Abstract
The study is focused on electromagnetic (EM) response properties of modified bisphenol A epoxy resin, widely used in aerospace applications as paint and structural glue, enriched with a low concentration of laboratory-made arc-discharge carbon nanotubes and commercially available CVD-made single-walled and multi-walled carbon nanotubes. The EM attenuation and reflection in Ka-band (26–37 GHz) provided by fabricated samples were measured as a function of the functional filler content (1 and 1.5wt%). The constitutive parameters of nanocarbon-based composites in microwave frequencies have been reconstructed from the experimental data. The EM shielding effectiveness has been found to be strongly dependent on the nanocarbon percentage, type and synthesis conditions.
