模内层压工艺中层压材料的可成形性

he in-mold lamination process is a new and potential process for plastic products. Taking the case of a support of the auto inner door panel, the forming-ability of the laminated material is analyzed, from the points of the mechanical properties of laminated material, processing parameters and mold structure. An experiment of single axis stretch is carried out to obtain the mechanical data and model of the laminated material (PVC). Then, the explicit dynamic finite element method based on LS-DYNA is used to simulate the lamination process of PVC, with discussing the effects of processing parameters and mold structure on the final quality.
