| Abstract: | Bending experiments were performed on non-consolidated and consolidated specimens of single-layer unidirectional fiber reinforced thermoplastic composite in molten condition. The results exhibit distinctive bending behaviour. The consolidated specimens portray reduction in stiffness and a higher viscosity, compared to non-consolidated specimens. Micrographs of the specimens were created before, during and after bending. Consolidation influences the micro-structure of the material by making the fiber-matrix distribution more homogeneous, eliminating most of the surface roughness and removing nearly all voids. This influence remains visible after deconsolidation and bending. Currently, material models of bending behaviour used in simulations of stamp forming, are based on characterization experiments of non-consolidated specimens. However, consolidated laminates are the input of stamp forming. It is thus advised to review the material characterization of the bending deformation mechanism. |
