Özet
This study is part of a comprehensive study on the industrial production of reinforced laminated wood composites. The main aim of the study is to determine the production parameters of reinforced laminated wood composite board under an optimal production cycle time under temperature and pressure, using epoxy resin cured at room temperature for 24 h. For this purpose, 1.2 mm thick Samsun Poplar (Populus Deltoides I-77/51) veneer layers, three different pressing cycle times (15, 20, and 25 min), three different temperatures (100 degrees C, 120 degrees C, and 140 degrees C), and three different amounts of adhesive (100, 150, and 200 g/m(2)) were used also 200 g/m(2) density twill woven glass-carbon fiber fabric was used as the reinforcement layer. In order to determine the production quality of reinforced laminated wood composite boards, the adhesion strength between the reinforcement layer and the wood veneer layer was determined according to TS EN 3969 314-1. Considering the adhesion strengths in terms of production parameters, the best results were observed at 100 degrees C press temperature, 20 min press cycle time, 200 g/m(2) adhesive amount, and the use of glass fiber woven fabrics for reinforcement. Under these conditions, the best adhesion strength was found to be 4.17 N/mm(2). When the samples were examined, it was seen that almost all of the failures occurred as a result of the fracture in the wood layer. This indicates that sufficient adhesion can be achieved between the reinforcement layer and the wood layer.
