The Bending Strength Of Medium Density Fibreboard (MDF) From Different Ratios Of Kenaf And Oil Palm Empty Fruit Bunches (EFB) Admixture For Light Weight Construction

摘要

The use of alternative materials from agriculture and plantation bio-mass has widely been researched especially for use in bio-composites. These bio-mass have been used in flour form as fillers, in fibre form as reinforcements and in both flour and fibre forms as bulking agents. These bio-mass not only enhanced the composites but also help to reduce the burden on natural fibres from the forests. Furthermore, these bio-mass fibres can be used as an alternative or supplementary raw material in composites such as fibre glass-polymer composites by replacing part of the synthetic fibres, if not all, depending on the final application of the finished composites. Combining one material with other materials provides a strategy for producing advanced composite materials that take advantage of the properties especially bending strength of both types of resources. It allows the researcher to design materials based on end-use requirements within a framework of cost, availability, recyclability, energy use, and environmental considerations. This paper reports on the bending strength of MDF from kenaf, oil palm EFB, and from admixtures of EFB and kenaf in different ratios. Production of composite material from these diversified resources will not only help to reduce the pressure on natural forests, it is also an alternative to overcome waste disposal problems in palm oil industries. The results indicate that kenaf and EFB could be mixed to produce MDF. The panel produced can be used for furniture components such as table tops and shelves, wall partitions and door panels.
