description | Laminated wood can potentially replace solid wood to make a less variable and more homogeneous engineered material. There is little information that compares, simultaneously and in the same species, the ultrasound speeds, and the dynamic modules in solid versus laminated wood. The objective of the investigation was to verify experimentally, in small specimens, if the characteristics of Pinus pseudostrobus laminated wood are like those of solid wood. For this, their densities were calculated, and ultrasound tests were performed in the radial, tangential and longitudinal directions. Also, the speeds and dynamic modules were determined. The results indicate that the density of laminated wood increases, compared to that of solid wood. Speeds and dynamic moduli decrease in radial and tangential directions; instead, they increase for the longitudinal direction. It was experimentally verified that the magnitudes of density, velocity and dynamic modulus in laminated wood are like those of solid wood of this species. The variability in the studied characteristics decreases as an effect of reconstituting solid wood. For the speeds and dynamic modules of solid wood, their anisotropy ratios show proportions similar to those reported in the literature, but the magnitudes are specific to each species. The research provides reference data and shows that the solid and laminated wood of P. pseudostrobus can be characterized with a non-destructive method. |

La madera laminada potencialmente puede sustituir a la madera sólida para elaborar un material de ingeniería menos variable y más homogéneo. Existe poca información que compare simultáneamente, y en una misma especie, las velocidades del ultrasonido y los módulos dinámicos en madera sólida versus laminada. El objetivo de la investigación fue verificar experimentalmente, en probetas de pequeñas dimensiones, si las características de la madera laminada de Pinus pseudostrobus son similares a las de la madera sólida. Para ello, se calcularon sus densidades y se realizaron pruebas de ultrasonido en las direcciones radial, tangencial y longitudinal. También, se determinaron las velocidades y los módulos dinámicos. Los resultados indican que la densidad de la madera laminada aumenta en comparación con la de la madera sólida. Las velocidades y los módulos dinámicos disminuyen en las direcciones radial y tangencial; en cambio, aumentan para la dirección longitudinal. Se verificó experimentalmente que las magnitudes de la densidad, la velocidad y el módulo dinámico en madera laminada son similares a las de madera sólida de esta especie. La variabilidad en las características estudiadas disminuye como efecto de reconstituir madera sólida. Para las velocidades y los módulos dinámicos de la madera sólida, sus relaciones de anisotropía muestran proporciones similares a las encontradas en la literatura, pero las magnitudes son particulares a cada especie. La investigación aporta datos de referencia y demuestra que la madera sólida y laminada, de P. pseudostrobus puede ser caracterizada con un método no destructivo.
