Forming processes of thermoplastic composite sheets required heating and cooling, therefore a spring-back phenomena will be occurs. The springback behavior after V-bending of glass fibre reinforced polypropylene (GFRPP) compositesheets under different forming temperature (40, 60, 80 and100) oC and fiber content ratio (0,10,20,30,40) %wt. were investigated. The simulation of springback in composite sheets by finite element method was made for accuracy. This study shows asthe forming temperature is increased the springback and springback factor (Kf) suppresses. When the fiber content is increased the springback angle and springback factor (Kf) decreases, while mechanical properties is increased.
