| Summary: | This researchs main objective is to evaluate the quality of Eucalyptus grandis manufactured
plywood for external use. In order to make comparisons, plywood of Pinus taeda and Araucária angustifolia
were also manufactured, using phenol-formaldehyde resin with two formulations. The plywoods of
Eucalyptus grandis showed higher specific gravity and lesser thickness reduction in comparison with the
other two species. The results of shear bonding tests were statistically the same between all species. The
values of MOR and MOE of Eucalyptus grandis were statistically the same in comparison with Araucaria
angustifolia and higher than Pinus taeda. In relation to effects of different formulations of adhesive, no
differences for all evaluated properties were verified excluding water soaking shear bonding test. |
