Investigation Of Material Models For Fiber Reinforced Plastics
This master thesis was prepared by Michael Grüfelder, with support from J.A.M.E.S. Michael took the lead in its preparation, showcasing expertise and dedication to the research process.
Overview
Within the scope of this work, micro- and macro-mechanical models from the field of FRP are examined with regards to their applicability to additively manufactured conductive structures by multi-jet modeling. For this purpose, the material models are evaluated with regard to their applicability to the manufacturing process. Within the scope of a test program, different specimen gemetries are created, manufactured and subjected to mechanical tests. The results are evaluated and implemented in the material models. In addition, the specimens and their fracture surfaces are examined optically. In addition, numerical calculations are carried out in the form of FEM-simulations and computer-aided calculations based on the laminate theory. The results are classified according to the state of the art. Explanations are given for deviations in the measurement results from the models. An outlook on possible further investigations, taking into account the knowledge gained, complete the work.
