  • S0305-3-2 Effect of Carbon Black Fraction on the Fatigue Crack Growth Rate of Vulcanized Natural Rubber Used in Engine Mount Applications

抄録

The effect of carbon black loading on fatigue crack growth rate of vulcanized natural rubber used in automotive applications such as engine mounts was studied using pure shear specimens. Tearing energy was calculated from uncut specimens while crack growth rate was calculated from cyclic tests of cut specimens. Finally the fatigue crack growth rate as a function of tearing energy was determined. The fatigue crack growth rate of natural rubber at a given tearing energy was decreased with the increase in fraction of carbon black.
