Abstract

The rate of global deforestation and its impact on the environment has led particle board manufacture to search for alternative feedstock, especially in countries where wood is less available compared to other cellulosic natural product. Based on the properties of coconut fibre and PET bottle, these two materials can be recycle as raw material for manufacture of panel board. As for this study, the coconut fibre were used as the filler and PET bottle as outer lining of the panel board. Two types of coconut fibre were used which are grinding and un-grinding coconut fibre. At first, the coconut fibre are undergoes softening, grinding, drying and sieving process, while PET bottle was cleaning, shredding, sieving before compacted using hydraulic hot press machine. There are four types of testing that been carried out which are swelling, water absorption, Modulus of Elasticity (MOE) and Modulus of Rupture (MOR). The result show the conventional board has the highest value for MOE test, so it’s indicate that the conventional board is less strength from the coconut fibre board. As for water absorption test, the average water absorption of coconut fibre based panel board is less than conventional board. Overall, the coconut fibre board is better than conventional panel board because coconut fibre board are less swelling, has low water absorption, high modulus of rupture and low modulus of elasticity. Based on the finding, this coconut fibre panel board has potential as a stronger and long-lasting panel board than the conventional board in the market. Other than that, the panel also have their own aesthetic value since the recycled plastic bottle used as outer lining is colourful and giving aesthetic value.

Highlights

The use of renewable resources such as agriculture residues is gaining increase interest in production of particle board
Undergoes the finishing process the sample were tested according to the standard test applied on the panel which are modulus of elasticity, modulus of rupture, swelling and water absorption
This method of testing is used to determine the coconut fibre with grinding process, the coconut fibre with un-grinding process and standard panel board behaviour under an axial stretching load

Summary

Introduction

The use of renewable resources such as agriculture residues is gaining increase interest in production of particle board. Coconut is a renewable resource and a natural fibre extracted from the husk of coconut and used in product such as floor. Coconut fibre known as coconut coir is a fibrous material extracted from the husk of coconut. The coconut fibre is separated from the husk by mechanical method even though it’s can be separated using chemical and biological method [1]. Coconut fibre is the hardest natural fibre because high content lignin in coconut fibre up to more than 30 % that make the fibre tougher and stiffer by providing plant tissue and individual fibre with compressive strength and stiffen the cell wall of the fibre in order to protect the carbohydrates from chemical and physical damage [3]. The value density of coconut fibre is important to determine the total mass needed to produce the coconut fibre panel board
