| Popis: | This study aimed to determine the influence of specific gravity on properties of oriented strand boards produced with five Eucalyptus species and get linear models between the properties and the densification of the panels. The species studied were: Eucalyptus benthamii, E. dunni, E. grandis, E. saligna, E. urograndis and the mixture between them. The panels were produced with phenol formaldehyde resin and nominal densities of 0,65 g/cm³ and 0,75 g/cm³. The water absorption has an inverse relationship to the density of the panel. The relation between mechanical properties and specific gravity of the panel is directly proportional. The panels produced with the Eucalyptus species showed better properties than those produced with control species (Pinus taeda), except for tensile perpendicular. By means of linear models obtained in this study conditions for each species, it can estimate the specific gravity to produce oriented strand board panels that adequate the standard requirements. |
