The dielectric properties are studied of composite materials based on PVC and epoxy resin filled with copper or nickel of various particle sizes and shapes. In addition, two types of particle distribution, random and segregated were produced for composites filled with nickel. The effect of the above factors on the dielectric properties of the composites was studied. The concentration dependence of the dielectric parameters is said to demonstrate a critical behaviour in the percolation threshold region, and the dependence of the dielectric parameters on concentration follows power-law behaviour. A model for the structure which explains the behaviour, is proposed. 26 refs.
