Density and longitudinal dynamic modulus of three angiosperm woods impregnated with boron

The objective of the investigation was to determine the densities and dynamic modules with longitudinal vibrations, before and after applying the impregnation treatment based on boron salts to wood from Spathodea campanulata, Fraxinus americana and Albizia plurijuga. For each species, 40 specimens w...

Gaia:The objective of the investigation was to determine the densities and dynamic modules with longitudinal vibrations, before and after applying the impregnation treatment based on boron salts to wood from Spathodea campanulata, Fraxinus americana and Albizia plurijuga. For each species, 40 specimens were impregnated with the hot-cold bath method and the corresponding retentions were determined at concentrations of 1%, 2% and 3%. Wood densities do not change after treatment. The densities before treatment were 351 kg m-3 for S. campanulata, 654 kg m-3 for F. americana and 830 kg m-3 for A. plurijuga. The dynamic modules of F. americana and A. plurijuga did not vary by treatment. A different case is S. campanulata whose dynamic modules did vary. The dynamic modules before treatment were 4765 MN m-2 for S. campanulata, 13303 MN m-2 for F. americana and 16769 MN m-2 for A. plurijuga. Based on its dynamic modules, the Woods of F. americana and A. plurijuga can be used in structural design. Instead, S. campanulata can be used as a component in products where high mechanical resistance is not required.
