Abstract

This study evaluated the mechanical properties of styrene-butadiene rubber/nitrile butadiene rubber (1:1) blends reinforced with carbon nanotubes at 0–15 phr. Tests included resilience, tear resistance, abrasion resistance, hardness, tensile strength, and elongation per ASTM standards. At 10 phr carbon nanotubes, the blend showed a tensile strength of 27.77 kgf/cm², elongation at break of 288%, and rebound resilience of 60.39% outperforming other ratios. Above 10 phr, performance plateaued or declined, suggesting an optimal loading limit. The 10 phr composition is suitable for high-strength, high-toughness applications in automotive and industrial sectors.
