The Effects Of Impregnation With Imersol-Aqua On The Bending Strength Of Some Softwood And Hardwood Materials

Musa Atar, Hakan Keskin

The aim of this study was to investigate the impacts of impregnation with imersol-aqua on the bending strength of some solid wood materials. For this aim, 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 Lipsky) wood samples were prepared according to TS EN 408 and impregnated with Imersol-aqua by the method of short, medium and long-term of dipping according to ASTM D 1413 and producersÂ’ definition. After the impregnation process, bending strength was measured according to TS EN 408. Consequently, among the non-impregnated wood samples, bending strength was found to be the highest in oriental beech, (138.617N.mm-2) and the lowest in poplar (61.021N.mm-2). As for the period of dipping, the highest bending strength was obtained in shortterm dipping and the lowest in long-term dipping. Considering the interaction of wood type and period of impregnation, the highest bending strength was obtained in Oriental beech with short term dipping (118.404 N.mm-2) whereas the lowest was in poplar with long-term dipping (53.510 N.mm-2). In consequence, in the massive constructions and furniture elements that the bending strength after the impregnation is of great concern, short term impregnation of Oriental beech and Scotch pine wood materials could be recommended.
