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 manufactured 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 decrease than those for domestic wood as a hole clearance decreases.

Wooden dowels are commonly used to join the wooden members together in many types of structures, But little information is available concerning their holding properties in domestic wood. 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 manufactured from 15 mm thick korean red pine and korean pine. 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, in a linear fashion as the dowel diameter increases. This study also indicates that dowel withholding load and strength increase in a linear fashion as a hole clearance decreases.

This study was performed to determine the withdrawal loads and strengths on the effect of dried wooden dowel. The test block was manufactured from 15 mm thick domestic wood and particleboard. Dowels of 6, 8 and 10 mm in diameter are made of korean castanea, korean pine and tulip wood. Research reported here indicates that withdrawal loads increase, but withdrawal strengths decrease, as the dowel diameter increases. This study also indicates that withdrawal load and strength of dried wooden dowel showed over 10% increase compared to those of normal conditioned dowel. However, there was an exception for the case of korean pine test block with dried tulip wood dowel. Meanwhile, the dried wooden dowel withdrawal loads and strengths for particleboard test blocks show 6~14.4% and 6.2~18.2% increase, compared to those of normal conditioned dowel, respectively.

Traditional complex joints have used to a wide variety of wooden furniture construction. Dowel joint is the most popular joint s. However design of this joint to meet specified service condition has been hampered by a lack of proven design formulas which can be use to predict their strength. The object of this study is to investigate the withdrawal strength and effect of dowel diameters in wood and wood based materials. The obtained results were as follows; 1. The relationship between withdrawal strength and dowel diameter is found to be linear. 2. Withdrawal strength of medium density fiberboard and Sepetir in end-to-side joints is superior to Antiaris, particleboard and plywood. 3. In end-to-end joints, withdrawal strength of medium density fiberboard is the most superior joint. but Sepetir. Antiaris and plywood have similarly strength and particleboard is inferiority. 4. Withdrawal strength in end-to-end joints of Antiaris and plywood is higher than in end-ta-side joints. But in end-to-end joints of Sepetir. medium density fiberboard and particleboard is similarity in end-to-side joints.
