Technical Abstract: Corn flour is an economical renewable material and investigated in this study as filler for rubber composites. The composites were prepared by mixing an aqueous dispersion of corn flour with rubber latex, followed by freeze-drying and compression molding. The small strain elastic modulus and the strain recovery behavior of corn flour filled rubber composites were measured and compared to those of carbon black, wheat starch, and wheat flour filled rubber composites. The reinforcement effect of corn flour in the composites was found to be significant and its composite moduli were higher than that of carbon black filled rubber composites. Compared to wheat flour filled composites, corn flour filled composites had a greater concentration-dependent modulus. Strain recovery and stress softening properties indicated that the corn flour filled composite with twenty percent filler was resilient and gave a good recovery behavior comparable to that of carbon black composites.
