The electromagnetic properties of radar absorbing structure laminate composites filled with carbon nanotubes
Radar absorbing structure laminate composites composed of glass fibers,carbon fibers and epoxy resin filled with carbon nanotubes were fabricated. The complex permittivity of radar absorbing structure laminate composites was measured with free space measurement system,and the absorbing properties were simulated based on electromagnetic transmission theory. As a result of that,two optimal double-layer radar absorbing structures were obtained,the smallest reflection loss of them was -19.23dB and -26.60dB respectively,and the absorbing bandwidth was 4.2GHz and 4.0GHz separately. So,it was possible to achieve out the reflection loss was smaller than -10dB in whole 8.2-12.4GHz by adopting double-layer radar absorbing structure,adjusting to the permittivity of the composites and controlling the thickness of each layer materials.
