This project is examining how the visco-elastic properties of different filled elastomer materials are affected by compounding and test temperature. Building on a relatively simple testing and modelling approach developed by a previous researcher in the group (Suphadon), this programme examines how the visco-elastic behaviour of a filled compound can be understood from a measure of the damping at small strains coupled with model creep experiments. The aim is to deduce the fundamental reinforcing mechanisms of filled elastomer materials.
