| Summary: | This study evaluated the physical and mechanical properties of a hybrid board
consisting of rice husk and rubberwood fiber by varying the ratios of rice husk
and rubberwood fiber. Currently rubberwood supply is decreasing and limited
in resources thus another agriculture waste species were promoted as very
promising raw material for wood composite product. The objective of this study
are to determine the physical and mechanical properties and evaluate the
suitable ratios for hybrid board. The hybrid boards were manufactured from
three different percentage of ratios of rice husk and rubberwood fiber (50:50,
25:75 and 75:25) and the target board density was 650 kg/m3 with applied 12%
of Phenol Formaldehyde (PF) as a binder. The hybrid board quality were
evaluated by determine of bending properties including modulus of rupture
(MaR), modulus of elasticity (MOE), internal bonding (IB) strength. Thickness
swelling (TS) and water absorption (WA) based on JIS A5905:2003. The
results show that the bending strength and internal bonding were decreasing
with the increasing of percent of rice husk in the board. The result for thickness
swelling also show the same result. But the water absorption was increasing
with the increasing of percent of rice husk in the board. |
