| Abstract: | The aim of this work is to analyse the influence of both silica content and the presence of a silane coupling agent on the viscoelastic behaviour of silica filled rubber. It is well-known that changes in the dynamic mechanical properties of filled rubber could result from either the mechanical coupling between phases and/or interface effects. Micro mechanical modelling, taking morphological analysis into account, will be used to separate these two effects and allows us to assess the actual properties of the polymer close to the silica surface. |
