Abstract
The purpose of this article is to compare the electromagnetic absorption properties of carbon fiber layer composite materials produced separately using Au particles doped MWCNT added epoxy with pure MWCNT added epoxy resin. This new material, produced using MWCNT doped with Au particles, increases its radar absorption capability. And therefore the as-prepared electromagnetic absorber demonstrates enormous potential in future military and aviation applications. Multilayer composite materials, consisting of Au/MWCNT doped epoxy, MWCNT doped epoxy and pure epoxy, were produced by vacuum infusion method. Electromagnetic absorbing properties of the produced materials were determined with the Agilent brand 2-Port PNA-L Network Analyzer device by conducting transmission/reflection measurements in the frequency range of 3–18 GHz. The electromagnetic absorbing properties of the produced composite materials were taken in two different measurements, both with and without metal plate. Measurements were made using two horn antennas. Show that the produced MWCNT doped and Au/MWCNT doped carbon fiber laminated composite material has good absorption behavior when used with metallic sheets and is good for RADOM applications at many points at 3–18 GHz.
