Densification, Adhesive resistance, Reinforced wood


Wood material is the most critical indoor and outdoor building element that has not changed since ancient times. Previous studies have determined that the mechanical properties of tree species with low industrial importance, such as poplar wood, can be improved when they are subjected to the densification process. In addition, it has been determined in studies that the lamination process has a positive effect on the mechanical properties of the wood material. This study aimed to assess the impact of the glue type on the bonding strength during the lamination process of the densified black poplar (Populus nigra L.) using reinforcement material. Wood materials were subjected to densification at 140 °C for 10 min. Then, the densified boards were laminated in 3 layers with a reinforcement element (Kevlar®®, fiberglass, and carbon fiber) between the two wooden boards. It was determined that the best result was obtained with the combination of Akfix polyurethane resin type and carbon fiber reinforcement material (8.49 N/mm2).
