| Summary: | This study used Acacia mangium and rubberwood species as the raw
materials in manufacture of oriented strand board (OSB). The objectives of
this study were to determine the physical and mechanical properties of OSB
using Acacia mangium and rubberwood, and effect of different board densities
(600 kg/m3 and 700 kg/m3
) and wood species ratio on properties. In this study,
phenol formaldehyde (PF) was use as a binder and it was fixed at 9%.
Oriented strand board was assessed for the mechanical properties (bending
and internal bonding) and physical properties (thickness swelling) according to
European Standard (EN 300: 1993). Mechanical properties revealed the
highest MOR (34.18 MPa) and MOE (6 835.78 MPa) with higher board density
of 700 kg/m3 from 100% Acacia mangium. However, the highest results for IB
value was 1.32 MPa from L4 layer with lower board density of 600kg/m3
.
Furthermore, for the physical properties with density board of 600kglm3 with
100% Acacia mangium strands point the lowest TS value with 27.24%. The
results revealed that board density show significant effect on mechanical
properties except for lB. However, TS values were not significant. |
