【 摘 要 】

Wood has always been an important material for the civil construction industry and for furniture manufactures. Nevertheless, Brazil has been roted for its indiscriminate deforestation and lack of preoccupation in preservation and reclamation of the native species. The reason for this deforestation is due to several factors, among them the lack of technology in the wood industry. On top of that, the lack of knowledge of the material properties induce the users to utilise always the same species until its exhaustion. To remedy this it is necessary to promote the use of reforestation wood. The challenge is to know its characteristics and applications. The proposition of this work was to evaluate the ultrasonic methodology as a way to determine the mechanical properties of reforestation wood for classification purposes. The correlation between the results obtained in bending static tests in ultrasonic tests, using Eucalyptus citriodora and Pinus elliotti was verified. The results show that this methodology can be used in evaluation of structural pieces and indicate the viability of this method for wood classification.
