The effects of wooden dowel species and the end distance of miniflex fasteners on the shear strength capacity of H-Type furniture joints
Abstract
Effects of the wooden dowel species and edge distances were studied relative to the shear force capacities of H-type furniture joints with minifix fastener under loadings. Melamine coated medium density fiberboard (MDF-Lam), minifix fasteners, and wooden dowels were used for specimen as used in the furniture industry. H-type joint specimens were tested in shear force. This compression tests were applied on 60 pieces of test samples prepared for this study based on the principles of ASTM D 1037-06 (2010). According to the results, the highest shear force capacities were obtained for beech dowel. According to edge distances from end distances, the highest shear force capacities were obtained with 72 mm distance from the edge. In manufacturing of wood composite based H type furniture, the highest shear force capacity values were obtained with the edge distance of 72 mm with oak dowel combination (1649 N), while the edge distance of 90 mm with beech dowel combination (1405 N) gave the lowest shear force capacity values. Furthermore, it was concluded that oak dowel as a substance and the distance 72 mm from the edge as distance could be recommended.
