综述了国内外短纤维复合材料注射成型过程中纤维取向数值模拟的研究成果,包括纤维取向的描述、复合体系流变模型、工艺参数对纤维取向的影响和纤维取向数值模拟状况。展望了该领域的发展趋势。
During an injection molding process of composites, fiber orientation is produced by the flow state. In this paper, the developments and achievements in research of fiber orientation are reviewed, including fiber force analysis, fiber motion, fiber orientation, influence of processing parameters on glass fiber orientation, simulation and prediction of fiber orientation, etc. Finally, brief visions were also presented.
