| Abstract: | A joint simulation method was established on the basis of the Moldflow and ABAQUS softwares to analyze the warpage of overmolding injection-compression molded PMMA/PC composite panels.The numerical simulation of the warpage was carried out through a two-step method.The filling,packing and cooling stages during the overmolding in-jection compression molding process were first analyzed by the Moldflow software.The temperature field of the demol-ded part and the grid file obtained from the Moldflow analysis were then imported into the ABAQUS software to calcu-late the warpage when the composite panels were completely cooled to room temperature after demolding.The warpage resulting from the stress release and complete cooling were linearly added to obtain the final value.Meanwhile,the war-page of the part was measured through an injection-molding experiment.The results indicated that the joint simulation was in good agreement with the experimental results. |
