纤维增强混凝土的拉拔性能试验研究

Experimental research on pulling performance of fiber reinforcement concrete

界面是复合材料重要的微观结构,而单纤维拔出试验常用来测定纤维复合材料的界面性能。通过对钢纤维混凝土的单个纤维的拔出力和拔出位移的测定,得到了典型纤维拔出力和拔出位移之间的关系曲线,分析了纤维拔出过程中的受力情况。

Interface is an important microstructure of composite materials,and single fiber pull-out test commonly used to determine the interface properties of fiber composites.This paper obtains the relation curve between pullout force and pull-off displacement of typical fiber and analyzes the force condition during pull-out of the fiber through the determination of pull-out force and pull-out displacement of single fiber of steel fiber reinforcement concrete.
