We performed tensile tests on two carbon fibre/epoxy composites with continuous scanning using synchrotron computed tomography (CT). Both composites were cross-ply laminates, and two specimens were tested for each composite. The voxel size was sufficiently small to recognize individual fibres and fibre breaks. For each test, 16-19 volumes were reconstructed, cropped down to the 0° plies and analysed to track fibre break and cluster development. This dataset provides the last CT volume before failure for each of the four specimens as well as the individual fibre break locations in all reconstructed volumes. These data are then plotted against predictions from six state-of-the-art strength models. The target is that these data become a benchmark for the development of new models, inspiring researchers to set up refined experiments and develop improved models.
我们使用同步加速器计算机断层扫描（CT）对两种碳纤维/环氧树脂复合材料进行了连续扫描的拉伸试验。两种复合材料均为交叉铺层板，每种复合材料测试两个试样。体素尺寸足够小，能够识别单根纤维和纤维断裂情况。对于每次测试，重建了16 - 19个体积，裁剪至0°铺层并进行分析，以追踪纤维断裂和簇团发展情况。该数据集提供了四个试样中每个试样失效前的最后一个CT体积以及所有重建体积中单个纤维的断裂位置。然后将这些数据与六个最先进的强度模型的预测结果进行对比绘制。目标是这些数据成为新模型开发的基准，激励研究人员开展更精细的实验并开发改进的模型。
