X-ray computed tomography of a unidirectional composite tape with microporosity features

The collection includes X-ray computed tomography measurements in 8-bit .tif format of a development-grade version of the unidirectional carbon fibre tape Toray Cetex® TC1225, manufactured by Toray Advanced Composites.The data was acquired using a Zeiss Xradia 520 Versa at a voxel size of 0.7788 µm, with a voltage-to-power ratio of 70/5 kV/W, an exposure time of 7 s, and a 2000x2000 pixel detector operating with no binning and 4x magnification. Three scan volumes were stitched together along the tape's longitudinal direction with a 20% overlap. The measurements were conducted at the Naturalis Biodiversity Center, Leiden (NL). A .txt file summarizing the dataset description is also included.Since multiple materials were present in the field of view of the original scan, only the region corresponding to the tape of interest has been cropped and reported here.

本数据集包含8位.tif格式的X射线计算机断层扫描（X-ray computed tomography）测量数据，对应由东丽先进复合材料公司（Toray Advanced Composites）生产的工程研发级单向碳纤维带Toray Cetex® TC1225。数据采用蔡司Xradia 520 Versa设备采集，体素尺寸为0.7788 µm，电压-功率比为70/5 kV/W，曝光时长7秒，使用2000×2000像素探测器，未开启像素分箱模式，放大倍率为4倍。沿胶带纵向以20%的重叠率对三个扫描体积进行了拼接。本次测量工作在荷兰莱顿的自然生物多样性中心（Naturalis Biodiversity Center）开展。数据集还附带了一份用于汇总说明的.txt文件。由于原始扫描视场内存在多种材料，本数据集仅裁剪并保留了与目标碳纤维带对应的区域。
