AB  - The atomic force microscopy is method used to obtain surface properties of various materials, includ-ing surface morphology, local magnetization, conductivity and mechanical properties. In this work the atomic force microscope was used to investigate properties of rubber compounds. Three samples made of different rubber compounds that varied in filler content were studied in order to determinate their homogeneity and ratios of their Young's moduli. Images of their surface topography were ob-tained and then on each sample five places were chosen where spectroscopic curves representing force - distance dependence were scanned. Parts of these curves from which Young's modulus can be determined were approximated by linear functions and their slope was calculated. Slope values close to each other suggest similar values of Young's modulus. By their comparison it was determined whether even distribution of ingredients in rubber compound can be assumed and thus the blending process to produce these compounds can be considered sufficient.
