The following dataset, comprised of SEM analysis images in .tif format, illustrates the findings of two key experimental categories related to the publication. The first dataset focuses on determining the optimal temperature for removing existing sizing from Carbon Fibres. Investigation was carried out across temperatures ranging from 300 to 600 degrees Celsius, with a 50-degree Celsius increment. The second dataset explores the morphology of the newly introduced sizing, incorporating FLG and CNT nanoparticles at various concentrations. These images, available in .tif format, offer a representative illustration of structural and surface morphologies in the materials studied, correlating with the examined parameters.

The next data are in .txt formal and related with mechanical test that have been performed on fibres.

Tensile tests and 3 point bending tests have been performed in resin impregnated and consolidated fibres. The tensile strength and bend strength have been calculated according to ASTMD4018 and ASTMD790 accordingly. Further analysis of the data have been performed in .xls file to calculate the average and standard deviation of each category. The categories were the fibres sized with different nanomaterials (FLG and CNTs) and in different ratios. Txt files have also been used for the analysis from nanoindentation and push out tests. Same principle was applied also here, since average and standard variation have been calculated in .xls file.

CSV file was extracted from a TGA machine. This analysis was performed to estimate the amount of sizing on reference and desized fibres. The software can also extract the results in image format .jpeg.

Lastly, image files in .png format have been extracted from optical microscope to calculate the angles formed from resin droplets on treated fibres.
