Effect of Carbon Fiber Modulus on Mechanical Behavior of Carbon Fibre Composite Rod

Abstract

Carbon fibre composite rod (CFCR) has been widely used in Aluminum Conductor Composite Core (ACCC) conductor. The mechanical properties of CFCR are related with the safety of electric power supply. The mechanical properties of CFCR are mainly determined by volume fraction of carbon fiber. Therefore, it is necessary to analyze the effect of carbon fiber fraction on the mechanical behavior of CFCR. The relationships between carbon fiber fraction and mechanical properties help to the design of ACCC conductor. This paper presents a finite element model (FEM) to analyze the mechanical properties of carbon fibre composite. The mechanical behaviors of CFCR for different carbon fiber fractions were simulated by using FEM. Based on the simulated results, the effects of carbon fiber fraction on stress and strain of CFCR under pure bending loading were revealed.
