摘要: 为确保架空导线用碳纤维复合芯棒在电网中的安全稳定运行,提高其性能检验技术,借助三维绘图和有限元等软件对碳纤维复合芯棒的拉伸断裂破坏形式进行了仿真分析。结果表明,模拟与试验结果相近,碳纤维复合芯棒拉伸时破坏首先发生在碳纤维层,然后是玻璃纤维层,破坏的主要形式为分层崩裂。研究结果可为碳纤维复合芯棒制造工艺、试验方法、工程应用等提供技术理论支撑依据。

Abstract: In order to ensure the safe and stable operation of power grid which uses carbon fiber composite cores in overhead conductors, and improve the performance testing technology, simulation analysis is made on the tensile failure mode of carbon fiber composite core with aid of 3D drawing and finite element software, which shows that the tensile failure occurs firstly in the carbon fiber layer, then in the glass fiber layer, and mainly in the form of delamination. The simulation result is very close to the testing result. This study results can provide technical & theoretic support for manufacturing process, testing method and engineering application of the carbon fiber composite core.
