Study on preparation method of aircraft composite skin considering electromagnetic shielding

Abstract

As the airborne mission system is increasingly concentrated in a small space, airborne electromagnetic compatibility becomes worse. And the electromagnetic shielding performance of this body mechanism can be improved by blocking its radiation path. Considering the aircraft non-metallic skin properties such as strength, plasticity and resistance to corrosion, by vacuum evaporation, vacuum coating, chemical vapor deposition and dispensing under laboratory conditions and adjusting the material, layer thickness and process parameters, several examples of multiple layers of electromagnetic shielding composite materials are prepared, which has important meaning for engineering practice.
