摘要：

Composite materials are increasingly used in modern commercial aircraft skin. However, the poor conductivity makes it necessary to have additional conductive structures to ensure the current flow in the skin. In order to improve the conductivity of the skin and reduce the influence of the bonding between the composite material and the conductive structure on the current path, the skin structure was modeled based on the electrical characteristics of each component structure, and the construction process that may affect the bonding was analyzed by using the analytical method. In view of the changes in the current in the contact surfaces and the overall structural impedance caused by different construction processes applied at different parts of the skin, the influence of the construction process of each structure during assembly on the electrical characteristics of the aircraft skin bonding structure was analyzed. Theoretical analysis and simulation results show that the appropriate construction process, especially the correct treatment of the resin and oxide film of metal connection on the skin surface, can effectively reduce the influence of overall structural impedance on the electrical performance of the skin and provide some operational suggestions in site-oriented construction. © 2024 Beijing University of Aeronautics and Astronautics (BUAA).
