Abstract
In this study surface characteristics of commercially manufactured overlaid medium density fibreboard (MDF) and particleboard panels were evaluated. Roughness was measured randomly from the surface of overlaid samples conditioned at 55 and 93 relative humidity (RH) levels using a fine stylus profilometer. Three roughness parameters namely average roughness (Ra) mean peak-to-valley height (Rz) and maximum roughness (Rmax) were used to determine surface profiles of samples. Statistical analysis revealed that no significant difference was found between roughness values of MDF and particleboard panels exposed to 55 RH. However when samples were exposed to 93 RH significant difference between initial and final roughness values was observed. Janka hardness values of samples exposed to 93 RH were significantly lower than those exposed to 55 RH. It appears that roughness of overlaid samples due to humidity exposures can be quantified using stylus type equipment and such data along with hardness characteristics may be used to improve overall quality of panels for further processes.
