Physical and mechanical characterization of Mimosa tenuiflora wood for employment in furniture industry

Abstract

The research aimed to obtain the physic mechanical characterization of Mimosa tenuiflora (Willd.) Poir. and manufacture a furniture with wood in study and to verify their aesthetic characteristics and superficial finishing. Thus, five trees of Mimosa tenuiflora had been harvested, in Brazilian Savanna (Caatinga) at Lameirão Farm, located in the municipality of Santa Terezinha, Paraíba state, Brazil, manufactured test samples and carried through physical-mechanical wood characterization in accordance with the Standard Brazilian. Assays for determination of basic and apparent densities and moisture, shrinkage and strength and rigidity to compression parallel to the fibers had been carried. For data acquisition was employed Linear Displacement Transducers (LVDTs). The values obtained in research indicated that the wood of Mimosa tenuiflora has good dimensional stability and strength and rigidity characteristics compatible for employ in furniture and small structures.
