Abstract
Se realizaron tableros de fibras a partir de fique, sin aditivos sintéticos. Las astillas de fique fueron tratadas con vapor en un reactor discontinuo de 8 L. La pulpa seca, se llevó a una prensa hidráulica, donde se formaron tableros de 3 mm de espesor y con dimensiones de 15 cm de longitud por 5 cm de ancho. Se varió la severidad en el pre-tratamiento con un rango de 3,5 a 4, así como la temperatura de prensado, desde 137 a 180ºC; durante el prensado, la presión se mantuvo constante en un valor de 4,94 MPa. Se lograron tableros con densidades por encima de 1000 kg/m3, módulos de elasticidad mayor a 2000 MPa, módulos de rupturas mayores a 10 MPa. Boards were made from sisal fibers without synthetic additives. Fique chips were steamed in a batch reactor 8 L. Dry pulp, was a hydraulic press, where they formed panels 3 mm thickness and dimensions of 15 cm long by 5 cm wide. Severity was varied in the pretreatment with a range of 3,5 to 4, and the pressing temperature, from 137 to 180°C, during pressing, the pressure was kept constant at a value of 4,94MPa. Boards were achieved with densities above 1000 kg/m3 , moduli of elasticity greater than 2000 MPa, modules of rupture higher than 10MPa.
