PP纤维水泥复合材料的界面行为——单纤维拉出试验初探

Interfacial Behavior of PP Fiber Cement Composites——Elementary Investigation of Single Fiber Pull - out Testing

通过普通圆截面PP、改性圆截面PP和三叶PP短纤维水泥基复合材料的拉出试验,获得了最大载荷-纤维埋入长度曲线和载荷—拉出长度曲线,并据此讨论了这类复合材料的界面行为。

The pull - out tests of plain PP, modified PP and trifoliate PP fiber have been done respectively. Two series of curves, such as maximum pull - out force versus embedded length and pull - out force versus fiber displacement, are got and the interfacial behaviors are also discussed.
