Abstract


This work is a part of an on-going effort to develop effective methods and algorithms enabling automated conversion of X-ray Computed Tomography (CT) scan data into finite element (FE) models for as-built composite parts. In particular, this paper is focused on the automated methods of segmentation of composite plies in X-ray CT scans and finding resulting ply waviness as well as local fiber directions and ply orientations, including average fiber misalignment and fiber direction variability. Sample applications of the proposed algorithm are provided for as-manufactured tape composite laminates as well as additively manufactured composites. Effects of X-ray CT scan quality on the algorithm performance are demonstrated.
