Tyre Compounding for Improved Performance
Rapra Review Report, Vol. 12, No. 8, Report 140, 2002
Dr. M. S. Evans, Kumho European Technical Centre

 Summary... |
|
This review gives an overview of the factors compounders and
engineers must consider when developing materials for tyres,
to meet the demanding performance requirements of the 21st Century.
It is an introduction to a complex subject, but will be of interest
to the tyre and automotive industries as it covers the latest
developments and future prospects for tyres and tyre compounds.
The review discusses various compounding ingredients, the measurement
of their properties and the ultimate measurement of tyre performance.
Also included are a large number of references to other published
articles.
Tyres comprise several different components, each with varying
formulations: the inner liner, the carcass, the bead, the apex,
the sidewall, the belt, the cap-ply and the tread. These are
described separately.
Tyre performance is measured in a number of different ways,
and the application of the tyre itself will influence the choice
of tests. The key performance properties for tyres have been
described as the 'magic triangle', i.e., rolling resistance,
wear and wet grip. The art of compounding is to balance out
all of these performance requirements for the tyre and to relate
the test results on built tyres to the rubber compounds and
processes used in production.
The future of tyres in vehicles is also outlined. There is potential
for tyres to become "smart" through the inclusion of sensors
to provide feedback about tyre and road conditions to vehicle
systems. In addition, most manufacturers now have products that
will run for a given distance even after air is lost.
Finally the environmental aspects for end of life tyres are
discussed.
