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%.

 

Keywords: Empty fruit bunch; natural fibre; tensile properties

 

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
