| description | Mechanical, Physical and Screw Withdrawal Properties of Engineered
Wood Structure bounded with 12% urea formaldehyde added with
hardener (Ammonium Chloride) has been studied. The board combination
of laminated veneer lumber and particleboard were fabricated with three
different sizes i.e <1 mm, >1mm and mixture from below and upper than
1mm. The boards produced was evaluated for its modulus of
rupture(MOR), modulus of elasticity (MOE), internal bonding (IB), water
absorption (WA), thickness swelling (TS) and Screw Withdrawal properties
which is screw withdrawal (SW) in according with Malaysia Standard. The
diameter of screw used in the study is 7mm while the thread angle is 30'.
The screw withdrawal testing was made on two position which are the
surface (Laminated Veneer Lumber) and edge (Particleboard). The study
revealed that the >1mm shows the best screw withdrawal strength. The
best orientation on face in laminated veneer lumber substrate compare to
orientation on edge in particleboard substrate, for mechanical properties
mixed particle size shows the best strength of bending strength, <1mm
particle size has high internal bonding strength and for physical properties
<1mm particle size is the best result compared to <1mm and mixed
particle size. |
