Abstract

Background. The aim of the study is to discover the dependence of the percentage ratio of polyethylene to carbon, carbon black of two grades to each other and the effect of this ratio on the results of resistance and stability of samples. The topic is relevant, since recently there has been a rapid development of power engineering, microelectronics, science, and the development of self-healing fuses is possible on the basis of systematic studies of the electrophysical properties of composite materials. Materials and methods. The resistor element of composite resistors is a heterogeneous system consisting of several phases: carbon black, polyethylene, and additives. Results and conclusions. The results of the study of polymer-carbon composites based on high density polyethylene and two grades of carbon black are presented. The dependence of the percentage of polyethylene to carbon black on changes in the resistance of the composite material has been established. The research results are confirmed by experimental data. Conclusions. As a result of the study, the influence of an increase in the concentration of polyethylene on an increase in resistance was revealed, as well as the effect of an increase in the concentration of low-resistance carbon black of the UTVO25 grade to high-resistance carbon black UTVO31 on the stability of the characteristics of samples without a large spread of resistances.
