The research plattform ARENA2036 (Active Research Environment for the Next generation of Automobile) is a long term project funded by the Federal Ministry of Education and Research Germany. Within this project four sub-projects are located. DigitPro, one of those sub-projects, deals with the development of a Digital Prototype. A closed simulation process chain for braided composite structures is built which not only covers different simulation disciplines such as crushing or process analysis, but also various software solutions and material models. The main goal is to use the digital prototype to decrease the weight of an automotive structure by 10% and the development time by 50%.
In this project one of the focused manufacturing processes for composite structures is the braiding technology followed by an infusion process. A complete numerical prediction is necessary for the braiding as well as for the infiltration process to decrease the development time and to increase the mechanical performance of braided structures. These results can be used as input for structural and crash simulation.
Within this work the results of the project DigitPro including an overview of the newest developments in braiding and infiltration simulation and especially in the transfer of the necessary data from one process to the next is given.
