Abstract

In this research, the effect of preheating in nitrogen medium on acoustic properties of Walnut and white mulberry boards was studied. Sapwood boards, dimension 300×20×20 mm at green moisture content were prepared. Heat treatments were applied at 140 and 160 o C under 2 Pa. pressure for 30 and 60 minutes. Following the heat treatment, the samples were dried in a convectional laboratory kiln at 50 o C, and 50% relative humidity and air velocity of 1 m/s to the average final moisture content of 8%. Using the free vibration method on free-free bar, the dynamic modulus of elasticity and damping factor were evaluated. Results revealed that the heattreatment at 140 o C for 30 minutes did not have a significant effect on vibration properties of the wood samples. On the other hand, the heat-treatment at 160 o C caused a significant increase in dynamic modulus of elasticity and also a reduction in the damping factor of Walnut and white mulberry samples. The FTIR spectroscopy and X-ray studies showed that the degradation of cellwall polymers and increase in the crystallinity of the Walnut wood specimens occurred due to heat treatment at 160 o C.
