Abstract

With the increasing demand for lightweight and performance improvement of aircraft materials, lightning protection safety has become an important issue in structural design. This article focuses on the application of composite films in aircraft lightning protection, starting from the optimization of material conductivity, and comprehensively analyzing the influence of structural parameters on the conductivity path and film performance. By designing the thickness, interface structure, and material arrangement of the film layer reasonably, the composite film has significantly improved its current dispersion and shielding ability while ensuring mechanical strength. The optimization results show that structural design plays a key role in improving the overall lightning protection function of composite films, providing theoretical basis and technical support for the innovation and application of aviation and aircraft safety protection materials.
