Determination of relationship between density and some physical properties in beech and poplar wood

Solid wood material has used in many different areas from the past to the present day. In particular, it has many outstanding features such as being easy to procure, cheap, easy to process, attractive from aesthetic standpoint. It is known that wood species, moisture content, wood type (juvenile wood-mature wood or heart wood-sap wood) and wood imperfections are effective on wood properties. In this study, the relationship between physical properties and density of wood were determined. For this purpose, experiments carried out on beech (Fagus orientalis L.) and poplar (Populus x euramericana I-214) woods. In the experiments, the oven dry density of wood, swelling percentages, fiber saturation point and moisture content were determined. TS 2470, TS 2471, TS 4083 and TS 4084 standards were used in the experiments. The relationships between oven dry density and other physical properties were determined by regression equations. These relationships showed by distribution graphs. According to findings; it was determined that as the amount of oven dry density increased, the percentage of swelling increased and the percentage of moisture content decreased
