Utilisation of veneer wastes in plywood construction from kelempayan / Muhamad Haniff Mukhtar

The goal of the study is to determine the differences in mechanical and
physical properties of plywood from veneer wastes. There are three
arrangement of core veneer which are vertical, horizontal and normal.
Kelempayan (Neolamarckia Cadamba) veneer wastes of 2.1mm thick were
used in the production of 3-ply plywood, using phenol formaldehyde and urea
formaldehyde as binders. The veneers was obtained from LKM Plywood
Industry Sdn Bhd. The off cuts of the veneers and small strips of veneers were
collected and attached by using a paper tape using veneer clipping method.
The adhesive were spread onto the veneers and pressed with a cold and hot
press at 120°C for 15 and 8 minutes respectively. The plywood was tested for
their mechanical and physical properties using the Japanese Agricultural
Standards for Plywood for bending and tensile test. The findings showed that
type of arrangement and type of resin revealed a highly significant result with
the highest strength in horizontally cut strips plywood.
