Aim
The diploma thesis examines the production of shaped bodies from alfalfa hay with regard to the design of their corner joints. For this purpose, possible joining processes are tested and adapted to the existing process chain. The aim is to achieve a technically simple process. Furthermore, it is being investigated how folding technologies can be used to form the semi-finished product into the forming tool without any problems. In the course of the tests, an overlap can be identified as a simple reinforcement of the corner joint, which is examined for its mechanical properties. In addition, the introduction of an additive is tested with regard to its influence on the strength of the alfalfa hay material. Starting with a plane joining test, the complexity of the test procedure is gradually increased. In a second step, a model corner joint is produced, the findings of which are then incorporated into the production of molded packaging.
