Impacts Of Impregnation With Imersol-Aqua On The Compression Strength Of Laminated Wood Materials

Hakan Keskin and Abdullah Togay

The aim of this study was to investigate the effects of impregnation with imersol-aqua on the compression strength of some laminated wood materials. For this aim, oriental beech (Fagus orientalis Lipsky), oak (Quercus petrea Liebl.), scotch pine (Pinus sylvestris Lipsky), uludag fir (Abies Bornmülleriana Lipsky) and oriental spruce (Picea orientalis Lipsky) wood materials impregnated with imersol-aqua according to ASTM D 1413-99 and producers’ definition. Laminated wood samples were produced from impregnated wood materials according to TS EN 386 in the form of five ply (4 mm each) from oriental beech, oak, scotch pine, uludag fir and oriental spruce wood by using desmodur-VTKA adhesive. The test samples were prepared and compression strength was measured according to TS 2595. Consequently, impregnation and lamination process increased compression strength by 1.01 % in oriental beech (BI+LW), 19.92 % in oak (OI+LW), 21.37 % in scotch pine (PI+LW), 0.39 % in oriental spruce (SI+LW) and 0.16 % in Uludag fir (FI+LW) as compared with massive (solid wood) control samples (SW). In consequence, in the massive construction and furniture elements that the compression strength after the impregnation and lamination (I+LW) is of great concern, oak and scotch pine wood materials could be recommended. ï›™ 2006 Trade Science Inc. - INDIA
