Caracterização físico-mecânica da madeira cumaru (Amburana cearensis) para a aplicação em mobiliário.

Abstract

The sustainable usage of wood has been target of researches, that aims the preservation of biomes that are about to disappear. Among them it can be cited the Caatinga as a meaningful example. The reforestation, employing native species of each region is one of the main solutions for the decrease of exploration of forest reserve. The main objective of this work was to study the physical-mechanics characteristics of Cumaru wood (Amburana cearensis), a kind of species provided by the biome Caatinga. The physical-mechanics properties were determined following the recommendations of the Brazilian Standard Regulatory: Design of timber structures (NBR 7190/1997). The following tests were performed: determination of the moisture content, basic and apparent density, dimensional stability and determination of resistance and stiffness compression parallel to the fibers. The results indicate that Cumaru wood can be employed in structures, in furniture and other pieces of construction.
