Abstract
The electrical properties of carbon black-epoxy resin composite materi als were studied in the frequency range between 100 Hz and 15 Mhz. We have determined the critical exponents which describe the behaviours o f conductivity and of the dielectric constant, near the percolation th reshold, as functions of the frequency. The experimental values of the critical exponents are in agreement with those given in the literatur e.
