摘要摩擦是一种重要现象，它可以主导热塑性复合材料成型时产生的产品几何形状。开发了一个模型来预测热塑性层压板和刚性工具之间的摩擦力。基于薄膜润滑雷诺方程的介观模型已通过实验验证。对 2 × 2 斜纹布/PP (Twintex) 和 8 综丝缎/PPS 层压材料的工具层摩擦进行了表征。后者的工具层摩擦似乎是库仑型摩擦和粘性型摩擦的组合。
ABSTRACTFriction 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.
