The Investigation on Feasibility of Oriented Strand Boards to Parquet Production from Mixed Residual Veneer Popular and Beech

The objective of this study was to investigate of feasibility of using residual veneer (popular and beech) to manufacture oriented strand board (OSB) parquet. Percentage of mixed residual veneer popular to beech was 40%to 60% respectly. In this study press time (6، 8 and 10 min) and press temperature (170º، 180º) were selected as variables، other factors being kept constant. Results indicated that increase of press temperature had no significant effect on modules of rupture، modules of elasticity and hardness but had significant effect on internal bonding، water absorption and thickness swelling. However results indicated that increase of press time had significant effect on total physical and mechanical properties of boards.
