Propriedades de chapas fabricadas com partículas de madeira de paricá (Schyzolobium amazonicum Huber ex. Ducke) e fibras de coco (Cocos nucifera L.)

摘要

This work had as its objective to determine the properties of particleboards fabricated with paricá particles (Schyzolobium amazonicum Huber ex. Ducke), with increasing proportions of coconut fibers (Coconuts nucifera L.). Boards were fabricated with 6 or 8% of urea-formaldehyde adhesive. Particleboard mean density was equal to 360 kg/m3. The addition of coconut fibers didn't affected boards' dimensional stability, higrospicidity, water absorption capability. However it increased its mechanical properties. The addition of 8% of adhesive improved all board properties.
