Abstract

Shungite is considered as a filler of composite materials. It is a natural composite of carbon nanoparticles with a variety of micro- and nano-sized mineral impurities that give it high conductivity and electromagnetic radar-shielding properties. The radar-absorbing and shielding characteristics of a composite material based on fine shungite and urea–formaldehyde resin are studied in the 500 MHz to 4 GHz range of frequencies. The effect the thickness of a sample has on the electromagnetic properties of the studied composite is determined.
