In this study, Black Locust (Robinia pseudoacacia L.) one of the fast-growing trees in Black Sea Region of Turkey was investigated for m anufacturing particleboard. The other purpose of this study was to determine if juvenile and mature woods adversely affects the thickness swelling (TS), water absorption (W A), static bending (SB) and internal bond (IB) strength properties of particleboards. Particleboards made from juvenile wood had lower static bending, internal bond, water absorption and thickness swelling values than those o f board made from mature wood. Results shovved that particleboard produced at 0,70 g cm'3 density had the requirements of IB and SB according to the EN standards. However, WA and TS values were higher than the required levels of the Standard. The hydrophobic substance was not used in the production of particleboard. For this reason, additiona! work is needed to im prove the physical properties of particleboard produced from Black Locust (Robinia pseudoacacia L.).
