Resumo: | This work aimed at evaluating 15 provenances of Eucalyptus cloeziana, Eucalyptus grandis and Eucalypotus saligna for multilaminated plywood boards manufacturing. Six boards for each provenance were made. Phenol-formaldehyde adhesive with 320g/m² glue content was used. The utilized pressing cycle was of 15kgf/cm², at the temperature of 150ºC during 10 minutes. From the results obtained regarding the physical properties, the species of Eucalyptus cloeziana and Eucalyptus saligna performed better. In the mechanical tests, MOE presented itself above the demands of the norm with the exception of provenance 7785 of Eucalyptus saligna, in which stress was performed parallel to the cover fibers. For parallel MOR, only the provenances 9789 and 10695 of Eucalyptus grandis and 97852 of Eucalyptus cloeziana managed to reach the demands of the norm ABNT 31:000.05-001/2. For shearing stress and failure in wood, all the provenances and species showed themselves above the demands, with the exception of 10634; 48 and 9753 of Eucalyptus grandis. |
