Particleboard Manufactured with Bamboo and Coconut Fibers in Different Ratios of Adhesive

This research aimed to develop and evaluation the mechanical properties of a particleboard produced with bamboo particles and coconut fiber in three different experimental conditions. The panels were manufactured with castor oil based polyurethane bi-component resin in three different ratios of the adhesive components (pre-polymer and polyol). Mechanical characterization was conducted to determine modulus of elasticity (MOE) and modulus of rupture (MOR) in static bending. For the static bending test the better values were to the experimental condition 2, which relate de proportion of 1:1.5 of pre-polymer and polyol, respectively. This best solution is to reduce the amount of pre-polymer in the formulation of the adhesive, due to decreased of use of chemicals most polluting.
