Description

The logarithmic law of mixtures can be suitably extended to form equations which can describe the dielectric behaviour of polymeric composites containing non conductive fillers. The proposed equations can give the permittivity and loss of the composites as a function of the permittivities of the constituents, the volume fraction of the inclusions and their aspect ratio, The proposed equation are tested with experimental data obtained in a wide range of frequency and temperature from composites with epoxy resin and Kevlar fibres. Satisfactory agreement is observed and existing discrepancies must be attributed to the intrinsic weakness of the logarithmic law of mixtures on which the proposed equations are based. (EN)
