Determination of the distribution of different filling materials in SBR matrix compounds by image processing

In this study, the distribution of walnut shell ash and cone ash, which were used in different proportions as the filling materials of SBR rubber compounds, in the matrix were investigated by the developed image processing program. Styrene-Butadiene Rubber (SBR 1502) was employed as the main matrix material. Adhering to the same compound in the experiments, in addition to the carbon black in the compound, 5 different and 10% by mass of Walnut Shell Ash (WSA) was added to the dough, and the Cone Ash (CA) by 5% and 10% by mass, creating a total of 5 different compounds. SEM images of the rupture surfaces were taken and transferred to the developed image processing program, in which the areas covered by walnut shell ash and cone ash in the images were determined. The number of designated surface areas and the area it covers on the image were removed.
