Determination of the Elastic Modulus of Particleboard by Stress Wave Timer

ABSTRACT

The objective of this study was to evaluate the determination of the elastic modulus of particleboard by stress wave timer and associate the results with the effect of some production variables of the panels. The experiment consisted in five treatments: four treatments produced with sugar cane bagasse, where two types of adhesives (melamine-urea-formaldehyde - MUF and urea-formaldehyde - UF) were evaluated in combination with two types of panel structures (layered and homogeneous); and one treatment produced with UF adhesive, with structure in layers and with Eucalyptus urophylla wood. It was possible to observe that the type of material is what influences the most on the determination of MOEd, with the panel of sugar cane bagasse presenting the best correlations. The type of adhesive had no effect on the results, while the panels with layered structure tended to have better correlation in relation to the homogeneous panels.
