High-resolution CT simulation of synthetically-generated volume porosity in continuous CFRP samples

In this study new insights regarding quantitative porosity determination using X-ray computed tomography (CT) could gained by using CT simulation tools to generated synthetical 3D data with a well known nominal porosity content. Therefore 1,988 typical microstructure elements such as individual carbon fibres, needle like micro voids as well some macro voids embeded in a polymer matrix (epoxy resin & polyamid 6) was used as geometrical imput. The results of the threshold-based segmentation methods in this paper are in good agreement with similar experimental results previously published by the authors.
