Abstract :In this study, it was aimed to determine whether or not the  layer organizations were influential on the expansion in volume after keeping in water for 2 hours, on the bending strength and modulus of elasticity values of laminated veneer lumber insert ignore into journalissuearticles values(LVL);. Austrian pine insert ignore into journalissuearticles values(Pinus nigra); insert ignore into journalissuearticles values(A); and Lombardy poplar insert ignore into journalissuearticles values(Populus nigra); insert ignore into journalissuearticles values(B); veneers with thicknesses of 3 mm were used for the production of laminated veneer lumber. A total of 110 test specimens with 8 different layer organizations were prepared by using polyvinyl acetate based insert ignore into journalissuearticles values(PVAc-D4); adhesive. Solid Austrian pine and Lombardy poplar woods in the same dimensions were used as control specimens. At the end of the tests; the bending strength and modulus of elasticity values of all the LVLs with different combinations were found to be higher compared to the control specimens. The strength characteristics of the LVL increase as the percentage of Austrian pine increases . Key Words: Lamination, Laminated Veneer Lumber insert ignore into journalissuearticles values(LVL);, Bending Strength, Modulus of Elasticity, PVAc Adhesive.
