Effect of great size wood particles on density profile and physical -mechanical properties of particleboards made from poplar
This study was conducted to investigate the effect of mixing great size wood particles of poplar with appropriate size particles of the same species, on density profile and physical -mechanical properties of the made particleboard, this study was carried out. One layer boards were made by use of app...

This study was conducted to investigate the effect of mixing great size wood particles of poplar with appropriate size particles of the same species, on density profile and physical -mechanical properties of the made particleboard, this study was carried out.

The results obtained from measured physical and mechanical properties showed that increasing great particles ratio had no negative effect on properties of boards. Increasing the amount of this particles in boards composition, caused increasing internal bonding and decreasing water absorption and thickness swelling levels.
