Dynamic moduli of filled elastomers – A coarse grained computer model

A coarse grained computer model is presented in the context of dynamic mechanical analysis of filled elastomer networks. The model relates both storage and loss modulus as functions of shear frequency and strain amplitude to filler content and structure as well as to parameters describing matrix–filler and filler–filler interaction on the nano-scale. We show how such a coarse grained model may be used to guide the developer of filled elastomer applications in the understanding of the interplay between molecular interface design and macroscopic performance with respect to the Payne effect.
