In this study, three-layer particleboards are produced from a mixture of sunflower stalks (Helianthus annuus L.) and poplar wood (Populus alba L.) at certain ratios utilizing urea-formaldehyde (UF) adhesives. Panels with a density of 0.7g/cm(3) are manufactured with the ratios of 25, 50, and 75 percent particles from sunflower stalks or poplar. For comparison, panels are solely manufactured with sunflower stalks and poplar wood.
