Densidad, módulos dinámicos longitudinales e índices de calidad resultantes del densificado de la madera de especies tropicales

Abstract

El aumento en la magnitud de una característica física de la madera, sin depreciar otras propiedades, se considera un avance tecnológico con posibles aplicaciones en ingeniería. Así, bajo la hipótesis de que el densificado de la madera aumenta su densidad y su módulo dinámico, la investigación tuvo como objetivos, por una parte, determinar estos parámetros, para comparar el comportamiento de la madera sólida frente a la madera densificada, y por otra, calcular a posteriori, los índices de densificado, elástico y de calidad. Se densificaron veinte probetas de las siguientes especies: Cupressus lusitanica, Cedrela odorata, Swietenia macrophylla, Tabebuia donnell-smithii, Fraxinus uhdei, Fagus grandifolia subsp. mexicana, Dalbergia palo-escrito y Guazuma ulmifolia. Tanto antes como después del tratamiento se realizaron pruebas de vibraciones longitudinales. Como resultado del densificado, las densidades de las maderas aumentaron en promedio 35% y los módulos dinámicos se incrementaron 46%. Los resultados de los índices de densificado, elásticos y de calidad sugieren que el tratamiento de densificado es eficaz para aumentar la densidad y el módulo dinámico de maderas con un amplio rango de densidades.
