Purpose and goal
In the project, experimental methodology and numerical models for fiber-based packaging materials have been developed. X-ray-based methods were used to study the fiber network in detail. The experiments have been performed with in-situ loading, which gives an increased understanding of important micromechanical mechanisms. In the numerical part of the project, models that take rate-effects into account have been developed. The models have been used to study the effect of production speed on, for example, crack nucleation when converting packaging material into a package.
Expected results and effects
The experimental methodology that has been developed makes it possible to study defects and their causes to be studied at a detailed level. The project has paved the way for industry to utilize experimental facilities such as MAXIV. The developed numerical models provide the packaging industry with tools for analyzing and optimizing fiber-based packages. The project has contributed to a significant improvement in the reliability of the numerical predictions. In addition to the technical results, the collaboration between industry and academia has been strengthened.
Planned approach and implementation
The project has been carried out in close collaboration between Lund University and Tetra Pak. The doctoral students and Post. Doc. who have been involved in the project have been supervised from both from both LU and Tetra Pak. Informal project meetings have been held on a weekly basis, while comprehensive project meetings have been held quarterly. In addition to this project, side projects where delamination in multilayer packaging materials have been initiated.
