EXPERIMENTAL RESEARCH ON ELECTRICAL PROPERTIES OF PARTICLE REINFORCED COMPOSITE MATERIALS AS CANDIDATES FOR VARIOUS INDUSTRIAL APPLICATIONS

Abstract

The paper summarizes the experimental research conducted on metallic (Fe) particle reinforced polymer composite samples in order to retrieve few of their electrical properties. The particles considered were embedded into an epoxy matrix, having different dimensions and the same fraction volume (0.7). Frequency variation impedance measurements on the samples shown an unusual behavior of these types of composite materials and revealed a dielectric nature for the overall composite. Comparison with the theoretical models and statistical analysis completes the studies. Example calculation demonstrates the effect of varying filler volume fraction, intrinsic material properties, particle shape and frequency. Potential applications already identified, previously and during the studies, for this class of materials will provide enough working space for all involved and interested in developing and characterizing novel materials.
