Résumé
Diversity of vibration properties of ten tropical hardwoods covering wide range of densities and anatomical structures was investigated. Wood from tilted trees was included in the study to examine the intraspecific diversity along with the interspecific one. Moreover, the relation with structural parameters (basic density, microfibril angle) was studied. While the variability of the elastic modulus was in great part explained by the variations of basic density and microfibril angle, damping coefficient was not correlated to structural parameters. This was particularly true for reaction woods and therefore attributed to the intensive loading history likely leading to the formation of microcracks.
