Topic of the work:

The evaluation of filler, cavity and phase distributions and their proportions is of great importance in microscopic microstructure analyses. In practice, these statements are mainly made on the basis of cross-sectional preparations, which have a two-dimensional character. In contrast, volume statements are much more meaningful for a material evaluation and are naturally less prone to error. In this work, methods and conditions for the transfer of 2D measurements to the 3D volume are to be developed and evaluated. The first step is to generate CAD spherical cloud models. With the help of these models, 2D sectional images are then extracted from random planes in order to calculate area-related evaluations (radius, area of the circular areas) on the basis of these images.

The work is written in this working group:

The tests carried out in the microscopy laboratory at the Center for Plastics Analysis and Testing (KAP) provide significant support for industry and the institute’s own research in the validation of production parameters. Another focus is on systematic damage analysis in order to precisely identify the causes of faults and bridge the gap between research and industrial implementation. Through these analyses, the laboratory provides essential findings for the optimization of production processes and improved component quality.

Objective:

Within the scope of this research work, a statistical model with corresponding correction is to be created, with the help of which two-dimensional circle radius distributions can be converted into corresponding three-dimensional sphere radius distributions. The model should be prepared in such a way that it can be used in everyday work.
