Composites Part A

The data shows the experimental results for Mode-II fracture properties of glass-fiber/epoxy composite laminates, which consist of 14 layers of continuous filament mats and 6 layers of quadriaxial sewed fabrics. The experiments were conducted using an end-loaded split testing apparatus according to the standard ISO 15114:2014, and the results were processed using the experimental compliance method with correction factors considered. Note the crack length measurements include microcracking-zone length. Due to the transverse shear effects from the large thickness and the asymmetric fiber layup of the sub-laminates, the R-curves derived contain certain errors.

Static and cyclic fatigue test results on tensile lap shear of carbon/epoxy polymer composite bonded single-lap joints with surface treatments of manual sanding, grit blasting, peel-ply plus grit blasting.

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.

Flowability of EP-S-Al2O3 binary composite; AC conductivity, thermal conductivity and shear viscosity of EP-S-Al2O3 binary composites.

A set of natural silk and flax fibre reinforced composites have been prepared using resin transfer molding method. While maintaining a constant overall fibre volume fraction of the composites at 50 vol.%, the hybrid ratios of silk and flax were varied. From the dataset, a stiffening and strengthening effect from the introduction of flax can be seen for hybrid fibre composites compared to silk-only composites. In addition, the interlaminar shear strength (ILSS) was found to enhance with the introduction of flax in the hybrid fibre composites. It is noted that the ILSS test specimens failed in a combination of tensile and shear failure modes due to the ductility of both epoxy resin and silk fibres.
