Effect of adhesive type and glue-line thickness on the fatigue strength of mortise and tenon furniture jointsEinfluss von Klebstofftyp und Klebstofffugendicke auf die Festigkeit von Zapfenverbindungen in Möbeln

The fatigue strength of rectangular mortise and tenon rubberwood furniture joints made from polyvinyl-acetate (PVAc) and urea-formaldehyde (UF) adhesives were compared. The results showed that the allowable design stress for PVAc adhesive joints could be set at 30 % of its ultimate bending moment as compared to 25 % for the UF adhesive joint. Further, PVAc adhesive joints have large working tolerances for glue-line thicknesses which make it suitable for mass production furniture manufacturing.
