Properties of neolamarckia cadamba plywood made with phenol formaldehyde (PF) resin / Siti Kamilah Junaidi

Junaidi, Siti Kamilah (2016) Properties of neolamarckia cadamba plywood made with phenol formaldehyde (PF) resin / Siti Kamilah Junaidi. [Student Project] (Unpublished)


This study is about plywood manufacturing using fast growing species, which
is Kelempayan and phenol formaldehyde resin was used as a bonding agent
to attach the veneers together. This project focused on the old and new
Kelempayan and veneer layout. The veneer was exposed to the surround
environment within 1 month is considered as new veneer, while the old
veneer is considered once it undergoes 3 months exposure to humidity.
Veneer layout is classified into four different types which is all 3-ply
Kelempayan, 3-ply tropical, core ply Kelempayan and core ply tropical
veneers. Several tests following JAS 2014 were applied to the board
(plywood), which were bending test (Modulus of Elasticity, MOE and Modulus
of Rupture, MaR), tensile test and wood failure test. The result of
Kelempayan age (exposure), shows that new Kelempayan veneers gave a
better performance as compared to the rest of plywood boards. The highest
performance of bending is 8019MPa (MOE) and 59MPa (MOR), for tensile
test, 3.25MPa and 33% in wood failure test. For veneer arrangement, the
best combination is core Kelempayan when it showed the highest value for
MaR (69.43MPa) and 6.5% in wood failure test. For MOE of bending test, all
3-ply tropical plywood showed the highest value of 8964MPa and for tensile
test 3-ply Kelempayan plywood was strongest with the value of 3.82MPa
