The effect of type of wood-based recyclate and low-quality timber in particleboard on mechanical properties of furniture joints

The effect of type of wood-based recyclate and low-quality timber in particleboard on mechanical properties of furniture joints / Viktória Satinová ... [et al.]. -- Fotogr., graf., sch., tab. -- Lit. - The effect of particleboard (PB) composition made of recycled or lower-quality timber on the mechanical properties of selected furniture joints is determined in the paper. The tested PBs were manufactured using recycled PB or blockboard from old furniture and lower- quality timber with brown or white rot. The laboratory-produced control PB with particle content of 100% sound spruce wood (Picea abies Karst. L.) and commercial PBs were used for comparison of the results. The load capacity and stiffness of corner joints with the confirmat (ø5 × 50 mm) and wooden dowel (ø6 × 30 mm) and the withdrawal resistance and stiffness of the screw (ø3.5 × 30 mm) were tested. The corner joints were loaded under compression by bending moment in the angular plane. In terms of load-carrying capacity, control PB was the most suitable in achieving a load-carrying capacity of 7827.61 N∙mm for the confirmat and PB from recycled blockboard 4072.71 N∙mm when using the wooden dowel. As for joint stiffness, the best values achieved were 1316.00 N∙mm/° and 808.58 N∙mm/° for the PB from recycled blockboard using the confirmat and dowel, respectively. PB from recycled blockboard again showed the highest values of screw withdrawal resistance - for the edge withdrawal 416.61 N and for the surface withdrawal 556.44 N. Considering the values found for the investigated mechanical properties, it was assumed that the tested materials can be used as non-load-bearing elements in furniture construction.
