ABSTRACT
Radar absorbing structure laminate composites composed of glass fibers, carbon fibers and epoxy resin filled with carbon nanotubes were fabricated. Two optimal double-layer radar absorbing structures were obtained, the smallest reflection loss of them was -19.23 dB and -26.60 dB respectively, and the absorbing bandwidth was 4.2 GHz and 4.0 GHz separately. It was possible to achieve out the reflection loss was smaller than -10 dB in whole 8.2 - 12.4 GHz by adopting double-layered radar absorbing structure, adjusting to the permittivity of the composites and controlling the thickness of each layer materials.
