| 摘 要： | 利用自行研制的先剪切后拉伸的挤管口模,对3种不同配比的HDPE6100M/HMWHDPE共混物挤出管材的周向、轴向强度进行研究,实验中发现少量的HMWHDPE有利于HDPE管材在复合引力场挤出中实现力学性能的双向自增强,预示了少量的HMWHDPE有利于诱导HDPE6100M分子沿应力场方向取向、结晶。

| Abstract: | The polymer melt was sheared first and then drawn by a self-made extrusion die.Three HDPE6100M/HMWHDPE copolymers were extruded through the die,and circumferential and axial strengths of pipes were studied respectively.It was shown that the few HWMHDPE added HDPE was favorable to obtain self-reinforced pipes prepared under this complex stress field,which indicated the addition of few HMWHDPE to HDPE contributed HDPE6100M molecular orientation and (crystallization) along the stress direction. |

| Keywords: | complex stress field self-reinforcement in two directions pipes |
