Improving the Properties of Pineapple Leaf Fibres by Chemical Treatments

Abstract

Natural fibres such as pineapple leaf fibre (PALF) have the advantages of low density, lightweight, low cost, biodegradability and renewability. Recently, many research works have been conducted all over the world on utilization of natural fibres as a reinforcing material for composites for variety of applications. Nonetheless, the inherent lack of good compatibility of natural fibre towards the polymer matrices limits the utilization of natural fibre for reinforcing agent in composites less attractive. For that reason, chemical treatments are considered in modifying the fibre properties which aimed at improving the compatibility of fibre and the polymer matrix. Chemical treatments of PALF can help clean the fibre surface, modify the surface and increase the surface roughness. Ultimately, moisture absorption is reduced in the treated fibre reinforced composites which results in enhancements of mechanical properties. In this article, effect of chemical treatment on the properties of PALF and PALF-reinforced polymer composites is discussed and different chemical treatment with their functions is listed. Recent studies dealing with chemical-treated PALF-reinforced composites have also been cited.
