“…, k l is the Lamb wavenumber, and k s and k p are the shear and compression wavenumbers, respectively. Having the Poisson's ratio of the specimens, one may calculate the shear wavenumber using the measured Lamb wavenumber through the solution of Equation (6). Then, the shear and elastic moduli of the propagation medium can be respectively estimated via 22 :…”

[3][4][5][6][7][8] Despite many desirable properties the FMLs possess, they undergo different types of damage including matrix cracking, delamination, and fiber breakage when exposed to tension, compression, bending, impact, and fatigue loadings. 9 The matrix cracking is often the first damage that occurs in composite materials and fiber-reinforced composite layers of FMLs.…”

“…FMLs have the advantages of both the fiber‐reinforced composites and metals and exhibit mechanical properties that may be superior to those of the conventional fiber‐reinforced composite laminates or monolithic alloys 2 . Therefore, the application of FMLs has been increased in the form of plate‐like or thin‐walled structures in different engineering sectors, such as aerospace, automotive, and marine 3–8 . Despite many desirable properties the FMLs possess, they undergo different types of damage including matrix cracking, delamination, and fiber breakage when exposed to tension, compression, bending, impact, and fatigue loadings 9 .…”

The purpose of the present study was to assess the capability of finite element (FE) simulations of guided Lamb wave propagation for the characterization of the modulus of fiber-metal laminates (FMLs) and detection of the matrix cracking in them. An FE model of an FML specimen with a [Al/90 2 /Al/ 90 2 /Al] layup was developed. The matrix cracking with different densities was also induced in the fiber-reinforced composite layers of the FML model. The fundamental antisymmetric Lamb wave mode was propagated on the developed model at frequencies from 50 to 300 kHz. The Lamb wave velocity was obtained from the FE models at different frequencies. Then, the inverse Lamb wave propagation problem was solved and the elastic modulus of the simulated FML specimen was estimated. An experimental program was conducted to evaluate the results of FE simulations. The FML specimens with the same layup and materials were fabricated and underwent the tensile and Lamb wave propagation tests. The average elastic moduli of the specimens obtained from the tests, classical lamination theory, and FE simulations were in good agreement, especially at low frequencies. It was observed that the sensitivity of the Lamb wave velocity to matrix cracks was higher at high frequencies.

The primary goal of this study is to see how multi-walled carbon nano tubes (MWCNTs) and nano silicon carbide particles (SiC) affect basalt reinforced epoxy composites made using pressure mould. The aluminium 8090 metal plate was used to strengthen the laminate's core. Tensile, bending, and low velocity impact tests, as well as aesthetics, were investigated and presented for the debate. The physical and low velocity impact characteristics of the produced laminates are considerably improved by including MWCNT/SiC into the epoxy matrix and basalt mixture. The 9 wt. % and 12 wt. % of SiC filled combinations show higher tensile and flexural performances up to 40% than neat composites among the investigated combinations. Drop weight impact tests show a progressive improved energy absorbing response of up to 60% as SiC reinforcement increases. SEM morphology of pure, SiC/MWCNT filled specimens, as well as fragmented surface analyses, were also presented. It was observed from morphological studies that there is a reasonable wettability between matrix/filler/ reinforcements. This research work will lay a path for using Basalt/Epoxy/MWCNT/SiC Reinforced Hybrid Fiber Metal Laminates for aerospace and structural applications.

“…Fibre metal laminates (FMLs) were developed due to the limitations of metals, which relate primarily to their large weight, and the limited use of classic composites. These consist of alternating layers of metal and a polymer composite reinforced with fibres [1][2][3]. The first FMLs were developed in the laboratory in the mid-20th century.…”

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.
