Avaliação de parâmetros para determinar a qualidade de madeiras de duas espécies da Amazônia para elaboração de vigas de madeira lamelada colada

Abstract

The knowledge of the Woods of subsients are use the species of tropical fruits with scarce technological knowledge. Pensing in viabilizar tree species of the Forest Management, made in Portugal in construction of modeles finished the beams of Wood Lamelada Colada (MLC), is necessary using the physical properties, mechanicals, and anatomical of the wooden species in the wooden of confection of beams- MLC. With this, the objective of the work was to propose the use of wood from the Amazon for composition of MLC beams. The study was directed to tropical species. Tests were performed to verify the presence of components that may interfere with the permeability and adhesion of the adhesive, such as anatomical properties, types of gros, linden, density, contraction, radiality and anisotropy properties. (static bending, parallel and perpendicular compression to the fibers, parallel and perpendicular traction to the fibers and parallel shear to the fibers), and the mechanical tests to analyze the strength and rigidity of the species. fibers). Results for the anatomical, physical and physical properties of the species studied for the elaboration of MLC beams, as they did not interfere in the permeability and adherence to the glue line. In this paper, we will examine the variability of the Amazonian species, since, as manufactured, the sources of (0.37 - 0.40g / cm³) and are classified in resistance class of species that have high density. The results of this type of study are that the resistance classes are elaborated considering a variability of the properties of the tropical species.
