“…47 Internal friction dictates the degree of local segmental motion, and thus, is responsible for the bulk viscoelastic and relaxation properties of polymeric materials. Grosch 18 and Ludema and Tabor 48 were the first to combine the velocity at the friction peak with the frequency for the maximum viscoelastic loss to deduce a characteristic dissipative length scale. However, with their macroscopic techniques, they could only suspect dissipation through segmental relaxation.…”

“…Again, these early models neglected the inherent viscous attributes of elastomers. According to Savkoor 28 as well as Ludema and Tabor, 25 sliding may proceed by an activated process, but the extent to which the two surfaces come into contact depends on modulus and sliding velocity. Hidden in more macroscopic terms, these approaches of Savkoor 24 and Ludema and Tabor 25 are similar to the model of Schallamach,20 where the activated nature of the sliding process is still attributed to adhesive debonding.…”

We present an experimental investigation of the non stationary frictional properties of multicontact interfaces between rough elastomers and rough hard glass at low velocities (≤ 200 µm s −1 ). These systems, for which the deformation contribution to friction is negligible, are shown to exhibit a phenomenology which is similar to what is observed for non elastomeric materials in the same multi-contact configuration, and which are quantitatively described by the state-and rate-dependent friction laws. This permits to identify clearly the two contributions to adhesive friction which are mixed in steady sliding : the interfacial shear stress which appears as thermally activated formation and breaking of molecular bonds, and the real area of contact which evolves through viscoelastic creep of the load bearing asperities.

“…[1][2][3] Moreover, it is said that the friction frequency are the high frequency band(10 2~1 0 6 Hz). However, a general viscoelasticity evaluation method DMA (Dynamic Mechanical Analysis) is limited in the low frequency(10 1~1 0 2 Hz)measurement.…”

Viscoelasticity evaluation of rubber by surface reflection of supersonic wave

The main characteristic of rubber is a viscoelasticity. So it is important to research the characteristic of the viscoelasticity of the high frequency band for the friction between a rubber material and the hard one with roughness, for instance, the tire and the road. As for the measurement of the viscoelasticity of rubber, DMA (Dynamic Mechanical Analysis) is general. However, some problems are pointed out to the measurement of the high frequency band by DMA. Then, we evaluated the viscoelasticity characteristic by the supersonic wave measurement. However, attenuation of rubber is large, and when the viscoelasticity is measured by the supersonic wave therefore, it is inconvenient and limited in a past method by means of bottom reflection. In this report, we tried the viscoelasticity evaluation by the method of using complex surface reflection coefficient and we compared with the friction coefficient under wide range friction velocity. As a result, some relationships had been found for two properties.We report the result that character of viscoelasticity of rubber was comparable to friction coefficient.
