    The effect of GNP addition on mechanical and residual stress properties of 2024-T3 aluminum and carbon fiber reinforced FML
    (Iop Publishing Ltd, 2019) Askin, Mustafa Yunus; Turen, Yunus
    In this study, fiber metal laminated (FML) composites were produced according to the order of 3/2 stacking by using 0.8 mm thickness 2024 T3 quality aluminum sheets, unidirectional carbon fiber fabric and epoxy resin. In the first production epoxy resin was used without additive. In the second production, graphene nano powder was added to the epoxy resin at a rate of 1%. As a result of the experiments, it was found that addition of graphene nano powder to the epoxy resin provided an increase of 9% in tensile strength and an increase of 24% in the interlaminar shear strength. The amount of permanent compressive stress in the composite increased by about 50%.

    An investigation of mechanical properties of different nanoparticle reinforced 7075-T6 Al matrix hybrid fiber metal laminated composites
    (Natl Acad Sciences Ukraine, Inst Single Crystals, 2022) Gurbanov, Nurlan; Askin, Mustafa Yunus; Babanli, Mustafa; Turen, Yunus
    The mechanical properties of a hybrid fibrous metal layered composite have been studied. Samples were obtained by hot pressing unidirectional carbon fiber fabric and epoxy resin with aluminum sheets of quality 7075-T6, 1 nun thick. In the first production, epoxy resin was used without additives. In the second production, 0.5% clay and SiO2 nanoparticles were added to the epoxy resin. Shown, that adding nanoparticles to pure epoxy resin in a laminated composite improves its mechanical properties through improved adhesive properties and crack -bridging mechanisms between fiber and nanoparticles, as evidenced by changes in the microstructure.

    Theory and Experiment in Predicting the Strength of Hybrid Fiber Metal Laminates
    (Shahid Chamran Univ Ahvaz, Iran, 2023) Babanli, Mustafa; Turen, Yunus; Gurbanov, Nurlan; Mehtiyev, Rafail; Askin, Mustafa Yunus; Ismayilov, Mahmud
    This article consists of three methodological stages. In the first one, a 3D numerical model of hybrid fiber metal laminates (FML) is developed inside ANSYS Workbench Explicit Dynamics modulus and used to predict their strengths according to the ASTM D3039M-17 standard. In the second stage, hybrid FMLs are produced according to the 4/3 stacking order in the laboratory environment, in line with the numerical model. Pure epoxy resin is initially used then reinforced with, 0.2% clay, GNP and SiO2 nanoparticles: comparative tensile tests are carried out according to the above-mentioned standards. At the final stage, experimental data, computer and theoretical (analytical) models of nanocrack formation processes in 7075-T6 Al matrix nanoparticle-filled hybrid nanocomposite materials under the influence of high-speed and quasi-static deformation regimes are investigated. It is observed that there is a 5% difference between results from simulation and experiment.
