Abstract :Normal 0 21 false false false TR X-NONE X-NONE i In this study, in wood laminated with pinus insert ignore into journalissuearticles values(A); and poplar insert ignore into journalissuearticles values(B); sawed veneers, the effects of formation of different layers on the bending and adhesion strengths have been investigated. For this purpose, veneers with a thickness of 3 mm are sawed from pine insert ignore into journalissuearticles values(Pinus silvestris L.); and poplar insert ignore into journalissuearticles values(Populus tremula); woods and lamination layers are designed as AAAAAAA, BBBBBBB, ABABABA, ABBABBA and ABBBBBA. As an adhesive only polyvinylacetat insert ignore into journalissuearticles values(PVAc); is used in the layers paralel to the grain. To the experiment samples prepared, a bending strength test and a binding strength test are condueted on the bases of DIN 52 186 and DIN 53 255 respectively. As a result, the bending and binding resistance as well as the density of laminated wood have been increased depend on pine layers. From the point of resistances performance on the laminated wood are observed to increase depending on the pine layers.  Key Words: Laminated wood, symmetry of layer, poplar, pinus
