Properties of plywood from rubberwood, eucalyptus pellita and mix tropical species / Nik Muhamad Hazim Nik Mohd Adib

Plywood is from wood based product is a composed of three or more thin layer
of wood that are glue together one or more veneers from parallel and
perpendicular for both side of a veneer and united under high temperature and
pressure. The shortage of wood as a raw material has recently to great
concern. Therefore we must find wood based industries new raw material give
alternative sources of local raw material and the plantation with fast growing
such as rubberwood and Eucalyptus tree currently appears to be alternative
substitute for plywood industry. The rubberwood and Eucalyptus is a fast
growing plant and can be often use at a considerable cost between mix tropical
wood. The cost of rubberwood and eucalyptus is only about half or little from
tropical wood the price used for structural purpose. This study investigated the
plywood on the mechanical properties of different plywood using different
species at the plywood. The measured mechanical properties include panel
shear, modulus of rupture (MOR), modulus of elasticity (MOE) and bonding
shear at face, middle and back. The plywood made from Eucalyptus give a
lower quality compare than mix tropical and rubberwood. This happen due to
the density of eucalyptus is lower than compare with rubberwood and mix
tropical wood. The results indicated the density lower give the properties of
plywood from Eucalyptus is decrease. For plywood from rubberwood is almost
the same result with the plywood mix tropical, it happen because the density
of rubberwood is nearly same the density of mix tropical wood. Rubberwood
can be considered as appropriate material for plywood manufacturing.
