The application of fiber-metal laminates (FMLs) has long attracted attention in the aerospace industry, with most studies focused on aluminum-based systems such as GLARE. However, the growing deman‎d in the automotive industry for advanced materials combining high strength an‎d low weight has shifted interest toward steel-fiber laminates. This study investigates steel-fiber composites an‎d compares their performance with aluminum-fiber composites. Experimentally, two types of steel-fiber laminates with different metallic layer thicknesses were examined against aluminum-fiber laminates under nearly identical weight an‎d bending stiffness at two impact energy levels. Numerically, the damage mechanisms were modeled using Abaqus to simulate the experimental tests, with additional simulations conducted for curved specimens. Results show that steel-fiber an‎d aluminum-fiber laminates with comparable bending stiffness exhibit similar displacement responses an‎d performance under impact. For curved laminates, decreasing the curvature radius reduces peak load while increasing contact duration.
