and carried out the laser-based joining experiments, and the results displayed the shear strength reached 17.5 MPa. Liu et al [10] reported aluminum alloy/polyamide 66 was joined via a friction lap welding and discovered the formation of chemical bonds, which was a key factor for the metal/polymer composites to obtain good bonding strength.…”

The polypropylene/aluminum alloy hybrid was prepared via an ultrasonic-assisted hot-pressing technology (UAHPT). The mechanical property and structure of the UAHPT processed polypropylene/aluminum alloy hybrid were explored by the tensile shear test, scanning electron microscopy (SEM), and atomic force microscopy (AFM), respectively. Prior to obtaining the UAHPT processed hybrid, the microporous structures were prepared by the anodic oxidation in a phosphoric acid solution in which the polypropylene (PP) melt flowed into and formed the micro mechanical interlocking structure at the interface of polypropylene/aluminum alloy. The effects of bonding temperature, pressing pressure, ultrasonic amplitude, and ultrasonic time on the bonding properties of the hybrids were investigated via orthogonal experiment. The UAHPT processed hybrid was strengthened and the maximal tensile shear strength reached up to 22.43 MPa for the polypropylene/aluminum alloy hybrid prepared at the optimum vibration processing parameters.
