OSB, beech, poplar, veneer, thermal conductivity


The aim of this study is to investigate the physical and mechanical properties of OSB boards whose surfaces are covered with wood veneer. In the study, veneered OSB boards were produced with a final thickness of 18 mm using poplar and beech veneers. Phenol formaldehyde and urea formaldehyde glues were used as glue. Air dry, oven dry and wet densities of the veneered OSB boards produced were determined. On the other hand, 2, 24 and 72 hours water absorption and thickness swelling properties were determined. Bending strength and mod-ulus of elasticity testing of the veneered OSBs produced was carried out. The water absorption and thickness swelling resistance of veneered OSB boards produced using PF glue gave better results than those produced using UF glue. It has been determined that gluing the veneers with the fiber directions perpendicular or parallel to each other has no effect on the density. It has been understood that veneered OSBs produced using beech veneers generally exhibit better mechanical properties than veneered OSBs produced using poplar veneers. It can be said that covering the surfaces of OSBs with veneers affects the thermal conductivity value negatively and other physical and mechanical values positively. In order to increase the usage areas of veneered OSBs, it is recommended to conduct new studies using different wood species and glues.
