Design of Experiments for Green Tire Tread Compound Development by Reducing Conventional Carbon with an Eco-Friendly Filler

Abstract:

Several parameters are required to improve Tire dynamic performances like high wet and dry traction (Grip), high wear resistance and high steering performance (handling). These performances depend on the physical properties of tire tread compound, tire construction, tread profile and road conditions. The most influential one is the reinforcing filler, which is responsible for inheriting the tread dynamic properties. Conventionally, carbon black is used as filler but it possesses a major hitch of CO₂ emission during manufacturing as well as in service conditions. Its high rolling resistance is responsible for boosting the carbon footprint of a vehicle. In the past few decades, the focus has been shifting on silica fillers, an emerging technology to develop low rolling resistance tires resulting in low CO₂ emissions thus contributing in the establishment of a healthy eco system. Design of Experiment (DOE) approach is used therefore, sixteen (16) variants of silica based compounds were prepared and properties of silica based samples were compared with that of carbon black compounds (conventional). The results revealed that this emerging silica filler showed promising results in giving the highest possible wet traction and lowest rolling resistance to minimize CO₂ (Greenhouse gas) in the environment.
