Friction is an important phenomenon that can dominate the resulting product geometry of thermoplastic composites upon forming. A model was developed that predicts the friction between a thermoplastic laminate and a rigid tool. The mesoscopic model, based on the Reynolds’ equation for thin film lubrication, has been validated against experiments. The tool-ply friction was characterised for 2 × 2 twill/PP (Twintex) and 8 harness satin/PPS laminates. Tool-ply friction of the latter appears to be a combination of a Coulomb type of friction and a viscous type of friction.
