Selected properties of the structural particleboards produced with use of Hazel (Corylus avellana L.) wood particles

This study investigated the potential of hazelnut wood (Corylus avellana L.) as an alternative raw material in the production of single-layer structural particleboards. Boards with a target density of 700 kg·m⁻³ and thickness of 13 mm were manufactured using varying substitution levels (5%, 10%, 25%, 50%, and 100%) of hazel wood particles relative to industrial pine (Pinus sylvestris L.) particles. Phenol–formaldehyde (PF) resin was used as the adhesive at a 15% resination rate. Mechanical and physical properties, including modulus of rupture (MOR), modulus of elasticity (MOE), internal bond (IB), screw withdrawal resistance (SWR), water absorption (WA), and thickness swelling (TS), were evaluated according to relevant European standards. Density profiles (DP) were also assessed.
