“…In the 1980s, aramid-fiberreinforced aluminum alloy laminates (ARALLs) [9,10] were implemented in the aerospace industries due to their impact strength, fatigue resistance and anti-corrosive nature that remained stable. In the late 1990s, glass-reinforced aluminum laminates (GLAREs) [11][12][13] were used in the aerospace industry due to their excellent properties. According to the cited literature study, glass fiber produces good results in mechanical properties [14,15].…”

Nowadays, in the automation and aircraft industries, there is a challenge in minimizing the weight of components of vehicles without losing the original properties. In this study, we fabricate hybrid composites based on fiber metal laminates; these materials could be promising composites for high-performance applications. This work is focused on analyzing the effect of high temperature (175 °C) on the mechanical properties of these kind of materials, by introducing NaOH and silane adhesion treatments between metal and prepreg layers and by using vacuum molding processes. Fabricated FML (NaOH treatment) shows a significant improvement in tensile strength in comparison with the ARALL and GLARE reported by ESA. Moreover, developed FMLs at 175 °C kept more than 70% of their tensile strength and modulus and kept 4% of tensile strain at room temperature. The prominent conclusion achieved in this work has been that excellent candidates have been obtained for a wide range of applications, including but not limited to space and aerospace applications.

“…According to the classification of metal (e.g., aluminum, magnesium, and titanium) and fiber (e.g., aramid, glass, and carbon), FMLs can be divided into four categories, respectively ARALL (Aramid-Reinforced Aluminum Laminates), GLARE (Glass-Reinforced Aluminum Laminates), CARALL (Carbon-Reinforced Aluminum Laminates) and TiGR (Titanium/Graphite Hybrid Laminates) (Mukesh and Hynes, 2019). Among them, GLARE has become the research focus of many scholars in the last two decades with good features of strength, weight reduction and particularly formability (Annamalai et al, 2021). However, due to the fiber's low plastic deformation ability, forming of complex parts is limited (Sinke, 2003).…”

Recently, hydroforming has paid dividends in composite forming due to its uniform pressure distribution, which helps in reducing the delamination defects. Considering the need to develop an appropriate criterion for evaluating the formability of FMLs, inspired by sheet metal forming and testing, the uniform pressure loading test was adopted to characterize the formability of semi-cured FMLs by forming limit curve ( FLC). In this paper, both theoretical analysis models considering and ignoring the tangential cohesive effect were established, and the stress expression of the critical zone was given. The results show that the tangential cohesive stress demonstrates a non-negligible influence on the FLC. A new form of comprehensive FLC was given by defining global equivalent strain and global strain ratio and analyzed by the finite element method. In addition, the numerical simulation model and the experimental parameters were verified. A simplified Hashin criterion was proposed and developed into the numerical simulation as a subroutine based on theoretical analysis. Parameters such as blank holder pressure, pressure rate, and temperature were considered both in experiments and simulation. Only fiber stretching damage was distinguished in the cross, single, and arc crack but no wrinkling. As predicted theoretically, a lower forming limit is expected when FMLs are subjected to greater tangential cohesive stress. Finally, with the help of numerical simulation, the influence of different boundary conditions on the comprehensive FLC was studied. Instead of a simple evaluation of FMLs, this comprehensive FLC could be used directly to optimize hydroforming processes in the engineering field.

“…Due to the complex failure mechanisms of the FML arising from multiple phase material characteristics, its structural integrity in service remains one of the major challenges to the aviation industry [4] . It has been reported that static and fatigue behaviours and failure mechanisms of the FML are significantly affected by numerous factors, such as metal types and volume fraction [5] , metal surface treatment technology [6] , fibre type [7] , stacking sequence [8] ,…”
