Characterization of the incorporation of a granular medium into elastomer matrices during mixing process

Mixing of filler particles with elastomers is one the most important steps in tire manufacturing process. Precipitated Silica (Si), as a filler, shows enhanced properties compared carbon black when incorporated an elastomer such low rolling resistance, high wet grip performance, and wear resistance. According to standard rubber mixing process, fragmentation during must yield breakage size that enables homogenous material. Hence, this experimental study concerned understanding behavior silica its incorporation elastomer. Incorporation done through shear forces present Internal Mixer. Different methodologies are used measure particle distribution. For free have been fragmented but not incorporated, we use Laser granulometry. embedded analyzed using X-ray tomography. The results obtained suggest follow erosion mechanism.
