This dataset includes four large field-of-view scanning electron microscopy (SEM) images together with associated Matlab scripts aimed for the analysis used in the joint publication. Each of the four stitched images is generated from a large number (between 15500 and 24500) high-resolution (195nm/pixel) scans, which have been stitched into four images stored as tiff-files. The images show the cross-section of fiber bundles in composite laminate and are well-suited for local fiber volume determination. The image resolution corresponds to between 600 and 2000 pixels covering each fiber. The imaged samples are from composite laminates with an overall fiber volume fraction in the range of 55% to 60%. The local fiber volume fraction is found both for the full cross-section, as an average fiber volume fraction over the individual bundles, and as a local fiber volume fraction found in a moving averaging box with a size corresponding to 5×5 fiber diameter (80×80 µm) areas.
该数据集包括四张大型视野扫描电子显微镜（SEM）图像以及相关的Matlab脚本，这些脚本用于联合出版物中所使用的分析。这四张拼接图像中的每一张都是由大量（15500至24500之间）高分辨率（195nm/像素）扫描生成的，这些扫描已拼接成四个存储为tiff文件的图像。这些图像展示了复合层压板中纤维束的横截面，非常适合用于局部纤维体积的测定。图像分辨率对应于覆盖每根纤维的600至2000像素。成像样本来自纤维总体积分数在55%至60%范围内的复合层压板。局部纤维体积分数既可以在整个横截面中找到，作为各个纤维束上的平均纤维体积分数，也可以在一个大小对应于5×5纤维直径（80×80 µm）区域的移动平均框中找到局部纤维体积分数。
