Project C03

Characterization of hybrid porous materials for process design

To evaluate the material properties produced by the additive manufacturing process with porous materials, both porosity and material gradation must be measured and described using appropriate parameters. The challenge here is that established non-destructive methods, such as computed tomography (CT), require clear material boundaries. Additionally, there are no existing parameters to describe porosity and gradation at the micro-level.
As part of project C03, a virtual CT is to be developed, allowing for non-destructive reconstruction of material and porosity gradations. A mathematical model will be created to represent the interaction between the measurement object, X-ray radiation, and the detector. Simultaneously, a destructive reconstruction based on real samples will be developed. This will determine the parameters that can describe porosity and material gradation at the micro-level. By combining the synthetic measurement data from the mathematical model with the measurement data from real samples, a holistic, model-based measurement and evaluation methodology will be developed. The goal is to achieve a precise and comprehensive description of material properties that can be obtained both non-destructively and destructively.
