Abstract
Binderless panels were manufactured from the particles of bark, leaves, fronds, middlepart
and core-part of oil palm trunks at two different target densities (0.8 g/cm3 and 1.0
g/cm3) using two different pressures (5 MPa and 12 MPa). Binderless panels produced
were tested for the physical and mechanical properties. Chemical analysis had also been
conducted including determination of extractives, holocellulose, alpha-cellulose, lignin
content, starch content, individual sugar, and total sugar content in oil palm fibers.
Spectroscopic characterization was done using Fourier Transform Infrared (FT-IR)
spectroscopy to detect the presence of the functional group that exists in oil palm fibres
before and after the board was made. The anatomical features of the raw materials and
the manufactured panels were viewed using Field Emission Scanning Electron
Microscopy (FESEM). The results showed that panels produced from core portion of the
trunks exhibited the highest Modulus of Rupture (MOR) and internal bond (IB) strength,
but lowest thickness swelling (TS) and water absorption (WA) values among the
samples. Some of the tested panels had met Japanese Industrial Standards (JIS A- 5908)
for the Type 8, Type 13 and Type 18. However, panels made from bark and leaves did
not have satisfactory strength and dimensional stability. Based on the results of this
study, oil palm biomass could be considered as environmentally friendly alternative raw
material for the manufacture of binderless particleboard.
