“…Feng et al 175 obtained similar results when the absolute and specific mechanical properties of pineapple leaf fiber‐reinforced FMLs were compared with those of composites and fabric counterparts; that is, the absolute and specific mechanical properties of the FMLs were higher than those of composites and fabric counterparts. Kandare et al 176 examined the effect of notch sensitivity on the static and dynamic properties of flax‐based FMLs. Their tensile strengths were found to decrease as the diameter‐to‐width ratio of the notch increased.…”

The development of hybrid materials consisting of alternating layers of metal alloys and polymeric composites has revolutionized the engineering field. These metal‐composite laminates combine the merits of each individual component, forming advanced and promising structures which could be employed for structural applications. The low fatigue crack growth rate and high damage tolerance of these materials are particularly fascinating. When developing metal‐composite laminates with superb functional properties, the combination of several metal surface treatment techniques is a common practice to ensure optimum metal‐composite adhesion. Today, a new cutting‐edge manufacturing technique utilizing nano‐porous network film has been established to get rid of the massive infrastructure of conventional autoclave techniques and produce first‐rate materials. Even though various techniques can be adopted to manufacture metal‐composite laminates, the selection of the techniques is highly dependent on the nature of the polymer matrix. After the manufacture of the metal‐composite laminates, post‐stretching is considered a critical step to alleviate the unfavorable residual stress to ensure the optimum performance of these materials for long‐term service. When dealing with natural fibers, it is worth mentioning that the processing temperature should be limited to below 200°C regardless of manufacturing technique to avoid fiber degradation. Metal‐composite laminates consisting of synthetic/natural fibers are considered a viable option to offset the demerits of each kind of fibers. By incorporating fatigue‐resilient natural fibers in the laminates, it is expected that the overall fatigue resistance of the laminates can be apparently enhanced, which is in line with the initial goal of developing metal‐composite laminates.Highlights Fiber bridging offers fiber‐metal laminates with superior fatigue properties. Metal surface treatment is vital to ensure an optimum fiber‐bridging mechanism. A novel out‐of‐autoclave method can produce first‐grade fiber‐metal laminates. Post‐stretching is needed to lessen residual stress in fiber‐metal laminates. Hybrid fiber‐metal laminates are feasible for structural applications.

The ever-growing use of eco-friendly cellulosic fibers in composite materials has triggered the interest in adopting such fibers in fiber-metal laminates. Ramie is one of the cellulosic fibers that show high mechanical strength and stiffness. This work aims to explore the feasibility of encapsulating woven ramie core in fibermetal laminates. The sandwich laminates and composites were fabricated using the hot molding compression method. Tensile, flexural, Charpy impact and quasistatic indentation tests were carried out to identify the mechanical performance of fiber-metal laminates based on woven ramie core. Meanwhile, the mechanical tests were also performed on the composite laminates and woven ramie fabrics for comparison purposes. Based on the findings obtained, ramie fiber-reinforced metal laminates exhibited eminent absolute and specific mechanical properties compared to their associated ramie fabrics and ramie fiber-based composites. The specific tensile strength of metal laminates is 3.80% and 50.56% higher than that of ramie fabrics and composite laminates. It was also found that the specific flexural and impact strengths of metal laminates are 70.02% and 89.12%, respectively, greater than those of composite laminates. In terms of quasi-static indentation, metal laminates displayed specific energy absorption of 35.25 J/g/cm 3 , which is 388.23% greater than composite laminates. These findings corroborated the addition of aluminum skin layers provided the laminated structures with superior absolute and specific mechanical properties. Thus they could be an alternative material to be used in transportation sectors to improve energy efficiency and mechanical performance.

Fiber metal laminates (FMLs) have mainly been used in aerospace applications with synthetic fibers. To improve their environmental credentials and address issues regarding the end‐of‐life of these materials, a shift to FMLs based on natural fibers can be a promising course of action. However, regarding them as conventional FMLs overlook some of the unique benefits of natural fibers. Therefore, this study pioneers the examination of FLAx‐REinforced aluminum (FLARE) for its combined impact resistance and vibration damping. Dynamic mechanical analysis and vibration beam tests demonstrate that the metallic layer predominantly influences the damping behavior of FLARE. The loss factor notably decreases with aluminum addition (by 80% compared to the flax composite), approximated via an inverse mixture rule. Low‐velocity impact tests highlight the role of aluminum layers in energy absorption and the composite strength as a critical factor in impact resistance. FLARE exhibits 25% less specific energy absorption compared to its glass fiber counterpart. A quasi‐static analytical model suggests the potential of FLARE for practical applications. With its balance of properties and considering its potential advantages at end‐of‐life, allowing recycling of aluminum, and its expected lower carbon footprint, FLARE renders potential beyond the aerospace sector, e.g., in other forms of transportation.
