摘要: An equivalent circuit model has been developed to describe the impedance response of composites with insulating or conductive particles fibers. Required inputs are matrix conductivity, “intrinsic conductivity” particles, and their volume fraction. The general applicability systems involving moderately matrices, particles/fibers, and, in case conducting presence a high “coating” element on particle surfaces. Ramifications for use spectroscopy characterization composite properties monitoring performance under load discussed.
