Abstract
This paper presents a novel test set-up to characterize the bending behavior of UD laminates in thermoforming conditions. An analysis of the set-up and the applied boundary conditions is presented. A validation of the test procedure using purely elastic specimens, shows its potential to accurately measure bending properties, to be used for numerical forming simulations. Preliminary bending tests were performed on UD carbon PEEK specimens, showing a visco-elastic response. The actual bending phenomenon is confirmed to be intimately related to the intra-ply shear deformation mechanism.
