The problem of electromagnetic shielding of civil aviation aircraft is perceived by leading manufacturers of unmanned aerial vehicles as one of the most important problems regarding composite elements. There is a need to provide protection against electromagnetic interference in order to effectively protect navigation and telemetry devices against the impact of strong electromagnetic fields generated by some actuators of such ships. The solution is based on a mixture of appropriately selected polymers, one of which has the properties of an electrical conductor, and the other is a dielectric with very good strength and process properties. This combination allows to obtain a material with good mechanical strength and electrical conductivity. Additionally, the polymer mixture is reinforced with carbon fiber, which is intended to both improve mechanical strength and create additional electrical conduction paths by connecting conductive polymer particles dispersed in the dielectric polymer. The solution is dedicated to the unmanned aircraft industry in order to shield against electromagnetic radiation elements that generate a strong electromagnetic field that may interfere with the operation of navigation and telemetry devices.
