Abstarct: Fiber mextal Laminates (FMLs) are one of the more applicable composite sheets that consist of mextal laxyers and fiber-reinforced. These laxyers are joint to each other with a resin bond (epoxy or polyurethane). In the present study, the experimental and numerical investigation of springback in hat-shaped section bending have been performed. At first, the two types of FMLs were produced with aluminum 2024-T3 and 1050-O sheets, unidirectional E-glass fibers and polyurethane resin by using a hot press at 170 °C and pressure of 10 bar. The specimens produced according to the lay-up in 0º and 90º direction of mextal laxyers and fiber-reinforced core, then the hat-shaped channel bending was performed. The effects of parameters such as FML lay-up, channel depth and core thickness on springback angles in the horizontal and vertical zones were studied. In the numerical section, by using Abaqus software, the parameters such as thickness distribution in FML and equivalent plastic strain in AA2024-T3 laxyers and the springback of FML with laxyer of AA2024-T3 with different lay-up were investigated. In this section, the mextal laxyers were modeled as an elastic-plastic material with quadratic Hill's anisotropy criteria and the core laxyer was assumed as an orthotropic linear elastic material. The experimental results of FML with AA2024-T3 laxyer showed that the springback of the channel is independent of mextal laxyers direction when the fibers are in the longitudinal orientation, while the fibers are in the transverse direction, the mextal laxyers orientation has not significant effect on the springback. Furthermore, the springback angles of FML with AA1050-O laxyers are significantly less than that of FML with AA2024-T3 laxyers. By increasing the final thickness, the vertical springback angle decreased monotonically, while the horizontal angle increased at first and decreased finally. The comparison between numerical and experimental observation showed a desirable agreement of FML geometry after unloading.
