Thermal and electrical properties on three basic planes of Mangium wood (Acacia mangium Willd) with different trunk position

Abstract

Wood was very complex lignocellulose materials due to its anisotropic property. In this work, the objective was to analyze and determine the effect of wood orientation of Acacia mangium wood on thermal and electrical conductivities, dielectrical constant and impedance property by using Stefan Boltzman method. The results showed the relationships between thermal and electrical conductivities in Acacia mangium. The highest thermal conductivity value was in the cross section plane at the bottom of the tree. In contrary, the highest electrical conductivity value was in tangential plane. These differences were expected due to anisotropic property of wood which is influence thermal and electrical properties.
