ABSTRACT

Adhesion and tribology studies performed on rubbers used for tires application have shown that they are submitted to mechanical loadings in two different frequency-temperature windows: (i) a first domain, so called “traction domain”, corresponds to what happens during car braking (from 104 to 107 Hz, temperature between 20 and 60°C); in this domain, energy dissipation is expected to be maximum; and (ii) a second domain at much lower frequency corresponds to the rolling resistance (from 10 to 100 Hz, temperature between 20 and 40 °C) where the energy dissipation increases the vehicle fuel consumption Figure 1.
