Technological characterization of juvenile wood teak (Tectona grandis) to production of furnitures

Abstract

This work aimed to characterize technologically the teak wood (Tectona grandis) obtained from thinnings and assess their potential for making furniture. The woods were from of three trees with approximate age of seven years removed from a plant in the municipality of Guarapari, ES, Brazil. The wood analyzed showed basic density of 0.45 g cm-³ and shrinkings of 2.72, 6.17 and 9.84% (radial, tangential and volumetric) with anisotropy coefficient of 2.22. On the basis of these results and ones of the assays of static bending and compression parallel to grain the tested wood can be used in the manufacture of small furniture. For resistance to wood dry termite (Cryptotermes brevis), were tested samples and heart and sapwood, with heartwood stronger than the sapwood. Generally speaking, wood was ranked as moderate resistance to wood dry termite attack. The teak wood young showed easy workability, machining and finishing. The furniture (table) manufactured attend the aesthetic characteristics and desired finish, adding value to the product from the first thinning, considered a residue and employed for purposes with less added value.
