Abstract

With the development of aviation industry, the performance requirements of aircraft materials are increasing day by day. Carbon fiber composites are widely used in aircraft structures because of their excellent mechanical properties and lightweight properties. However, the inherent weak electrical conductivity of the carbon fiber composites poses challenges to the safety of the aircraft in the lightning strike environment. Therefore, enhancing the electrical conductivity of carbon fiber composite material and improving its lightning protection performance has become the focus of current research. The paper deeply analyzes the structure and mechanical properties, conductivity mechanism, and the influence of interface effects on conductivity of carbon fiber composite materials. It explores various technical means to enhance conductivity and lightning protection techniques, in order to provide theoretical basis and technical support for the design and application of carbon fiber composite materials.
