Dynamic Properties of Rubber Blends (NR/BR.cis) Under the Effect of Different Blending Ratio and Carbon Black Type

Due to the wide use of rubber components in different engineering applications such as vibration isolators, engine mounts, car tires, and bridge bearing pads, etc. This component mostly subjected high levels noise which are among most reasons that lead failure structures. In present paper has been performed experimentally investigate influences: content ratios natural (NR) polybutadiene (BR.cis) blends [1: (50/50) %, 2: (60/40) 3: (70/30) 4: (80/20) 5: (90/10) 6: (100/0) % pphr], two carbon blacks types (N375, N220) on dynamic properties (Rebound Resilience, Damping Time, Decay Rate). The experimental results showed compound blending ratio %] resilience (low damping), damping time displacement for black used this work. While these were improved whenever blend close percentage [5: %]. time, amplitude, a with (N220) decreased by (24.53 36.854 36.852 %), respectively, compared %.
