“…Furthermore, the incorporation of a metal constituent can increase the materials poor electrical conductivity potentially enabling additional functionalities such as electrical shielding, grounding, or structural health monitoring [ 4 ]. Carbon fiber reinforced polymer (CFRP), being one of the few electrically conductive FRP, represents the superior FRP considering mechanical performance and has already been combined successfully with metals like steel [ 5 ], aluminum [ 6 , 7 , 8 ], or magnesium [ 9 , 10 ] to form hybrid laminates.…”

Combining carbon fiber reinforced polymers (CFRP) with steel offers the potential of utilizing the desired characteristics of both materials, such as specific strength/stiffness and fatigue strength of fiber reinforced polymers (FRP) and impact resistance of metals. Since in such hybrid laminates multiple material layers are combined, a gradual failure is likely that can lead to changes in mechanical properties. A failure of the metal partner leads to an increase in stress on the FRP, which under fatigue load results in increased self-heating of the FRP. Therefore, a suitable testing procedure is required and developed in this study, to enable a reproducible characterization of the mechanical properties under fatigue load. The resulting testing procedure, containing multiple frequency tests as well as load increase and constant amplitude tests, enabled characterization of the fatigue performance while never exceeding a testing induced change in temperature of 4 K. In addition to the development of the testing procedure, an insight into the manufacturing induced residual stresses occurring in such hybrid laminates, which impacts the load-bearing capacity, was established using finite element simulation. The gathered data and knowledge represents a basis for future in-depth investigations in the area of residual stress influence on the performance of hybrid laminates and highlights its importance, since not only the used testing procedure determines the measured fatigue performance.

“…A larger damage area would also dissipate more impact energy. 8 It should be noted that different damage mechanisms will be produced during the impact process, resulting in various complex behaviors for the FMLs as heterogeneous structures under high strain rate loading conditions, which may mask the influence of nanoparticles on FMLs.…”

“…However, the poor interface performance between fiber and magnesium layer limit its application. [6][7][8] In order to further improve the performance of these materials, different improvement schemes are continuously proposed. At present, the schemes can be divided into two categories: (i) metal surface treatment, such as mechanical treatment (sandblasting and grinding), 9,10 and chemical treatment (anodic oxidation, etching and adding interface layer).…”

In order to investigate the effect of graphene oxide (GO)/multi wall carbon nanotubes (WMCNTs) on the mechanical properties and low‐velocity impact response of magnesium‐based fiber metal laminates (FMLs), the FMLs specimens reinforced with GO, WMCNTs or their mixture were prepared, and quasi‐static tensile and low‐velocity drop hammer impact tests were performed. The tensile test results showed that the mechanical performance of FMLs could be improved by adding a certain concentration of nanoparticles. The tensile strength increased by 14.9% and 26.6% when the concentration of GO or WMCNTs is 0.6 wt%, respectively. Due to the agglomeration phenomenon, there are the opposite effect for the tensile strength of FMLs when the particle concentration is excessive. After the mixture of GO and WMCNTs was added to the epoxy matrix, the tensile strength of FMLs could still be increased by 12.8% at the GO to WMCNTs ratio of 0.6:0.9 (the overall concentration of particle is 1.5 wt%). And the elastic modulus is also significantly increased, but it has a negative effect on the ductility. The low‐velocity impact test results showed that the FMLs reinforced a mixture of GO and WMCNTs have greater peak impact load due to the lager stiffness. The FMLs reinforced with WMCNTs have better energy absorption capacity under impact load due to lager damage area.

“…These properties derive from the properties of the individual components and depend on the properties and orientation of the reinforcing fibres, the kind of metal layer and its thickness [36][37][38]. The orientation of the fibres in relation to the successive layers of the FML determines the anisotropy or isotropy of the resultant composite [39,40]. Fibres used for their production can be continuous or discontinuous (staple fibres, whiskers) [41,42].…”

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.
