Complementary time-lapse datasets of x-ray computed tomography and realtime strain mapping for an ex-situ study of non-crimp glass fibre composites under fatigue loading

Data published in this paper corresponds to a time-lapse ex-situ experiment aimed at analysing the tension-tension fatigue damage in non-crimp glass-epoxy composites by multi-scale x-ray computed tomography (XCT) of the damage features and their timeline. This is then correlated with the strain fields obtained through digital image correlation (DIC). The XCT - DIC datasets by is acquired by interrupting mechanical fatigue tests at three time-steps, after the material has undergone 0 cycles, 70000 cycles, 80000 cycles, and 120000 cycles. This is one of the first multi-modally correlated datasets available for these types of non-crimp glass fibre composites, which explore the structure-property relationship in a time-dependent behaviour. This dataset can be used to explore glass-fibre composites microstructure under a progressive damage scheme and can be used to test and train a plethora of image processing and analysis techniques. This dataset can also be used as an attempt to model the fatigue behaviour of quasi-unidirectional non-crimp fibre composites by image-based simulations.
