Abstract

In this investigation, 36 laboratory medium density fiberboard (MDF) panels were produced using Alder wood fibers. Variables factors were steaming time ( 5, 10 and 15 minutes), press time (4 and 6 minutes) and resin consumption (9 and 11%). The physical and mechanical properties of panels were measured and analyzed. The results indicated that the maximum MOR was observed panels produced applying 6 minutes press time and resin consumption of 11%. The maximum Internal Bonding (IB) was related to panels made employing steaming time of 15 minutes and resin consumption of 11%. However, test panels produced at 6 minutes press time showed minimum of thickness swelling. The results indicated that the MDF boards produced from alder wood fibers exhibit desirable physical & mechanical properties were above than EN standard requirement. Consequently application of alder wood fibers to improve physical & mechanical properties of MDF panels which are produced from nonwood materials and agricaltural residues is recommended.
