Abstract
Polymer composites using natural fibres as the reinforcing agents have found their use in many applications. However, they do suffer from a few limitations, due to the hydrophilicity of the natural fibres which results in low compatibility with the hydrophobic polymer matrices. This paper presents the alternative low-cost methods of sugar palm (Arenga pinnata) fibre surface treatments to improve the fibre-matrix interfacial adhesion. Fibre surface modifications were carried out by water retting process where the fibres were immersed in sea water, pond water and sewage water for the period of 30 days. The results showed that the tensile and flexural strengths of the treated fibre reinforced composites increased as the fibre treatment duration increased. This indicates that the treatments had significantly improved the fibre-matrix bonding strength.
