Surface roughness analysis of wood composites: a stylus method

The surface roughness of hardboard and medium density fiberboard (MDF) were measured with a fine stylus technique. These composite samples were evaluated for surface roughness as well as surface stability after exposure to one relative humidity cycle. Three surface roughness parameters, average roughness, mean peak-to-valley height, and maximum individual peak-to-valley height obtained from 15 board surfaces were used for the analysis. It was found that board density had an effect on surface smoothness of hardboard samples. Hardboard also showed better surface stability compared to MDF. Visual inspection of scanning electron microscope photographs taken of the board surfaces did not show a direct relationship to quantitative surface roughness values obtained from the stylus technique.
