ABSTRACT Fiber metal laminates (FMLs) are composite materials with growing importance in the automotive and aerospace industries due to their potential for combining benefits of metals fiber‐reinforced polymers. However, interlayer bonding strength remains a critical challenge affecting overall performance. This study explores novel strategies enhance interfacial mechanical properties FMLs using nanomaterials surface treatments. Graphene nanoparticles (GNPs) silicon dioxide (Silica) were incorporated as nanofillers, while ultrasonic shot peening (USP) anodic oxidation (AO) used The assessed flexural properties, shear strength, interlaminar fracture toughness treated FMLs. GNPs/AO method increased ultimate strain by 53.4%. Silica/USP combination proved most effective enhancing modulus improvements 69.6% 83.3%, respectively. Silica/AO achieved highest increase 168.9%. synergistic combinations improving Modes I II GNPs/USP, achieving 1969.35 1786.36 J/m 2 , Scanning electron microscopy (SEM) optical analyzed damage patterns enhancements at glass fiber/epoxy resin (GF/EP) aluminum plate/epoxy (AL/EP) interfaces. Molecular dynamics (MD) simulations showed Silica GNPs significantly raised energy dihedral angular interaction energies. Nanofillers improved fiber‐resin contact modifying functional group distribution interface.
