Paper Abstract

In this work a preliminary study of an ultrasound application, as a non destructive technique, for the evaluation of some chilean wood species is shown. By means of this technique the elasticity moduli (MOE) along the fibers for different positions of the samples with respect to the pith and different moisture contents are determined. At the same time the wood anisotropy properties are evaluated as the ratio between velocities along the main directions of the tree. In general, the obtained results show a high correlations between the MOE obtained by mechanic and ultrasound essays while the anisotropy values correspond mainly to the expected results. Finally, it is considered that the application of this technique as a complement to other non destructive techniques conform an excellent tool for evaluation and quality control of wood products.
