“…The fatigue test was interrupted for X-ray CT examination after 47,300, 57,300, 67,300, and 77,300 load cycles followed by failure of the specimen. The last interruption point was close to final failure (see also [1] ).…”

“…Ex-situ X-ray CT fatigue experiments were carried out on a 410 mm long butterfly shaped test specimen optimised for testing uni-directional (UD) fibre composites [2] with a 15 mm wide gauge section [1] . The material system considered was a glass fibre non-crimp fabric reinforced polyester composite with the layup [b/biaxial,b/0,b/0] s where “b” refers to the supporting backing layer and “0” to the UD fibre bundles, which are stitched to the backing layer.…”

“…The material system considered was a glass fibre non-crimp fabric reinforced polyester composite with the layup [b/biaxial,b/0,b/0] s where “b” refers to the supporting backing layer and “0” to the UD fibre bundles, which are stitched to the backing layer. The supporting backing layer is made from fibre bundles oriented in the directions 45°/90°/-45° and is significantly thinner than the UD layer of the fibre composite (see also [1] ). The backing fibre bundles have a significantly larger spacing than the UD fibre bundles and in some regions cross over one another due to their lay-up.…”

The data published with this article are high resolution X-ray computed tomography (CT) data obtained during an ex-situ fatigue test of a coupon test specimen made from a non-crimp fabric based glass fibre composite similar to those used for wind turbine blades. The fatigue test was interrupted four times for X-ray CT examination during the fatigue life of the considered specimen. All the X-ray CT experiments were performed in the region where unidirectional fibre fractures first became visible, and thereby include the damage progression in 3D in this specific region during fatigue loading of the specimen.

“…The scanned unidirectional (UD) glass fibre composite is a non-crimp fabric commonly used in the load-carrying parts of wind turbine blades, for details on this type of composite see [4] . The imaged sample of cross-sectional size 2 mm × 2 mm consists of UD fibre bundles stitched on backing bundles angled 45°, −45° and 90° with respect to the UD (0°) bundles.…”

A unidirectional (UD) glass fibre reinforced polymer (GFRP) composite was scanned at varying resolutions in the micro-scale with several imaging modalities. All six scans capture the same region of the sample, containing well-aligned fibres inside a UD load-carrying bundle. Two scans of the cross-sectional surface of the bundle were acquired at a high resolution, by means of scanning electron microscopy (SEM) and optical microscopy (OM), and four volumetric scans were acquired through X-ray computed tomography (CT) at different resolutions. Individual fibres can be resolved from these scans to investigate the micro-structure of the UD bundle. The data is hosted at https://doi.org/10.5281/zenodo.1195879 and it was used in Emerson et al. (2018) [1] to demonstrate that precise and representative characterisations of fibre geometry are possible with relatively low X-ray CT resolutions if the analysis method is robust to image quality.
