Özet

The aim of this study was to investigate the effects of impregnation with Imersol-Aqua (I-AQUA) on the modulus of elasticity in bending of some woods. For our study, Oriental beech (Fagus orientalis Lipsky), oak (Quercus petrea Liebl), Scotch pine (Pinus sylvestris Lipsky), Uludag fir (Abies Bornmülleriana Lipsky), Oriental spruce (Picea orientalis Lipsky), and poplar (Populus nigra L.) wood samples were prepared according to TS EN (Turkish Standards; European Norm) 408 and impregnated with I-AQUA by the method of short-, medium-, and long-term dipping according to ASTM D 1413 and producers' definition. After the impregnation process, modulus of elasticity was measured according to TS EN 408. Consequently, among the nonimpregnated wood samples, modulus of elasticity was found to be the highest in Oriental beech (Fagus orientalis Lipsky), (12,490 N mm-2) and the lowest in poplar (5439 N mm-2). As for the period of dipping, the highest modulus of elasticity was obtained in short-term dipping and the lowest in long-term dipping. Considering the interaction of wood type and period of impregnation, the highest modulus of elasticity in bending was obtained in Oriental beech (Fagus orientalis Lipsky) with short-term dipping (10,720 N mm-2) whereas the lowest was in poplar with long-term dipping (4597 N mm-2). In consequence, in massive constructions and furniture elements where the modulus of elasticity in bending after impregnation is of great concern, short term impregnation of Oriental beech and Scotch pine materials could be recommended. © 2006 Wiley Periodicals, Inc.
