单丝复合体系界面力学行为的表征

Research progress in characterization of interface mechanical behavior of single fiber reinforced composites

摘要:

界面是纤维增强树脂基复合材料的重要细观结构,极大程度地影响着该材料的宏观性能以及破坏模式.单丝复合体系是界面力学性能表征的主要研究对象.从细观力学实验,细观力学模型以及数值模拟3个方面出发,全面地阐述了单丝复合体系界面力学行为表征的手段和方法.细观力学实验是建立细观力学模型以及发展数值模拟方法的基础,应充分利用三者的关系,建立完善的界面性能表征体系,以便更加准确的预报复合材料的力学性能,满足各个行业的要求.

Abstract:

In this paper,means and method used for characterizing the interface behavior of single fiber composite are elaborated comprehensively from three aspects:mesoscopic-mechanical test,mesoscopic-mechanical models and numerical simulation.Mesoscopic-mechanical test establishes the basis for mesoscopic-mechanical models and numerical simulation.The relationship between them should be fully utilized to establish a sound system of interface performance characterization to accurately forecast the mechanical properties of composite materials and meet the requirements of various industries.
