Conductivity Estimation of Composite Materials Used on UAV Airframes

The problem of electromagnetic characterization of composite materials used for the airframe of aircrafts is considered. A measurement methodology is proposed for estimating the associated conductivity. This parameter is critical for the definition of antenna emplacement on the airframe keeping in mind the impact of the presence of the platform and other antenna systems on its performance. This is specially important in small size aircraft, as UAVs. Presented preliminary results are really promising. Specimens of PCN (Polymer-Clay Nanocomposite) material are used, which include metallic meshes for improving material performance against lightning.
