Determination of diagonal compression and tension performances for case furniture corner joints constructed with wood biscuits

This study was carried out to determine the performance of different wood biscuits on the diagonal compression and tension strength for case-type furniture corner joints. For this purpose, melamine-coated particleboard (MCP) and melamine-coated fiberboard (MCF) panels were bonded with polyvinyl acetate (PVAc) and Desmodur VTKA (DVTKA) adhesives on miter joint (Mj) and butt joints (Bj). The diagonal compression and tension strength tests were done according to ASTM D 1037 standards. As a result, the highest diagonal compression and tension strength were obtained in MCF with DVTKA adhesive, As for the interactions, panel + adhesive + corner joints, the highest value was MCF + DVTKA + miter joint in both compression and tension tests. According to these, it is advised that the member of the wood biscuits produced from solid woods is used in the corner joints in case furniture.
