摘要：
Based on the three-dimensional model, a finite element model for warpage simulation of fiber-reinforced polymer thin-wall injection-molded parts was established simultaneously considering wall slip and pressure dependence of viscosity in this work. The effects of model dimension, wall slip, and pressure dependence of viscosity on the warpage simulation of injection- molded parts were analyzed. The influences of main process parameters on the maximum warpage deformation of injection-molded parts were subsequently discussed. The results show that the model dimension has the greatest influence on warpage simulation, followed by the pressure dependence of viscosity, and the wall slip has the smallest influence on warpage simulation; the maximum warpage deformation of injection- molded parts increases with the increase of injection rate, melt temperature and mold temperature, while it decreases significantly with the increase of holding pressure and changes slightly with the increase of holding time. © 2023 Chengdu University of Science and Technology.
