“…Furthermore, the adhesive quantity changes the interface state as well as the failure behaviors of FMLs. The importance of adhesive layers in FMLs is mentioned in many researches [14][15][16], however, the related mechanism was few discussed or reported in details. Wilson GS [17] investigated the effect of adhesive layer thickness on fatigue crack growth (FCG) of generalized fiber metal laminates and hybrid materials.…”

“…Hence, the main focus of this research is on the analysis of thermal strains and stresses in FMLs, which are caused by the local embedded heating. This paper supplements the previous conducted researches on FMLs and GLARE, which addressed the temperature dependent material characteristics, residual stresses, the temperature distribution, the long‐term behaviour, and thermal fatigue effects of GLARE and FMLs . This research includes the experimental measuring of the surface strains caused by the embedded heating and numerical modelling of the stress–strain state and temperature distributions.…”

Current trends in aircraft design are to increase the economic efficiency by integrating different features in multifunctional materials. One strategy is to embed resistance heater elements between glass‐fibre epoxy layers in (heated) fibre metal laminates and to use them as anti or de‐icing devices in leading edges of wings. Heated glass fibre reinforced aluminium (GLARE) is an example of such a multifunctional material where heating functionality was added to the (certified) structural feature of GLARE. As heated fibre metal laminates are an innovative and rather new material, the possible (local) effects of embedded heating on the stress–strain state have not yet been investigated. This research couples experimental characterisation of heated GLARE surface behaviour and numerical modelling analysis to investigate the surface and the through‐the‐thickness strain‐stress state and temperature distributions due to the embedded heating. For the experimental part, the surface strains and the temperatures of a developed specimen were measured in a slow heating regime (temperature increase from 22.7 to 39.4 °C within 120 s) using, respectively, a developed shearography instrument and thermocouples with an infrared camera. Then a numerical model of heated GLARE was developed and verified with experimental results. Further, the numerical model was used to predict strains, stresses, and temperatures during a temperature increase similar to that used for de‐icing in a real operation (temperature increase from −25 to 86.7 °C within 4.8 s).

“…Temperature variations build stress at the interface which causes change in fiber orientation and debonding [1]. This phenomenon causes a severe problem of bond breakage between the constituents, by creating cracks or making the existing smaller cracks bigger still, and the failure of composite occurs [3,7,10].…”

The objective of this research work was to estimate the effect of thermal cycling on the tensile behavior of CARALL composites. Fiber metal laminates (FMLs), based on 2D woven carbon fabric and 2024-T3 Alclad aluminum alloy sheet were manufactured by pressure molding technique followed by hand layup method. Before fabrication, aluminum sheets were anodized with phosphoric acid to produce a micro porous alumina layer on surface. This microporous layer is beneficial to produce a strong bond between the metal and fiber surfaces in FMLs. The effect of thermal cycling (-65 to +70ºC) on the tensile behavior of Cf/Al based FML was studied. Tensile strength was increased after 10 thermal cycles, but it was decreased slightly to some extent after 30 and 50 thermal cycles. Tensile modulus also show similar behavior as that of tensile strength.
