Abstract

The aim of this study was to evaluate the potential use of sisal and coir fibers in combination with Eucalyptus particles for the production of particleboard. The particleboards were produced in three layers. The first and third layers (face) were made with small Eucalyptus particles. The second layer (core) was made with big Eucalyptus particles in combination with coir or sisal fibers. The particleboards were prepared with the substitution on Eucalyptus wood for sisal and coir fibers in the particleboards core, in doses of 0, 10, and 20%, relative to the total mass of particles. The particleboards were characterized by mechanical, physical and thermal properties. The results were not satisfactory for particleboards with sisal. However, for coir particleboards the physical-mechanical properties were very similar to those particleboards produced only with Eucalyptus. This work demonstrates the potential use of the coir that is commonly disposed in landfills on the Brazilian beaches.

Highlights

Wood boards can be defined as compounds of elements of the breakdown products of wood, such as plates, laths, particles and fibers, which are surface coated with an adhesive to produce the boards
The Medium density particleboard (MDP) are an evolution of the chipboards, by having three layers, two layers with smaller particles in the faces and one layer with bigger particles in the core of the board
The moisture ranged from 9.43 to 9.80%. Both those properties showed a slight variation of the mean values

Summary

Introduction

Wood boards (or wood panels) can be defined as compounds of elements of the breakdown products of wood, such as plates, laths, particles and fibers, which are surface coated with an adhesive to produce the boards. These new products are known as reconstituted wood products and their properties are different from the original wood material[1,2,3]. The MDPs are an evolution of the chipboards, by having three layers, two layers with smaller particles in the faces and one layer with bigger particles in the core of the board They are usually produced with wood particles, and they are mainly used in the furniture industry. The use of natural fibers as reinforcement has aroused great interest in developing countries because of their low cost, availability, energy saving, renewable source, non-toxic and with regard to environmental issues[18,19,20]
