Soybean has become one of the major food resources nowadays. Increased cultivation results in large amount of side products, such as soybean hulls and stems which can be used for variety of purposes. By using pyrolysis processes which thermally decompose the material in an inert environment, soybean hulls are converted into the carbon-rich black fillers. This research investigates the effectiveness of pyrolyzed soybean hulls (PSBH) as an alternative eco-friendly reinforcement filler to replace carbon black (CB) in natural rubber compounds. For this purpose, carbon black was replaced by four types of PSBH with weight percent varying from 0% to 35%. Ball milling of PSBH was performed to investigate the effect of size reduction on the mechanical properties of natural rubber compounds. Among two types of PSBH pyrolyzed at 450℃ (A) and at 500℃ (B), ball milled PSBH B filled natural rubber vulcanizates obtained the higher tensile strength values, but the values were still inferior to the pure CB filled counterparts. Bound rubber measurement and swelling experiments were carried out to evaluate the interaction between fillers and rubber polymer chains. Using dynamic mechanical analysis (DMA), it was determined that addition of PSBH into rubber compounds resulted in lower wet-skid resistance while improving the rolling resistance.
