Finger-jointing of green Eucalyptus globulus L. wood with one-component polyurethane adhesives

Abstract The use of glued finger joint in green wood, directly from the sawing process, would open possibility to obtain timber small-sized achieving an efficient original raw material. gluing finger-jointed with moisture content above fibre saturation point, may improve efficiency and manufacturing process glulam or joinery. This be especially beneficial for a hardwood such as Eucalyptus globulus L., which is globally important forest resource, but challenging wood dry. article presents study on develop joints state. To compare them, conventional dry solid boards without end were also manufactured. Cold-setting fast-curing commercial one-component polyurethane adhesive systems used. Finger-jointed samples tested determine mean characteristic values (5th percentile) density, bending strength modulus elasticity, results analysed discussed. Green-glued showed no statistically significant differences compared improved properties respect dry-glued joints.
