Fatigue Crack Growth Behavior of Carbon Black–reinforced Natural Rubber

Abstract: Fatigue crack growth behavior of carbon black–reinforced natural rubber is investigated. Rubber compounds of Shore A = 70 are prepared by varying the formulation loadings of a wide range of carbon black types based on their structure and surface area properties. The resulting fatigue crack growth behavior shows significant variation in β exponent values, depending on the properties of the carbon black. These variations are rationalized by considering the strain amplification of natural rubber by carbon black a… Show more

“…Therefore, the search for alternative materials and understanding their interaction with rubber is crucial to map the losses and completely replace carbon black, achieving new results in this field. To replace carbon black, the substitutes must have particles between 25 and 500 nm in size, as well as functional groups and a morphology suitable for interaction with the elastomer 5,6 .…”

“…In such instances, a small Payne Effect is desirable. For fracture applications, however, energy dissipation allows for the removal of energy from a propagating crack, thus improving the tear resistance of the elastomer [ 7 ]. In these cases, a larger Payne Effect would allow for higher levels of energy dissipation.…”

“…For this reason (among others), almost all technical goods are highly filled. An exemption may be strain-crystallizing polymers, most importantly natural rubber (NR) [1][2][3]. Nanoscopic carbon black was the first and is still the most-used reinforcing filler for rubbers.…”
