Abstract

 

El objetivo de la investigación fue evaluar el densificado de ocho maderas mexicanas: 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, y Guazuma ulmifolia Lam. La madera se densificó con un proceso termo-mecánico. Antes y después del densificado, se determinaron experimentalmente, la densidad, la velocidad de onda por ultrasonido en la dirección longitudinal y el módulo dinámico. Además, se calcularon los índices de densificado, elástico y de calidad del tratamiento. Entre la madera no densificada y la madera densificada, en las ocho especies, se encontraron diferencias estadísticamente significativas para la densidad, la velocidad de onda y el módulo dinámico. Los índices de densificado, elástico y de calidad son similares a los mismos parámetros de las especies reportados en la bibliografía. Estos indicadores sugieren que es posible aumentar la densidad de estas especies y así ampliar sus usos.

Palabras claves: densidad; módulo dinámico; índice de densificado; índice elástico; índice de calidad.

Abstract

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.

Key words: density; dynamic modulus; density index; elastic index; quality index.
