On the importance of experimental material data in the design of short fiber reinforced lightweight AM components

by H. Völkl, S. Wartzack - mfk-KT

Additive manufacturing is becoming increasingly important for structural components. Experimental material data are absolutely essential for their design, especially when using fiber-reinforced polymers: While these offer great lightweight potential, they also exhibit material behavior that is complex to model. In this presentation, material characterization, model calibration and validation will be shown for a short-fiber-reinforced thermoplastic manufactured additively using the FLM process. Potentials and application possibilities for the use of such material models in Design for Additive Manufacturing will be exemplified.
