Technical Abstract: The current push for corn-based ethanol is creating a large surplus of affordable by-products that can potentially serve as filler material for rubber composites. Biomaterial fillers can help replace carbon black and reduce dependence on petroleum. This research examines the reinforcement behavior of various ethanol dry milling byproducts after undergoing pyrolysis to increase the carbon content. Ethanol byproducts were pyrolyzed and ground with a planetary ball mill, then blended with carboxylated styrene-butadiene, freeze-dried, and compression molded. The rubber composites were then rheologically tested to determine their reinforcement properties.
