THE EFFECTS OF SOME IMPREGNATION PARAMETERS ON MODULUS OF RUPTURE AND MODULUS OF ELASTICITY OF WOOD

Abstract

The aim of this study was to determine the effects of some impregnation parameters such as impregnation chemicals, impregnation durations, and impregnation methods on modulus of rupture (MOR) and modulus of elasticity (MOE) of Oriental beech (Fagus orientalis Lipsky) and Scots pine (Pinus sylvestris L.). Wood specimens were prepared according to TS 2470 and impregnated with chemicals for 2, 4, and 6 hours by dipping and vacuum-pressure methods. Imersol aqua, aqueous solutions of zinc chloride, and borax were used as impregnation chemicals. After impregnation, the MOR and MOE of wood specimens were determined. Results showed that the MOR and MOE of wood specimens were the lowest for the ones impregnated with imersol aqua followed by zinc chloride and borax, respectively. There were no statistically significant differences in MOR and MOE values among all impregnation durations and methods.
