Delamination due to interfacial debonding between metal/composite is identified as a potential failure mechanism of fiber metal laminates (FML). In the present study, titanium based fiber metal laminate (Ti‐FML) were fabricated using different wt% of nanoclay modified epoxy as adhesive. Kevlar/jute fibers bidirectionally woven mat was used to prepare the composite layer in the laminate. The laminates produced using compression molding techniques were studied for tensile, flexural, impact load bearing capacity and adhesive strength based on lap shear and peel test following ASTM standards. Lap shear adhesive strength of nanoclay modified epoxy was enhanced to 27 MPa and interlaminar peel strength was increased to 16.8 N/mm in the laminates, when the amount of nanoclay was increased to 8 wt%. Matrix crack deflection and crack bridging due to the presence of nanoclay was identified as potential mechanism for increasing the adhesive strength of epoxy. Enhanced adhesive strength resulted in improved mechanical characteristics of Ti‐FML, exhibiting notable increases in tensile load bearing capacity at 15.5 kN, flexural peak load at 0.36 kN, and bending strength at 890 MPa, achieved with a 7 wt% increase in nanoclay content. Fiber breakage and plastic deformation of metal combinedly developed the failure deformation, load bearing and energy absorption capacity of the laminate. Hybridization of fibers kevlar/jute played a significant role in enhancing the energy absorption capacity of laminates. The developed material can find applications in aerospace structures, automotive components, and marine environments where superior mechanical performance and durability are essential.Highlights Nanoclay‐modified titanium‐based FMLs with kevlar/jute hybrid fiber mats prepared. The adhesive strength of nanoclay‐modified epoxy increased due to crack deflection and bridging, enhancing the load‐bearing capacity of the titanium FML. Improved adhesive strength controlled delamination failure in tensile and flexural tests. The laminate's impact energy absorption capacity was enhanced by nanoclay, hybrid kevlar/jute fiber composite, and titanium ductility.

“…The test results show that one of the mechanisms for the failure of titanium is the formation of adiabatic shear bands. At the same time, the lamination sequence influences the failure model of composite materials [11]. Zu et al conducted a ballistic study of composite kevlar fiber reinforced rubber composite armor (KFRRCA) using practical methods to determine the depth of penetration of KFRRCA with a diameter of 56 mm.…”

This study aims to examine the phenomena that occur due to projectile penetration on fiber metal laminate. Ballistic testing was carried out experimentally according to National Institute of Justice standards (NIJ Standard 0101.06 level III-A) using a 9 mm full-metal jacket projectile with a normal angle of attack (90° to the target). The results showed that fiber metal laminate could withstand the projectile rate by penetrating the first layer (aluminum plate) and the second layer (aramid/epoxy), while the last layer was deformed to form a bulge. The pierced aluminum plate is characterized by petalling failure. Meanwhile, the aramid/epoxy was penetrated by the projectile with failure of the primary yarn to break the fiber.

The hybrid metal/GFRP laminate is a kind of typical hybrid structure consisting of thin metal sheets and glass fiber reinforced plastic laminates, which combines the benefits of low cost, high strength, excellent impact resistance, and good corrosion resistance. In this work, a semi‐experimental method based on a nondestructive test and the analytic solution of the thin plate's deflection for the flexural and sinking stiffnesses identification of hybrid metal/GFRP laminates was proposed and validated by corresponding numerical simulations. Then, in total 17 different specimens (including metal, GFRP and hybrid metal/GFRP) were prepared and tested by the proposed semi‐experimental method to investigate their flexural and sinking stiffness performances in multiple perspectives (including stiffness per unit mass/volume/price/surface density). The analytic solutions show that the flexural and sinking stiffnesses are proportional to macro equivalent moduli of laminate specimens and proportional to the third power of thicknesses of specimens. The test results show that the stiffnesses per unit mass/density of the 7‐ply GFRP laminate can be comparable to those of the variable‐thickness rolled blank (VRB) made of steels, but the stiffnesses per volume/price of the 7‐ply GFRP laminate are only one fifth to one quarter of those of VRB. It is also found that though the hybrid metal/GFRP laminate with the combination sequence of aluminum plate/5‐ply GFRP/aluminum plate has the lowest GFRP layers' volume fraction, but has the best performances of stiffnesses per unit mass/density. Besides, the VRB part can significantly improve the stiffnesses per unit volume of hybrid metal/GFRP laminates.
