Viscoelastic Response and Adhesion Properties of Highly Filled Elastomers

Abstract

The viscoelastic response of four highly-filled elastomers has been investigated. Small deformation dynamic testing of these materials reveals that they are nonlinear viscoelastic, as well as thermorheologically complex. Nonlinear viscoelastic behavior was observed as a pronounced strain dependence in the range of 0.1 to 10%. The degree of this nonlinear response was quantified through a constitutive equation containing a single nonlinear factor; resultant nonlinear factors for the various materials were compared and evaluated. Thermorheologically complex behavior was displayed by slightly different shift coefficients to superpose G' and G' data. An approach for calculating material resilience from the viscoelastic data was also developed and a nomographic technique presented for its application.
