摘　　要：试验试件由聚丙烯塑料栓钉、塑料板通过螺纹连接而成。为了测定聚丙烯塑料螺纹节点在轴心受力下的强度,将试件在万能试验机上进行拉拔试验,得到不同螺纹长度的试件的破坏形态以及螺纹节点轴心拉力与螺纹长度之间的关系。The purpose of this project is to determine the strength of polypropylene thread joints under axial stress.The test specimen is made of polypropylene plastic peg and plastic plate connected by thread.After drawing test on universal test machine,the failure pattern of specimen with different thread length and the relationship between axial tension and thread length of thread joints are obtained.

关 键 词：聚丙烯 螺纹节点 轴心拉力
