“…There are numerous literature exploring the effect of stacking sequence of laminated composites and FMLs on impact performances. 31,[71][72][73][74][75][76][77] It is evident that the tendency for interlaminar delamination at the interfaces of plies having differently oriented fibres or different material properties is greater. The interlaminar fracture toughness can be improved by selecting an optimized stacking sequence and interface properties which can effectively improve the impact resistance and damage tolerance.…”

Even though several works are available on the analysis of low-velocity impact (LVI) on fibre metal laminates (FMLs), there is still scope for a better understanding of the complexities associated with their analysis, making it an important area of research. Therefore, it is essential to compile and present the state-of-the-art research in this area to make the critical information available in one paper, facilitating future research. This paper thus covers the detailed review of the articles published on the LVI response of fibre metal laminates (FMLs) based on experimental, numerical and analytical approaches and the associated damage mechanisms under different impact conditions. The discussions can be mainly categorized into two broad groups, namely geometrical and material-based parameters, which significantly influence the structural response of FMLs upon impact. Additionally, the paper compares various numerical techniques reported to model the impact behaviour of FMLs, along with an overview of analytical models. Based on the manufacturing techniques and material constituents of FMLs, the paper discusses feasible methods of improving the performance of impact-prone structures. The exhaustive review of the literature finally concludes that there are scopes of investigating some of the important and relevant areas related to LVI of FMLs like the influence of relative mass of impactor and target and accurate determination of contact stiffness for accurate estimation of interface delamination. Investigating the LVI performance of advanced sandwich structures with FML facesheets is a potential area of research in this direction.

“…Jun Liu [25] studied the impact performance of thermoplastic and thermosetting woven carbon fiber composites under the action of high-speed soft and hard impacting objects using light-air gun experiments. George SE Bikakis [26] investigated the dynamic response of the thin circular clamped GLARE (glass-reinforced) fiber-metal laminates, subjected to low-velocity impacts by a lateral hemispherical impactor that strikes at the center with constant kinetic energy.…”

The glass fiber-reinforced metal laminates (GLARE) cannot be used to form complex laminate structures in the aerospace industry, because there is substantial variation in the plasticity of the heterogeneous materials. Hence, a compound process for composite materials based on the thermoforming technology for aluminum alloy and fiber-reinforced metal laminates (FMLs)-forming technology was proposed; it contains solution heat treatment, thermoforming, quick cold die quenching, artificial aging integrated process (HFQ), and the thermal consolidation of fiber-reinforced metal laminates, and it is named the HFQ-FMLs forming process. In order to test and judge the effect of the heat treatment on the properties of the materials obtained by the new technology, the pure metal sheet and the three kinds of HFQ-FMLs composite laminates fabricated with the different layup method were assessed with the Vickers hardness test and the Charpy impact test at the same time, and they were labeled #1, #2, #3, #4, respectively. In the Charpy impact test, in order to obtain accurate data, the shape and fixing position of the specimen was optimized so that the gap direction was parallel to the loading direction. After the heat treatment, the properties of the aluminum alloy were improved, the hardness will affect the energy absorption of the laminates, and the relationship between the thickness, hardness and impact properties will be analyzed. The hardness test results are 39.9 HV, 37.5 HV, 37.4 HV, 37.1 HV which indicates the pure metal sheet had the greatest hardness, and the greater the thickness of fiber layer, the lower was the hardness of the HFQ-FMLs composite laminate. The impact resistance of the HFQ-FMLs composite laminates was about two times of the pure metal sheet for the same thickness, and the values are 2.3 J, 4.8 J, 4.8 J, 4.8 J, respectively. In addition, the method of laying the fiber layer had no effect on the impact resistance of the composite laminates. For the novel composite laminates subjected to different cutting processes, the scanning electron microscope (SEM) results for the incision morphology suggest that the water cutting process ensures the structural integrity of the composite laminates after the edges’ and holes’ cutting procedures, and the performance maintains continuity.
