In this study, to evaluate the effect of type and content of inorganic fillers on wear behavior, styrene-butadiene-rubber(SBR) compounds were prepared with 5 types of silica and 2 types of clay. In the case of Silica/SBR compounds, according to the particle size and structure of silica, wear behavior was investigated by using a blade-type abrader and Akron abrader. The compensated characteristic parameter(Ψc), which was the contributory factors of the combined effect of the particle size and filler structure, was introduced. This parameter was found to show a linear relationship with the Young's modulus. The Young's modulus correlated more with Ψc than the uncompensated characteristic parameter(Ψ). The wear resistance measured by a blade-type abrader and Akron abrader were inversely proportional to Ψc. The wear resistance of Silica/SBR compound is improved as smaller particle size and higher structure development of silica. Therefore, the structure development affects the wear behavior of Silica/SBR compounds more than the particle size of silica. The coefficient of determination(R2) of a linear relationship between Ψc and wear rate measured using a blade-type abrader was higher than those between Ψc and volume loss measured using Akron abrader for Silica/SBR compound. Thus, the blade-type abrader can be evaluate the effect of particle size and structure of silica on the wear behavior of SBR compound more accurately.In the case of Silica/Clay/SBR compounds, according to the types and contents of clay, wear behavior was investigated by using a blade-type abrader. For clay, Na-Montmorillonite(Na-MMT) and Organo modified Montmorillonite(OMMT) were used. The total contents of the reinforcing fillers were fixed at 50 phr, where clay content was varied from 1 to 3 phr. The wear rate and friction energy of the Silica/Clay/SBR compounds showed a good power-law relationship. The wear resistance of Silica/Clay/SBR compounds were decreased with increase content. However, in case of OMMT, the wear resistance were increased, as the content increased.
