界面力学性能的研究方法有多种,如直接法、间接法、有限元法等,而单丝模型法是一种简便而又直观的方法。 在纤维增强的聚合物基复合材料中,一根纤维或一束纤维及其包围在外面的基体是最基本的单元,亦是最小的宏观性能试样。这种以一根纤维及其包覆在纤维外面的基体组成的模型称作单丝模型。单丝模型不但可以用来研究这种基本单元的力学性能,而且可以用来估价表面处理剂和处理方法,以及各种界面状态,还可以用此模型来研究其界面的微观机理,并 There are many research methods for the mechanical properties of interface, such as direct method, indirect method, finite element method, etc. The monofilament model method is a simple and intuitive method. In fiber-reinforced polymer-based composites, a fiber or a bundle of fibers and their surrounding matrix are the most basic units and are also the smallest macro performance samples. This model consisting of a fiber and its matrix coated on the outside of the fiber is called a monofilament model. The monofilament model not only can be used to study the mechanical properties of this basic unit, but also can be used to evaluate the surface treatment agents and treatment methods, as well as the various interface states. It can also be used to study the microscopic mechanism of the interface and
