RESUMO

ABSTRACT The objective of this study was to evaluate the technical viability of Cordia trichotoma and Grevillea robusta wood for the production of plywood panels, as well as to verify the behavior of these species in combination with Pinus taeda and Eucalyptus saligna. Panels were produced using veneers of each species and in combination, totaling 8 treatments. The panels were glued with urea-formaldehyde using grammage of 180g/m2; pressed at a temperature of 110 °C, with pressure of 1MPa and a pressing time of 8 minutes. The results of the density, moisture content, superficial and total water absorption, static bending and shear tests of the core, face and back-face veneers, indicated the viability of Cordia trichotoma and Grevillea robusta for the production of plywood for interior purposes using all veneers of these species, as well as, in the production of decorative plywood manufactured using Pinus or Eucalyptus veneers.
