In the last decades a new class of materials named fiber/metal laminates (FMLs) has been introduced. It is a hybrid composite material which has both low weight and good mechanical properties, simultaneously. The mechanical properties of FML show improvements over the properties of both Aluminum alloys and composite materials individually. In this study, bending properties of this material are investigated numerically and experimentally. Composite layers have a very limited formability and the deformation of fibers is pure elastic. Hence, the fibers cause some kind of springback after deformation that is larger than that of the metal alloys which is known as a defect. In an experimental method, six specimens were prepared with variable fiber angles for bending test. The experimental results show that when the fibers are parallel to the bend line (no fiber deformation), the metal parts (layers) dominates the minimum bend radius and spring-back angles for thin laminate (up to 1.5-2.2 mm). As Finite Element method is a suitable method to decrease the design expenses, the results of this study is also compared with numerical data.
