Effect of the Diameter Ratio on the Flexural Stress of Carbon Fibre Composite Rod

Abstract

Carbon fibre composite rod (CFCR) is an important part during the design of Aluminum Conductor Composite Core (ACCC) conductor. CFCR is used to improve the bearing capacity in order to make sure the safety of electric power supply. The flexural failure of CFCR could lead to the outage of electric power. Therefore, it is important to investigate the flexural behavior of CFCR. The diameter of CFCR and the diameter of wheel have a great effect on the flexural failure of CFCR. This paper presents a finite element model (FEM) to analyze the stress in CFCR under flexural loading. Based on the proposed FEM, the effect of diameter ratio on the flexural stress of CFCR is analyzed. Using the calculated results, the variation of flexural stress with the diameter ratio is obtained. These conclusions would help to design Aluminum Conductor Composite Core (ACCC) conductor.
