Abstract

Wood heating is the oldest method for reducing of water absorption of wood. Today, electric heating is used to transmit high voltage current through materials using two electrodes. The aim of this study is to investigate the effect of electric shock on the physical and mechanical properties of Iranian beech wood( Fagus orientalis L). Electric shock applied to the wood samples in five different voltage and three different pressures in the reactor. The experimental design was a factorial experiment on the basis of a completely randomized design .The results show that electric shock of beech wood improves all its physical and mechanical properties. The best results obtained at atmospheric pressure and electric current of 600 volt.In this situation, Moduli of elasticity became treble and Moduli of Rapture increased 20% based on control sample. Also obtained 20 % Anti-Swelling efficiency.
