| 摘 要： | 纤维复合材料本身具有强烈的结构特性,是一种多相体材料.
其力学性能及损伤破坏规律不仅取决于各组分材料性能,同时也取决
于细观结构特征,采用细观力学分析建立材料宏观力学性能与材料各
组分性能以及细观结构参数之间的内在联系是材料科学发展的新趋势.
本文结合作者的研究课题综述了纤维增强脆性材料(主要是纤维混凝
土)细观机理的部分研究进展,并对这一学科的发展趋势进行了简要
地评价与展望.

| Abstract: | As a heterogenous material, fiber-reinforced composites (FRC) have a significant structural mechanism. The mechanical behaviour and failure machanism of FRC depend significantly on its meso-structure and the properties of each constituent. It is a new trend to study the relationship between the macro-mechanical behaviour and the properties of the constituents as well as the meso-structual parameters. In this paper, some developments in the mechanism of strengthening and toughening of FRC, mainly for fiber-reinforced concrete, are reviewed. In addition, the developing trends of this subject are discussed. |
