Non-linear Viscoelastic Behaviour
of Rubber-Rubber Blend Composites
and Nanocomposites: Effect of Spherical,
Layered and Tubular Fillers
Ajalesh B. Nair, Neena George, and Rani Joseph
Abstract This chapter deals with the non-linear viscoelastic behaviour of rubberrubber blend composites and nanocomposites with fillers of different particle size.
The dynamic viscoelastic behaviour of the composites has been discussed with
reference to the filler geometry, distribution, size and loading. The filler characteristics such as particle size, geometry, specific surface area and the surface structural
features are found to be the key parameters influencing the Payne effect. Non-linear
decrease of storage modulus with increasing strain has been observed for the
unfilled vulcanizates. The addition of spherical or near-spherical filler particles
always increase the level of both the linear and the non-linear viscoelastic properties. However, the addition of high-aspect-ratio, fiber-like fillers increase the
elasticity as well as the viscosity.
