Fibre metal laminates, hybrid composite materials built up from interlaced layers of thin metals and fibre reinforced adhesives, are future-proof materials used in the production of passenger aircraft, yachts, sailplanes, racing cars, and sports equipment. The most commercially available fibre–metal laminates are carbon reinforced aluminium laminates, aramid reinforced aluminium laminates, and glass reinforced aluminium laminates. This review emphasises the developing technologies for forming hybrid metal–polymer composites (HMPC). New advances and future possibilities in the forming technology for this group of materials is discussed. A brief classification of the currently available types of FMLs and details of their methods of fabrication are also presented. Particular emphasis was placed on the methods of shaping FMLs using plastic working techniques, i.e., incremental sheet forming, shot peening forming, press brake bending, electro-magnetic forming, hydroforming, and stamping. Current progress and the future directions of research on HMPCs are summarised and presented.

“…The authors added that the specimens with graphene oxide showed a well tensile behavior when compared to the FML samples without the oxidation; also, the tensile strength plus young modulus of the oxidized specimens were raised by 11.7% and 13.5% correspondingly [90]. Li et al [91] studied the mechanical performance of FMLs by examining the influence of shot peen, and the authors focused on studying the static intensity, interlaminar, and fatigue characteristics concerning the FML's shot peened samples. The authors concluded that the tensile intensity of the laminate samples was boosted due to the work hardening within the metal sheets which was caused by the shot peening.…”

The reduction of weight elements is considered as a major objective of several manufacturing companies. This objective will help in growing application sections of the used fiber composites for important structural elements. Modern fiber metal laminate (FML) having lightweight properties is established to be used instead of other substances in different applications including those related to the aerospace industrial sector. Fiber metal laminate is being deemed as an alternative significant substance that is being extensively explored due to its operation, unlike other current materials. There are different profitable FML such as GLARE (glass-reinforced aluminum laminate), established on elevated intensity ARALL glass fibers (aramid-reinforced aluminum laminate), built on fibers of aramid, in addition to CARALL (carbon-reinforced aluminum laminate), centered on fibers of carbon. This paper analyzes important information that contributes to the mechanical characteristics of FMLs under tensile, flexure, impact, etc. conditions.

In this study, a highly efficient method for preparing Al/CFRTP/Al composite laminates by roller preparation was proposed. Three different surface treatments, namely, anodic oxidation, laser texture and surface modification, were used to improve the strength of the metal‐fiber interface. Results show that composite laminates can be prepared efficiently by using reasonable roll pressing technology. The composite laminates with a thickness of 3 mm has good shear strength when the reduction amount is 0.02 mm. Laser texturing increases the contact area at the laminate interface. The surface roughness of Al alloy sheet is improved after laser texture. Moreover, the matrix in the fiber layer of the laminate can be embedded in the gullies formed by the laser texture to form a mechanical interlocking structure. The shear strength of the laminates was further increased when the laser scanning spacing was 2 mm. The highest shear strength of the laminate is 52.4 MPa after using a coupling agent to modify the surface of the Al alloy sheet. X‐ray photoelectron spectroscopy analysis showed that a new chemical bond was generated at the interface between CFRTP and the Al alloy sheet modified with silane coupling agent, thereby forming a molecular bridge among different materials. Mechanical interlocking structure and the generation of new chemical bonds cause the interface to need to absorb more energy during the failure process, which is conducive to the improvement of the interface strength.Highlights Propose roller pressing to prepare Al/CFRTP/Al composite laminates. Effect of laser texture of the laminates interface is clarified. Mechanism of coupling agents at the interface has been elucidated. Efficient preparation of thermoplastic fiber metal laminates has been achieved.
