Abstract

This data in brief article describes a dataset used for an X-ray computer tomography aided engineering process consisting of X-ray computer tomography data and finite element models of non-crimp fabric glass fibre reinforced composites. Additional scanning electron microscope images are provided for the validation of the fibre volume fraction[1-15].The specimens consist of 4 layers of unidirectional bundles each supported by off-axis backing bundles with an average orientation on ±80° The finite element models, which were created solely on the image data, simulate the tensile stiffness of the samples. The data can be used as a benchmark dataset to apply different segmentation algorithms on the X-ray computer tomography data. It can be further used to run the models using different finite element solvers.

The presented data consists of three reconstructed X-ray computer tomography scans of non-crimp fabric reinforced glass fibre composites The scans were taken with Zeiss Xradia 520 Versa at DTU Roskilde, Denmark.The image data for all three scans is saved and uploaded as .nil-file. Each scan consists of three single scans that were stitched together in order to increase the field of view. For the acquisition a detector with 2000 × 2000 pixel was used.Different settings for the accelerating voltage, power, exposure time, number of projections and binning were chosen.A full rotation of the sample was performed and the optical magnification as well as the distance sample to source and sample to detector was kept constant. Further details can be found in . For each scan a .pdf-file with settings from the scanner is uploaded.
