Abstract: Composite plates containing pine wood particulates and high density Polyethylene (PE) matrix were prepared using thermo-compression and characterized by Electrical Impedance Spectroscopy (EIS) measurements at room temperature and under frequency interval of 40-100 kHz for different wood contents ranging from 40-70%. The double-DCE (ZARC) Model was used as equivalent circuit for the obtained plates. The impedance parameters of this model such as intracellular Resistance (Ri), extracellular Resistances (Re1 and i Re2 ), relaxation time (τ1 and τ2 ) and the distributed coefficient of the relaxation time (Ψ1 and Ψ2 ) were determined for the different specimens. Effects of pine powder concentration on interfacial compatibility within the composites were analyzed. The relaxation time increased with increasing wood contents up to 50% and decreased at higher rates. This finding suggests that the optimal interfacial compatibility in wood powder/polyethylene chips composites without additives is attributed at 50% wood contents.
