The Effect of Diameter and Prehole Clearance for Wooden Dowel on the Withdrawal Loads of Domestic Particleboard

Wooden dowels are commonly used to join the particleboard members together in many types of structures, But little information is available concerning their holding properties in domestic particleboard. This study was performed to determine the withdrawal loads and strengths on the effect of diameter of dowel and hole clearance. The test block was manufac-tured from 15 mm thick domestic particleboard. The dowel was manufactured 6, 8 and 10 mm diameters from korean castanea, korean pine and tuliptree. Research reported here indicates that withdrawal loads increase, but withdrawal strengths decrease, as the dowel diameter increases. This study also indicates that dowel withholding load and strength for particleboard less de-crease than those for domestic wood as a hole clearance decreases.
