Session A - Room #18 (The International Exposition (I-X) Center)
Robert H. Schuster, Dik, Deutsches Institut für Kautschuktechnologie, Hannover, Germany and Marion Schellenberg, German Institute of Rubber Technology (DIK), Hannover, Germany
The main focus of the contribution concerns with the phenomenon of the strain amplitude dependency of the storage modulus (“Payne-Effect”) of the rubber/layered silicate nanocomposites. It will be shown that especially the degree of exfoliation increases the storage modulus at constant filler volume fraction, whereas the orientation of the platelets in shear and elongational flow tend to reduce the Payne effect. The influence of process parameters and experimental conditions will be discussed.
