| description | The aim of the research was to determine the density and the elasticity modulus of Guazuma ulmifolia, Spathodea campanulata and Abies religiosa wood and to observe the effect produced by a boron salts impregnation process on these properties. Thirty-five sets of standard specimens were studied, and impregnated with a 3% concentration solution with a hot-cold bath method. Before and after the treatment, transversal vibration tests were realized. Average values of density, natural frequency and elasticity modulus are proportional to Mexican woods previously reported. Quantitatively, results of boron salts retention were comparable with the ones reports in the bibliography. Considering that the three species were exposed to the same treatment of impregnation and tested with a non- destructive method, the research concluded that each wood species mechanically reacts in a different and independent way to the process of impregnation of Boron salts. |

Densidad Módulo de elasticidad Absorción Retención Baño caliente-frío Density elasticity modulus Absorption Retention Hot-cold bath The aim of the research was to determine the density and the elasticity modulus of Guazuma ulmifolia, Spathodea campanulata and Abies religiosa wood and to observe the effect produced by a boron salts impregnation process on these properties.

El objetivo de la investigación fue determinar la densidad y el módulo de elasticidad de madera de Guazuma ulmifolia, Spathodea campanulata y Abies religiosa y observar el efecto del proceso de impregnación con sales de boro sobre estas propiedades. Se estudiaron lotes de 35 probetas normalizadas y se impregnaron con una solución con una concentración del 3% con el método baño caliente-frío. Antes y después del tratamiento de impregnación se realizaron pruebas de vibraciones. Los valores promedio de la densidad, frecuencia natural y módulo de elasticidad son proporcionales a los reportados para maderas mexicanas. Cuantitativamente, los resultados de retención son comparables con los de la bibliografía. Considerando que las tres especies fueron sometidas al mismo tratamiento de impregnado y probadas con un método de carácter no destructivo, se concluye que cada especie de madera responde mecánicamente de manera diferente e independiente al proceso de impregnación con sales de boro.
