A Study of the Combined Use of Carbon Black and Silicon Dioxide in Tyre Tread Formulations. Part 1. Processing and Vulcanisation Properties

A Study of the Combined Use of Carbon Black and Silicon Dioxide in Tyre Tread Formulations. Part 2. Static and Dynamic Properties of Vulcanisates

“…In communication 1 [1] we showed the influence of the content of carbon black and silicon dioxide on the processing and vulcanisation properties of a tread rubber mix. To explain the sharp change in a number of properties as a function of the carbon black/silicon dioxide ratio, an assumption was made concerning the considerable rearrangement of the physical structure of the rubber mix.…”

“…The aim of this work was to study the influence of the carbon black/silicon dioxide ratio on the static and dynamic properties of tread rubber. Figures 1 and 2 give the dependences of the main physicomechanical properties of rubber compounds, the compositions of which were described in communication 1 [1], on the carbon black/silicon dioxide ratio.…”

A Study of the Combined Use of Carbon Black and Silicon Dioxide in Tyre Tread Formulations. Part 5. the Payne Effect

“…In the previous communications [1][2][3][4], the results were given of studying the dependence of the processing, physicomechanical, dynamic, and service properties of tread rubbers on the content and ratio of silicon dioxide and carbon black in their composition. A ternary combination of rubbers was used as the rubber component: natural rubber of grade STR-20 (8.0 parts), stereoregular butadiene rubber SKD-N (20.0 parts), and oil-extended styrene butadiene rubber Buna VSL 4526-2 HM (99.0 parts).…”

A Study of the Combined Use of Carbon Black and Silicon Dioxide in Tyre Tread Formulations. Part 4. Tread Grip Capacity on Ice

“…In the present communication, the results are given of an investigation of the grip capacity of radial-car-tyre tread rubbers with different ratios of carbon black and silicon dioxide on an icy surface having a temperature ranging from −5 to −25°C. The composition of the rubbers was described in communication 1 [2]. Investigations were conducted on LAT 100 testing equipment (VMI) in a range of loads on the specimens of 5-150 N, and the speed of rolling on ice was 0.1-2.0 km/h.…”
