Investigation Of Material Models For Fiber Reinforced Plastics

This work examines micro- and macro-mechanical models from the field of FRP for their applicability to additively manufactured conductive structures through multi-jet modeling. The material models are evaluated concerning their suitability for the additive manufacturing process. A comprehensive test program is conducted, creating and manufacturing different specimen geometries, which are then subjected to mechanical tests. The test results are evaluated and incorporated into the material models. Additionally, optical examinations of the specimens and their fracture surfaces are performed. Numerical calculations, including FEM simulations and computer-aided calculations based on laminate theory, are carried out. The results are analyzed and compared to the current state of the art, with explanations provided for any deviations from the models. The study concludes with an outlook on potential future investigations based on the insights gained.
