Abstract
Fiber metal laminates (FMLs) are a special type of composite structure consisting of metal sheets bonded to composite laminas. The current study investigated the effect of the replacement of cross-ply (0/90◦) glass fiber reinforced epoxy laminas with woven glass fiber reinforced polyester laminas in GLARE laminates on the tensile, bending and interlaminar fracture toughness of the laminate. Test results showed that the existence of woven glass fiber laminas increased the tensile strength with a decrease in corresponding strain, the flexure strength decreased significantly due to the existence of polyester instead of epoxy resin, and the mode I interlaminar fracture toughness increased. ABAQUS® software was used to simulate the tests, and ductile damage was employed to detect the failure of aluminum layers, the Hashin failure criteria to model the failure of composite layers in the laminate, and the cohesive surface interaction to capture delamination between layers.

1. Introduction Fiber metal laminates (FMLs) consist of metallic layers such as sheets of aluminum alloy, steel, and/or titanium that are bonded to layers of fiber matrix. FMLs combine the characteristics of embedded metallic layers and fiber laminas. Aluminum is the most widely used metal for FMLs, and the fibers could be kevlar, carbon, and/or glass. FMLs with glass fibers (trade name GLARE), and Kevlar fibers (trade name ARALL) had been evaluated for potential applications in aircraft structures due to weight saving and increased strength [1-4]. Accordingly, FMLs are attractive hybrid materials for lightweight, fatigue-critical structural applications. Many researchers have investigated FML responses due to tensile, bending, and interlaminar fracture toughness over the past few decades by experimental, analytical, and numerical approaches. The presence of the ductile metallic la
