Simulation and Analysis of Surface Roughness of Soft Polymeric Materials by Fractals
Keywords:abrasion, surface roughness, correlation function, fractal dimension.
The surface roughness is important design factor for the adhesive bonds. Thus, in this work we have investigated the profiles of roughened surface of soft polymeric material. Five different grades of abrasive paper were used to produce different degrees of roughness on the monolithic butadiene-styrene rubber surface. The fractal model of surface roughness was proposed. It was determined that fractal dimension of profiles of roughened surface depends on grade of abrasive paper. It was shown that fractal dimension can be used to characterize the roughness of rubber surface.
