Abstract

In this research, nano composites of epoxy /carbon nanotube reinforced by one layer of Finemet amorphous alloy with chemical composition of  which was fabricated by planner flow melt spinning was used to investigate the electromagnetic interference shielding. X-ray diffraction test was done to characterize the Finemet amorphous alloy. Besides, vibrating sample magnetometer test was selected to measure the amount of magnetization of nanocomposites. Shielding effectiveness of composites over the X-band (8 to 10 GHz) was carried out by rectangular waveguide based on the WR90 standard. The results showed that the shielding effectiveness at X-ray band reaches 15 and 20 dB, respectively, in samples of nanocomposite of epoxy containing 0.1 and 0.5 wt.% carbon nanotube which was reinforced by one layer of Finemet amorphous alloy.
