| مستخلص: | Studies of the technological properties of little-known native species are essential for an indication of sustainable management of the Amazon. The study aimed to evaluate the physical-mechanical performance of five Amazonian species obtained from an area managed in the Amazon by a non-destructive methodology, and to indicate their use to manufacture EGP panels. The samples were obtained from non-flooded secondary forest in the Amazon/Brazil (EEST/INPA). Fifteen trees were selected to determine the physical-mechanical properties, using the microwave system to determine the moisture, the apparent density test and the dynamic modulus of elasticity (MOEd). The microwave system presents better drying performance when compared to the conventional method (artificial drying), considering that the dry woods in this system present greater stability in the equilibrium moisture, and the woods from Murici, Breu vermelho and Angelim pedra presented content close to 12%, ideal moisture for EGP manufactures. The apparent density of the woods varied from 0.76 to 1.18 g.cm-3, classified as high density, following the standards of tropical woods. The studied woods presented MOEd of 11,175 to 14,109 MPa, thus demonstrating good resistance, and lower risk of deformation for the different uses, including for EGP panels, whether structural or not, being necessary to consider the type of adhesive. The quality of the studied woods presents a promising result for industrial indication, since they are mostly unknown or non-commercial woods, where technological characterization is a key tool to assist in decision making in the forest management plans that may indicate the use of new species in the forestry sector. |
