COMPARATIVE ANALYSIS OF PHYSIC AND MECHANICAL PROPERTIES OF TEAK WOOD (Tectona grandis L.F.) FROM QUEVEDO AND BALZAR

It was studied the physical-mechanical properties of the wood Teak (Tectona grandis L.F.) coming from Quevedo and Balzar. The objectives were: to determine the heartwood and sapwood percentage of the trees, the physical properties in green and anhydrous state of the wood, the mechanical properties in balance state and the main physical-mechanical differences of the wood. In Quevedo five trees of 22 years old teak were collected and in Balzar five trees of 18 years old teak were collected. Of each tree two logs of 2.50 m of long was obtained and of each log a central plank of 10 cm of wide by 2.50 m of longitude was obtained of which beams was extracted and finally the specimens. 60 specimens were elaborated (six specimens for tree) for the rehearsals of the physical properties. For the study of the mechanical properties 60 specimens were elaborated (one for each rehearsal for tree). The methodology used for the study of the physical and mechanical properties was based in the norms ASTM D 143-94 (American Society for Testing and Materials). The results showed that significant difference doesn't exist among the wood of the two areas. The wood of Teak of Quevedo and Balzar presented medium density, for what has better use possibilities in the production of furniture and cabinets, external uses, molds, parquet and floors in general, carpentry in general, boardings, doors and windows, agricultural tools and vehicles, among the main ones.
