Abstract
Three mechanical tests with different loading modes were conducted to evaluate the effect of element type on the internal bond quality of woodbased panels In addition to the internal bond test which is commonly used for matformed panels interlaminar and edgewise shear tests were used to test oriented strandboard OSB particleboard mediumdensity fiberboard MDF of two thicknesses and plywood The following results were obtained Epoxy resin proved to be suitable for determining the interlaminar shear modulus instead of hotmelt glue There was a linear relation between panel density and interlaminar shear modulus and a linear correlation between the interlaminar shear strength and internal bond IB strength for the matformed panels tested OSB had the highest edgewise shear modulus and MDFs had the highest edgewise shear strength in this study The modulus/strength ratio also depended on both panel type and loading mode The relation between the shear moduli determined from the edgewise and interlaminar tests indicated the characteristics of the shear properties of panels made of different elements
