【 摘 要 】

Carbon fibre composite rod (CFCR) has been widely used in Aluminum Conductor Composite Core (ACCC) conductor. CFCR is usually under flexural loading during the operation of electric power. Therefore, the flexural properties of CFCR are related with the safety of electric power supply. The failure of CFCR could lead to the outage of electric power. Therefore, it is of importance to analyze the mechanical behavior of CFCR under flexural loading. The material of CFCR is transverse isotropy, which is different from isotropy material. The available finite element models (FEMs) are based on isotropy material. It is unreasonable to use these FEMs to predict the mechanical behavior of CFCR. This paper presents a new FEM to analyze the mechanical properties of transverse isotropy materials. Using the proposed FEM, the mechanical behaviors of CFCR under flexural loading are obtained.
