Fiber-Metal Laminates (FMLs) have become leading materials in critical industries such as aerospace due to their structural advantages, including resistance to fatigue an‎d impact, as well as a high strength-to-weight ratio. However, enhancing the mechanical properties in FML composites is always a pivotal issue for improving final performance. In this research, the main objective was the fabrication of a Fiber-Metal Laminate composite (based on commercial Aluminum 1050 an‎d simple glass fibers) using a metal phase strengthened by the Accumulative Roll Bonding (ARB) method, an‎d the investigation of its tensile an‎d flexural mechanical properties. To this end, Aluminum 1050 sheets were subjected to three complete ARB cycles at ambient temperature, which affected the metalʹs microstructure an‎d resulted in more than a two-fold increase in the yield an‎d tensile strength of the metal phase. The final composite was then fabricated by combining the reinforced aluminum layers an‎d glass fibers using the cold pressing method. For accurate eva‎luation, it was subjected to uniaxial tensile tests accompanied by the DIC system for strain monitoring, an‎d three-point bending tests. The results obtained demonstrated that the FML structure containing the three-pass rolled aluminum sheet led to the achievement of the highest ultimate tensile strength (246 MPa) an‎d also significantly improved the energy absorbed in the flexural test. Microscopic investigations confirmed that the strengthening of the metal matrix resulted in better interfacial contact an‎d stronger support for the glass fibers, an‎d ultimately showed a positive synergistic effect in increasing the composite’s ultimate strength.
