Micro-CT Datasets of tape and laminate specimens of Staple Fiber Yarn Composites with 1 %, 20 % and 50 % Stretching made from recycled Carbon Fibers

This dataset contains X-ray computed tomography (CT) scans of recycled carbon fiber reinforced polymer (rCFRP) composites manufactured from staple fiber yarns. Two specimen types were investigated: tapes and laminates. For each specimen type, three stretching levels were considered: 1%, 20%, and 50%. For every combination of specimen type and stretching level, three independent specimens were scanned, resulting in a total of 18 CT datasets. The scans were acquired using a Zeiss Xradia 520 Versa X-ray microscope. All scans were reconstructed with a voxel size of 0.8 µm. Dataset Contents The dataset includes: Reconstructed CT image volumes provided as TIFF image stacks, compressed in ZIP archives. Corresponding scan metadata files in JSON format containing acquisition and reconstruction parameters. File Naming Convention Files belonging to the same specimen share a common identifier following the pattern: <StretchingValue>_<SpecimenType>_<SpecimenNumber> where: StretchingValue = 1, 20, or 50 (% stretching) SpecimenType = Tape or Laminate SpecimenNumber = specimen replicate identifier (1–3) File Types Reconstructed CT images Filename pattern: <StretchingValue>_<SpecimenType>_<SpecimenNumber>_tiff.zip <StretchingValue>_<SpecimenType>_<SpecimenNumber>_tiff_crop.zip (cropped datasets, where available) Metadata Filename pattern: <FullFilePath>.meta.json The metadata files provide the acquisition settings and reconstruction information associated with each CT scan.
