AI Insight
This study investigates the mechanical and performance properties of natural rubber (NR) and styrene-butadiene rubber (SBR) blends when reinforced with various grades of carbon black fillers for tire tread applications. The research compares how different carbon black particle sizes and surface areas affect key properties including tensile strength, abrasion resistance, and dynamic mechanical behavior. Results show that higher structure carbon blacks provide superior reinforcement, with optimal NR/SBR blend ratios and specific carbon black grades identified for balancing wear resistance and rolling resistance in tire treads.
Why it matters
These findings enable tire manufacturers to optimize rubber formulations for improved fuel efficiency and tire longevity by selecting appropriate carbon black reinforcements and blend compositions. The research contributes to developing more sustainable tire materials that reduce environmental impact through extended tire life and lower vehicle fuel consumption.
