Abstract

The objective of the research was to determine the electrical resistivity of the wood of Pinus pseudostrobus, Tabebuia rosea and Quercus scytophylla in the directions of anisotropy. For this, 20 solid wood specimens of each of the species with dimensions of 20 mm × 20 mm × 20 mm in the radial, tangential and longitudinal directions, respectively, were prepared, and the density and moisture content of the wood were determined. wood. To carry out the electrical resistivity tests, the electrical resistance was measured using direct current with a test voltage of 1000 volts. Moisture content was for P. pseudostrobus 12,6 %, for T. rosea 10,6 % and for Q. scytophylla 15,6 %. The average transverse electrical resistivity was for P. pseudostrobus 45,5 MΩ m, for T. rosea 10,3 MΩ m and for Q. scytophylla 61,4 MΩ m. The longitudinal electrical resistivity was for P. pseudostrobus 24,7 MΩ m, for T. rosea 2,.2 MΩ m and for Q. scytophylla 19,6 MΩ m. The magnitudes of the longitudinal resistances measured in the three woods are similar to those of the woods reported in the literature. Another finding was that the resistivity values show differences between the anisotropy directions of the wood and between the species studied.
