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.
