摘　　要：本研究采用真空压力浸渍成型工艺,将芳纶/聚酯纤维混合编织物卷绕到模具中,在真空压力的作用下,用环氧树脂体系对编织物进行浸渍,经高温固化后制得芳纶绝缘拉杆,并对该绝缘拉杆管材和成品进行物理性能、力学性能和电性能的检测,利用工业CT对其微观结构进行扫描分析。结果表明:制备的芳纶绝缘拉杆内部结构密实,树脂浸渍充分,界面结合性、力学性能和电气绝缘性能良好,完全满足252 kV GIS的使用要求。The aramid/polyester fiber mixed fabrics were rolled into a mold by using vacuum pressure impregnation and molding process. The mixed fabrics were impregnated with epoxy resin system under vacuum pressure,and then an aramid insulated tension pole was prepared after curing at high temperature.The physical properties,mechanical properties and electrical properties of the insulated tension pole tube and the finished product were tested,and its microstructure was analyzed by industrial CT.The results show that the aramid insulated tension pole has dense internal structure,sufficient resin impregnation,good interface adhesion,mechanical properties and electrical insulation properties,which fully meets the application requirements of 252 kV GIS.
