Silica is a reinforcing filler which is known for its ability to improve wet/snow grip and rolling resistance in tyres. However, incorporating Silica in high quantities impairs other significant features like physical properties and processing behaviour of the compounds. In this study, the focus was on balancing rolling resistance and grip properties while attempting to nullify the negative effects of Silica, by arriving at an optimum ratio of combination of Carbon Black and Silica. Three different compounds were prepared – COMP_1 had CB:Silica in 2:1 ratio, whereas COMP_2 and COMP_3 had CB:Silica in the ratios 1:1 and 1:2 respectively. The impact of their dosage on various properties were investigated. Taking into consideration abrasion loss and grip properties, 1:1 ratio was deemed to possess the optimized ratio.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
