中文摘要：
通过对玻纤增强聚丙烯注射充模阶段纤维取向的研究，考虑流场和纤维取向的相互作用，基于连续介质力学理论，建立了耦合有纤维取向的薄壁制品注射充模阶段的双尺度模型，并使用有限元／有限差分／控制体积法对控制方程组进行了求解，预测结果与实际基本符合。
英文摘要：
The fiber orientation of glass fiber reinforced polypropylene is investigated during the filling stage of injection molding. Based on the macroscopic continuum equation, double-scale filling models of thin-walled cavity are established which has coupled fiber orientation, considering the interaction between fiber orientation and flow field. Then, the equations are calculated using a hybrid FEM/FDM method. The results agree with the rule of fiber orienta- tion induced by the flow.
