Effects of manufacturing parameters on mechanical properties of particleboards with the core layer made from willow Salix viminalis. Three-layer experimental particleboards were prepared using the willow Salix viminalis particles for the core layer and industrial pine particles for the face layers. The press temperature (180 and 200°C), press time (4 and 6 min) and shelling ratio (0.3 and 0.4) were variable parameters. The modulus of elasticity (МОЕ), modulus of rupture (MOR), internal bond (IB) and screw holding strength (SHS) of particleboards were investigated. In general, the considered factors significantly affected the mechanical properties of particleboards.
