dc.description.abstractShortage of wood as a raw material has coerced wood based industries to find alternative local raw materials, and oil palm biomass appears as the most viable alternative. This work was based on the studies of converting oil palm trunk (OPT) and oil palm empty fruit bunches (OPEFB) into new plywood and to analyze their properties. Five-ply hybrid plywood (oil palm trunk veneer and empty fruit bunch mat was arranged alternately) with different spread levels (300 g/cm2 and 500 g/m2) of resins (phenol formaldehyde and urea formaldehyde) were prepared. The mechanical, physical and thermal properties of the plywood were studied. The mechanical properties, such as bending strength, bending modulus and screw withdrawal of hybrid plywood showed better mechanical properties than oil palm trunk plywood. Plywood made using phenol formaldehyde showed better properties compared to plywood made using urea formaldehyde. The swelling thickness and water absorption of oil palm trunk plywood were higher than that of hybrid plywood. The swelling thickness and water absorption of the plywood made using phenol formaldehyde were better than that of plywood made using urea formaldehyde. The thermal properties of the plywood panels were determined through thermogravimetric analysis (TGA). The panels glued with phenol formaldehyde with a spread level of 500 g/m2 showed better thermal stability as compared to the other panels. The delamination test showed that the samples of hybrid plywood with glue spread 300 g/m2 using urea formaldehyde exhibited the highest delamination while plywood made using phenol formaldehyde samples showed no delamination. Scanning electron microscopy (SEM) was used to study the fiber matrix bonding and surface morphology of the plywood using different glue spread levels of the resins. The fiber-matrix bonding showed good improvement for the panel glued with 500 g/m2 for both resins.en_US
