摘要
半晶聚合物复合材料,尤其是纤维增强的半晶聚合物复合材料,在其界面区常有横晶结构生成。本文综述了横晶自发现至今的研究情况,对横晶的形成和生长机理进行了描述,对影响横晶生成和性质的因素进行了分析,着重介绍了几种典型半晶聚合物复合材料体系的横晶形态,并讨论了横晶对界面特性和复合材料性能的影响。
In semi_crystalline polymer composites, when heterogeneous nucleation occurs with sufficiently high density along the interphase region, the resulting crystal growth is restricted to the lateral direction, so that a columnar layer develops around the fiber, known as transcrystallinity (TC) or transcrystalline layers (TCL). The advance in the study of TCL in some fiber reinforced semi_crystalline polymer composites is reviewed in the present paper. It includes the formation and growth mechanisms of TCL, and the influences of TCL on the interfaces of fiber/polymer and properties of composites.
