In this work, AC electrical properties of epoxy composites based on carbon black (CB) were determined depending on the loading of filler. The measurements were carried out within a frequency range 20 Hz – 1 MHz. The loading of carbon black was 0–5 wt.% in composites. The conductivity increased when increasing the content of carbon black and the maximum values were observed at 5 wt.% CB. The maximum value of permittivity was at 0.75 wt.% CB and it can be considered as percolation threshold.
