Abstract :Wood plastic composites insert ignore into journalissuearticles values(WPCs); were produced from different mixtures insert ignore into journalissuearticles values(up to 45% by weight); of poplar insert ignore into journalissuearticles values(Populus alba L.); and pruning branches of black locust insert ignore into journalissuearticles values(Robinia pseudoacacia); wood flours, polypropylene insert ignore into journalissuearticles values(53 wt.%);, and maleic anhydride-grafted polypropylene insert ignore into journalissuearticles values(2 wt.%);. Weight loss, flexural strength insert ignore into journalissuearticles values(MOR);, flexural modulus insert ignore into journalissuearticles values(MOE);, notched impact strength insert ignore into journalissuearticles values(IS);, water absorption insert ignore into journalissuearticles values(WA);, and thickness swelling insert ignore into journalissuearticles values(TS); of WPCs after 24 h of immersion in distilled water were determined before and after incubation with white-rot fungus insert ignore into journalissuearticles values(Trametes versicolor); for 7 weeks. The MOR and MOE increased with an increase in poplar wood in the WPC. The notched IS decreased with an increase in black locust wood and poplar wood in the WPC. The weight loss in WPCs exposed to white-rot fungus was minimal for WPCs with a high amount of black locust pruning branch flour. The MOR and MOE declined after incubation with fungus. Fungal decay had a significant influence on the notched IS. Furthermore, the results indicated that the WA and TS of white-rotted WPCs for all the WPC formulations were significantly higher than those of unrotted WPCs.
