Over the last decade, polymers reinforced with natural fibres composites have been
getting an increasing attention from the academic world and various industries.
Natural fibres are prospective reinforcing materials and their usage until now has
been more traditional than technical. The attractive features of natural fibres are their
low cost, lightweight, high specific modulus, renewability and biodegradability. Oil
palm empty fruit bunches (OPEFB) are readily available in large quantities in palm
oil mills. The fact is oil palm fibre (OPF) can be obtained directly from natural
resource, cheap and also has advantages due to their renewable nature, low cost, and
easy availability. This study was aim to determine the tensile and flexural properties
of oil palm fibre-thermoset composites. Oil palm fibre/phenol formaldehyde
(OPF/PF) composites and oil palm fibre reinforced epoxy (OPF/Epoxy) composites
were fabricated to carry out the determination of mechanical properties. The
composites were prepared by volume fraction of 40%, 50% and 60% for OPF/PF
while for OPF/epoxy were 5%, 10%, 15% and 20%. Composites were cut based on the ASTM D638 for tensile testing and ASTM D790 flexural testing. The testing was
conducted on a Universal Testing Machine while the interfacial adhesion between
fibre and matrix were observed using the scanning electron microscopy (SEM).
Results from tensile and flexural tests of OPF/PF composites showed an increasing
trend of tensile and flexural strengths as the volume fraction of fibre was increased.
From the scattered values, it is found that the highest tensile and flexural strengths
for OPF/PF composites were obtained at 60% volume fraction, in average. The
results of tensile and flexural tests for OPF/Epoxy composites showed that by the
addition of fibre content, the tensile and flexural strength was decreased compared to
pure epoxy resin (0% fibre). It has been notice that to obtain the optimum tensile and
flexural properties was found at the volume fraction of 5%. It is also found that the
dispersion of fibre and interfacial adhesion between fibre – matrix can affect the
mechanical properties of the composites. |
