Medium density fiberboard, oriented strandboard, particleboard, thickness swell, vertical density distribution


A procedure was developed to determine the thickness swell distribution of wood composite panels, based on the vertical density distributions from before and after the water soak test. The procedure used a linear relationship of the density between adjacent density data points in the vertical density distribution, and it assumed a constant weight of an individual horizontal layer after swell. A computer algorithm was developed for this estimation. The procedure was used to examine the thickness swell distribution of medium density fiberboard, oriented strandboard, and particleboard. Thickness swell distribution in relation to the layer density was discussed.
