Abstract

In this work, the electrical conductivity and physical and mechanical properties of composites based on liquid thiokol filled with technical carbon grade K-354 were studied. The aim of this work was to obtain an inexpensive electrically conductive composite using a thiokol matrix. It was found that the addition of carbon black to the thiokol matrix leads to a significant change in electrical conductivity, so with an increase in the content of carbon black in the composite material from 20 to 40 m.p., there was a regular decrease in the specific electrical volume resistance from 1.28×104 to 2.34×10 (Ohm×m) occurred. Using scanning electron microscopy, the structure of the surface of the composites and the distribution of particles in the composite matrix were studied. With an increase in the filler content, the packing of aggregates in the matrix becomes denser, which contributes to closer contact between carbon black particles, thereby creating conditions for the formation of electrically conductive chains. The resulting composite can be used as an electrically conductive sealing material.
