复合材料细观力学的现状和展望

An Overview of Composite Micromechanies

复合材料性能优异、应用广泛、种类繁多、还会有新的发展。复合材料的定义尚未统一,这里指纤维增强塑料(FRP)。 从宏观看,复合材料是各向异性的层合材料。从细观看,复合材料是纤维和基体组成的多相非均质材料。一般认为纤维起主要的承力作用,而基体起保护纤维和传力作用,然而情况并非如此简单。 多数复合材料结构的工程问题,用复合材料宏观力学就能得到基本解决。

Composite Micromechanics, relating to the interaction of fiber and matrix, focuses on the relations between the properties of composite and its constituents.This paper provides an overview of the present regearch results in Composite Micromechanics. As two fundamental subjects, the stiffness and strength of composites are reviewed. The shear lag approach and equivalent inclusion method are introduced with their some applications.Finally,the prospect of composite micromechanics is briefly discussed.
