From a modelling standpoint, the morphology of additively manufactured (AM) high-performanceshort fiber reinforced polymer (SFRP) are essential to characterize, yet this task poses greatchallenges. The method presented extracts individual fibers from tomographic scans andproduces a segmentation that is accurate across a large range of fiber filling ratios (5-40wt.%), needs minimal human input and is scalable to full-sized datasets containing ~105individual fibers. In addition, this tool allows the analysis of the correlated length and orientationdistribution of fibers, and the quantification of shear-induced alignment and fiber breakage.The method is validated by successfully reproducing the segmentation of (continuous) fiberreinforced composites published in 2 separate studies and by predicting the fiber volume fractionand material density directly from the tomographic data of SFRPs. The output can serve as a basisfor constituent-level mechanical modelling, and to gain insight into the relationship betweenprocessing parameters, morphology and mechanical behavior of SFRP. The full source code andimaging data are attached to this publication.
