Summary

Over the last 60 years, plastics have contributed significantly to the functioning of modern day society. In the foreseeable future, plastics will continue to expand their importance as essential materials in diverse fields as human health, agriculture, transport, packaging, and energy conservation. The increasing usage of plastics continuously poses new scientific and technological challenges ranging from designing new plastics to improved processing and better performance of finished goods. Understanding rheology of plastics is essential for tackling these challenges. In particular, plastics' processing is a key challenge to understand. For polymer melts this means developing accurate constitutive models that describe the flow of polymer melts in industrially relevant flow geometries. The availability of reliable constitutive models, associated material parameters and robust numerical analysis tools allows an early investigation of the final polymer melt performance and provide vital information to optimise the processing methods and/or the polymer composition. However, there exists neither a generally accepted method to extract the relevant rheological parameters from experimental data, nor a consensus on which is the most appropriate constitutive equation to use. Furthermore, there is a lack of critical assessment of the reliability of available simulation programs in model flow situations that are simply enough for rigorous experimental control. The Advanced Rheological Tool (ART) development project aims at meeting said challenges. This entails the extensive rheological characterisation of selected polymer melts, the detailed comparison of constitutive equations simulations to prototype industrial flow experiments, the improvement of existing constitutive equations, and the development of robust numerical methods for efficient polymer melt processing simulations. Consequently, the projects results can be used: to unambiguously compare and validate rheological models; to define a constitutive equation that given the state of the art will provide the most accurate flow simulations; and to assist in new polymer and processing equipment design using minimal amounts of materials and subsequently reduce development time.
