| Abstract: | The influence of size and shape of rice husk on the physical and mechanical properties of rice
husk/wood composite was studied. In this work, rice husk was used as supplementary raw material
mixed with wood particle at 50:50 ratio for composite panel manufacture, 7 percent isocyanate/urea
formaldehyde resin adhesive systems with the ratio 3:4 of isocyanate to urea formaldehyde was
employed. Modulus of Rupture (MOR), Modulus of Elasticity (MOE), Internal Bond (IB) and 2 h
water soaking of rice husk/wood composite were tested. The results showed that the MOR, MOE, IB
and thickness swelling of rice husk/wood composite made with rice husk of 20 mesh, 30 mesh,40 mesh
were comparable with those of wood particle board and met the Chinese National Standard For Wood
Particle Board respectively, and the 20 mesh rice husk results in the best quality. |
