EVALUATION OF THREE WOOD SPECIES FROM DRY FOREST FOR THE PRODUCTION OF EDGE GLUED PANELS – EGP
EGP, wood species from dry forest, adhesives test
The demand for wood products promoted the improvement of the technique of glued wood. Among the innovative alternatives of this technique stands out the wood panel glued laterally or Edge Glued Panel (EGP). The wood used as raw material for the manufacture of this type of panel is usually obtained from trees with small diameter. In order to study species of the Caatinga that present potential technological properties for the production of EGP panels and to provide information about the potentialities of use of the wood species of the biome, the present research had the objective of analyzing the technological characteristics of the wood of Cordia oncocalyx Allemão, Aspidosperma pyrifolium Mart. and Mimosa caesalpiniifolia Benth, as well as evaluating bonded joints and comparatively evaluating species for the production of edge glued panels. For this, analyzes were carried out on the physical-chemical properties of the wood, shear test of the bonded joints according to EN 1334: 2003, as well as percentage of failure in the wood according to the procedures described in ABNT NBR ISO 12466- 1: 2006. The physicochemical analyzes of the species were evaluated using the Tukey test at 95% probability level. Results obtained in the analysis of the basic wood density and the extractive content showed statistical differences among the species and no statistical differences were found between species in the analysis of ash content. Concluding that among the three species, Mimosa caesalpiniifolia Benth may be the species with the greatest difficulty in edge bonding.
