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

Abstract

In the current data article, we present detailed characteristics of voids in carbon/epoxy composite laminates, along with the original image stacks obtained via X-ray micro-Computed Tomography (micro-CT)1. 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 the ellipsoids that are fitted to 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 processing and interpretation of the data is reported in [1]. The data is hosted in the Mendeley Data repository at [2].

A review of applications of CT imaging on fiber reinforced composites

“…[7][8][9] XCT has been widely used for qualitative and quantitative assessments in the fields of fiber reinforced composites. [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] Compared to other destructive and 2D visualization techniques, such as scanning electron microscopy, optical microscopy, etc., XCT can provide information on the internal microstructure in both 2D and 3D formats. 26 Moreover, other non-destructive techniques, such as ultrasonic C-scan and Acoustic Emission, could detect the defects in the interior, but they cannot capture the high-resolution damage mechanisms which can be achieved using XCT.…”

The relation of porosity and creep behavior of glass fiber/epoxy composite: Design of experiments approach

“…The X‐ray micro‐CT is one of the most advanced techniques due to its high precision and ability to represent the composite, its constituents, and the void in a three‐dimensional form carrying out a nondestructive analysis. [ 7,8,12,13 ]…”
