A dataset of voids’ characteristics in multidirectional carbon fiber/epoxy composite laminates, obtained using X-ray micro-computed tomography

In the current data article, we present detailed characteristics of voids in carbon/epoxy composite laminates as well as the original image stacks, obtained via X-ray micro-Computed Tomography (micro-CT) . Five different lay-ups are produced with altering the recommended cure cycle in order to intentionally induce voids in the material. For each lay-up, an image stack (consisting of tomographic slices) and a dataset are provided. The image slices are in 8-bit TIF format. The datasets (spreadsheets) include the volume, size parameters, shape parameters, orientation, and location of all the detected voids in the specimen. The segmentation of the images and quantification of voids are performed in VoxTex, an in-house software for processing of micro-CT results. The data is linked to a Data in Brief article "Mehdikhani et al., A dataset of voids’ characteristics in multidirectional carbon fiber/epoxy composite laminates, obtained using X-ray micro-computed tomography, DIB 27 (2019) 104686" and linked to the article "Mehdikhani et al. Detailed characterization of voids in multidirectional carbon fiber/epoxy composite laminates using X-ray micro-computed tomography. Comp Part A 125 (2019) 105532".

在本期数据论文中，我们详尽阐述了碳/环氧复合层压材料中孔隙的详细特征，以及通过X射线微计算机断层扫描（micro-CT）获得的原始图像序列。通过调整推荐的固化周期，我们成功制备了五种不同的层压结构，以故意在材料中诱导孔隙。对于每一种层压结构，我们提供了图像序列（由断层切片组成）和数据集。图像切片采用8位TIF格式。数据集（电子表格）包括所有检测到的孔隙的体积、尺寸参数、形状参数、方向和位置。图像的分割和孔隙的量化是在VoxTex软件中完成的，该软件是用于处理micro-CT结果的内部软件。数据与《Data in Brief》上的文章“Mehdikhani等人，利用X射线微计算机断层扫描获取的多向碳纤维/环氧复合层压材料中孔隙特征的数据库，DIB 27 (2019) 104686”相链接，并链接至文章“Mehdikhani等人，使用X射线微计算机断层扫描对多向碳纤维/环氧复合层压材料中孔隙的详细表征。Comp Part A 125 (2019) 105532”
