The objective of the research was to evaluate the densification of eight Mexican woods: Cupressus lindleyi Klotzsch ex Endl., Cedrela odorata L., Swietenia macrophylla King, Tabebuia donnell-smithii Rose, Fraxinus uhdei (Wenz.) Lingelsh, Fagus mexicana Martínez, Dalbergia palo-escrito Rzed. & Guridi-Gómez, and Guazuma ulmifolia Lam. The wood was densified with a thermo-mechanical process. Before and after densification, the density, the ultrasonic wave speed in the longitudinal direction and the dynamic module were determined experimentally. In addition, the densified, elastic and treatment quality indices were calculated. Between the non-densified wood and the densified wood, in the eight species, statistically significant differences were found for density, wave velocity and dynamic modulus. The densified, elastic and quality indices are similar to the same parameters of the species reported in the literature. These indicators suggest that it is possible to increase the density of these species and thus expand their uses.

Palabras clave : density; dynamic modulus; density index; elastic index; quality index.
