Determination of the hygroexpansion properties of wood-based composite panels

Wood panels expand when exposed to moisture in service conditions. Consequently, their performance as an engineering material is impoverished and results in repair and/or replacement costs. The objective of the research was to determine the densities and hygroexpansions of plywood, strandboard, medi...

Consequently, their performance as an engineering material is impoverished and results in repair and/or replacement costs. The objective of the research was to determine the densities and hygroexpansions of plywood, strandboard, medium density and oriented strandboard. The same parameters were evaluated on a control group of Pinus pseudostrobus solid wood. Thirty-five randomly selected specimens were prepared from each material. Hygroscopy tests were performed with a protocol of humidification and drying of the experimental material. The hygroexpansions of plywood, strandboard, medium density and oriented strandboard are different compared to the hygroexpansion of P. pseudostrobus solid wood. Wood and wood-based panels exhibit hygroscopic character, which results in dimensional variation if their moisture content is changed. The magnitudes of the hygroexpansions of the four boards studied are greater than that of solid wood of P. pseudostrobus. Los tableros de madera se expanden cuando están expuestos a la humedad en condiciones de servicio. En consecuencia, su funcionamiento como material de ingeniería empobrece y ocasiona costos de reparación y/o remplazo. El objetivo de la investigación fue determinar las densidades y las higroexpansiones de tableros contrachapados, enlistonados, de densidad media y de astillas orientadas de madera. Se evaluaron los mismos parámetros en un grupo de control de madera sólida de Pinus pseudostrobus. De cada material se prepararon 35 probetas seleccionadas al azar. Se realizaron pruebas de higroscopía con un protocolo de humidificación y secado del material experimental. Las higroexpansiónes de los tableros contrachapados, enlistonados, de densidad media y de astillas orientadas son diferentes en comparación con la higroexpansión de la madera sólida de P. pseudostrobus. La madera y los tableros de madera presentan un carácter higroscópico, el cual resulta en una variación dimensional si su contenido de humedad se modifica. Las magnitudes de las higroexpansiones de los cuatro tableros estudiados son mayores a la correspondiente a la madera sólida de P. pseudostrobus.
