Technical Abstract: Carbon black, a byproduct of the petroleum industry, is the world's most predominant filler for rubber composites. In this study, charcoal in the form of pyrolyzed agricultural products was evaluated as potential carbon-based filler for rubber composites made with carboxylated styrene-butadiene latex. This source of carbon is not dependent on the petroleum industry and (for two of the three samples) is a waste byproduct of a renewable biofuel process. Charcoal samples were ball milled, resulting in particle sizes of roughly 1 micron (based on number distribution; approximately 3-12 microns based on volume distribution). Composites were created using a method consisting of freeze-drying followed by compression molding to form bars that were tested rheologically. Charcoal filled composites showed reinforcement factors of up to 50 times greater than the unfilled latex.
