Abstract
This study outlines a novel method to evaluate friction and wear performance in tire tread compounds. This new laboratory method takes into account the realistic contact force of a tread block impacting the road during each revolution of the tire. The dynamic contact between the sample and the abrader is simulated in a manner which more closely replicates a real tire's contact behaviour. The contact period accounts for the correct timing and the contact pressure that is typical for a passenger car driving under low-speed conditions. Two styrene-butadiene rubber (SBR) tyre tread compounds each filled with the same volume fraction of carbon black were vulcanized and abraded under this loading sequence. An analysis of the friction and the evolution of wear morphology are described in detail to provide insight into the governing mechanisms that determine tire tread performance.
期刊介绍：
Polymer Testing focuses on the testing, analysis and characterization of polymer materials, including both synthetic and natural or biobased polymers. Novel testing methods and the testing of novel polymeric materials in bulk, solution and dispersion is covered. In addition, we welcome the submission of the testing of polymeric materials for a wide range of applications and industrial products as well as nanoscale characterization.
The scope includes but is not limited to the following main topics:
Novel testing methods and Chemical analysis
• mechanical, thermal, electrical, chemical, imaging, spectroscopy, scattering and rheology
Physical properties and behaviour of novel polymer systems
• nanoscale properties, morphology, transport properties
Degradation and recycling of polymeric materials when combined with novel testing or characterization methods
• degradation, biodegradation, ageing and fire retardancy
Modelling and Simulation work will be only considered when it is linked to new or previously published experimental results.
