The Technology
Lightweight avionic parts such as wings and even aircraft body as well as high specific strength parts for seacrafts, automotive, wind turbine and other parts with demanding mechanical requirements are usually made of a laminate of skin which may be made of composite materials, metal sheet etc.) and a core made from honeycomb structure and / or light weight foam. For most of the above applications there is a need to increase electromagnetic wave absorbance for stealth.
Coating expanded low-density polymer microspheres withCNT, graphene or conductive materials such as nano particles shows electromagnetic shielding (at 8.2 – 12.4 GHz) of 4 – 60 dB with less than 10% electromagnetic wave reflection. In addition, the coating can increase heat conductance.
