Evaluation of Mechanical and Physical Properties of Particleboards with the Core Layer Made from Willow (Salix viminalis)

Abstract


The objective of this study was to investigate some mechanical and physical properties of three-layer particleboards with the core layer made from various willow (Salix viminalis) and industrial pine wood particle mixtures. Increasing willow content slightly worsened the modulus of elasticity and modulus of rupture but improved internal bond, screw holding, water absorption, and thickness swelling. The effects of resin content in the core layer and the density of particleboards were also studied. Mechanical properties, especially modulus of elasticity and internal bond, of particleboards with willow particles met the requirements of EN 312 standard for boards of type P2. The willow (Salix viminalis) can be considered as a substitute for pine wood for the manufacturing of the core layer of three-layer particleboards.
