Bamboo-oriented strand board (BOSB) with superior physical properties can be used in the furniture industry to alleviate wood shortages. Two types of plug-in connectors were designed in this paper: a splint-type connector and V-type connector. By cantilever bending, corner tension, and compression tests of L-type corner joints of BOSB and wood-oriented strand board (WOSB), the connection performance of the new connectors and six typical connectors was compared. The new connectors function like clamps, do not require that a screw or bolt pass into or through the board, and can be assembled repeatedly. The V-type connectors were more suitable for BOSB, and the joints exhibited the highest ultimate bending moment values (133.9 N·m, 86.8 N·m, 117.7 N·m). The splint connectors were more suitable for WOSB and their ultimate bending moment values (57.1 N·m, 45.3 N·m, 61.3 N·m) were greater than the joints fixed by V-type connectors (50.4 N·m, 35.4 N·m, 46.1 N·m). The results revealed that the connector performance affects the joint strength and that different plates were suitable for different connectors. A joint failure analysis revealed two simple failure modes for the two new connectors.

In this study, the aim was to optimize the cross-sectional geometry of auxetic dowels for furniture joints. For this purpose, two different sizes of auxetic dowels were chosen, one for frame- and the other for panel-type furniture joints for designing the cross-sectional geometry. Auxetic patterns that are created on the cross-sectional area cause deficiency of the materials, and this phenomenon decreases the modulus of elasticity (MOE) and increases the member stress. Accordingly, maximum MOE values and minimum Poisson’s ratio levels were determined for the optimum strength-auxetic behavior relation by means of a Monte Carlo method. Furthermore, Poisson’s ratio of the optimized dowel’s cross-section was confirmed with experimental tests, numerical analyses and analytical calculations. As a result, Poisson’s ratio values were obtained as negative values and confirmed, which means the dowels designed in this study had auxetic behavior. In conclusion, it could be said that studies should be conducted on the performance of auxetic dowels in both frame and panel furniture joints.

“…The popularity of furniture in flat packages RTA, however, forces a new need to expand their availability among the elderly, disabled, or those who do not have the technical ability to assemble with tools. For this reason, new fasteners are created with an original design and method of operation [ 25 , 31 , 32 ]. New joints are externally invisible, quickly mounted, and dismounted without tools.…”

“…New joints are externally invisible, quickly mounted, and dismounted without tools. Common tests of this type are computer simulations using the finite element method (FEM) [ 25 , 31 , 33 , 34 , 35 ]. From a cognitive and practical point of view, it would also be interesting to determine the impact of the mechanical properties of wood-based materials on the mounting forces and stiffness of newly designed joints for RTA furniture.…”

This study aimed to numerically and experimentally analyze the effects of internal mounting forces and selected materials on the stiffness and bending moment capacity of L-type corner joints connected with novelty-designed 3D printed fasteners. The experiments were carried out using medium-density fiberboard, high-density fiberboard, beech plywood, particleboard, and beech (Fagus silvatica L.) wood. The results showed that the joints made of beech wood were characterized by the largest bending moment capacity (12.34 Nm), while the worst properties were shown by particleboard (2.18 Nm). The highest stiffness was demonstrated by plywood joints (6.56 kNm/rad), and the lowest by particleboard (0.42 kNm/rad). Experimental studies have reasonably verified the results of numerical calculations. The test results confirmed that the geometry of new fasteners promotes the mounting forces under the assembly of the joints. It was shown that the higher the density of the materials, the greater the value of the mounting forces (164 N–189 N).
