Description: Repair of damaged pallets with metal connector plates (MCPs or plates) may reduce woodwaste while providing high quality, economical pallets. This study evaluated some effects of MCP repair on the performance of pallet components and some provisions of a preliminary standard for MCP repair of pallets. Whole pallet stringers and notched segments of stringers were tested in static bending; end feet were tested for resistance to fork tine impact. After repair at notch corners, stringers had greater strength but less stiffness than originally. MCP repair of above-notch failures could not restore the original strength or stiffness of notched segments. However, these repairs may be satisfactory in stringers, since only half the original above-notch strength is needed before the average stringer will fail between the notches. No differences were found in performance of different plate styles used to repair stringers and notched segments. Practical differences in the performance of these plate styles may exist under industrial conditions or with species other than oak. repaired end feet had greater impact resistance than originally. Wood species, rather than stringer width, had a greater influence on MCP repair performance for all components. Component testing may be a practical means of assessing the effect of repair techniques on pallet performance.
