ABSTRACT
The use of natural fibres obtained from plants and
trees as reinforcing materials has attracted many researchers to widen their
applications. Natural fibres are low cost, low density, have high specific
properties, biodegradable and non- abrasive. Oil palm fibre (OPF) can be obtained
directly from natural resource, it is cheap and also has advantages due to its
renewable nature, low cost, and easy availability. In this study, the
mechanical performances of single oil palm fibre are measured and evaluated.
The diameter of OPF was in the range from
250 to 610 μm while moisture content was between 2.2 to 9.5%. The average
tensile properties obtained were tensile strength, 71 MPa, Young’s modulus,
1703 MPa and elongation at break, 11%.

ABSTRAK
Penggunaan gentian
semulajadi daripada tumbuh-tumbuhan dan pokok sebagai bahan penguat telah
menarik minat ramai penyelidik untuk digunakan secara meluas dalam pelbagai
aplikasi. Gentian semulajadi
mempunyai kos yang rendah, ketumpatan rendah,
mempunyai ciri-ciri spesifik yang tinggi, mudah terurai dan tidak pelelas.
Gentian kelapa sawit (GKS) boleh didapati secara
terus daripada sumber semulajadi, murah dan mempunyai kelebihan berdasarkan
sifatnya yang boleh diperbaharui, kos rendah dan mudah
di perolehi. Dalam kajian ini, ciri mekanikal bagi gentian
kelapa sawit tunggal telah diukur dan dinilai. Hasil
cerapan diameter GKS adalah
antara 250 hingga 610 μm dan kandungan lembapan adalah 2.2 hingga 9.5%. Ciri ketegangan yang diperolehi adalah kekuatan ketegangan,
71 MPa, modulus Young, 1703 MPa dan pemanjangan pada takat putus, 11%.
Kata kunci: Ciri ketegangan; gentian semulajadi;
tandan buah kosong sawit tunggal
