摘　　要：介绍了短纤维－热塑性聚氨酯弹性体（SF－TPU）注射充模过程国内外的研究进展，SF—TPU注射充模过程与通常高聚物有许多相似之处，更有其不同特点。国内外的研究者们对其注射充模过程中的传热、流动、纤维取向与加工条件、模腔几何参数之间的关系进行了研究，但纤维与流体的相互作用、前锋流对纤维取向的影响等，还须进一步研究。The advance in injection molding of short fiber (SF)-thermoplastic polyurethane (TPU) was reviewed with 42 references. SF m TPU injection molding was similar to that of general polymers, but it also had its own characteristics. The relationships between heat transfer, flow, fiber orientation andprocess conditions in SF-TPU injection molding were studied by many researchers, but the interrelation between fiber and flow, the effect of front-flow on fiber orientation in injection molding should beresearched further.
