A video describing the test-setup can be found in the following link: https://panopto.dtu.dk/Panopto/Pages/Viewer.aspx?id=50c10945-0612-4126-9e99-b00700cfbaf2&start=0 

The data-set cover single fiber test of a carbon and glass fiber in the gauge section range from 20-80 mm for carbon fiber and from 40-80 mm for glass fiber. There are three files for each gauge-section:

... Data.xslx: The individual tensile curves with one sheet for each fiber. There are around 150 fibers in each set

... Results.xslx: One excel-sheet containing a summary of the parameters obtained for the individual fibers.

....Figures.doc: Word file showing a plot of the graphs 

In addition to this, there are for the carbon and glass fiber case a test setup complience calculation saved in the 

.... Compliance.xslx excel-sheet

and SEM scans of a large approximately 2x20 mm cross-section of a pultruded profile based on the carbon fibers. This scan can be used for validating the fiber diameter distribution found in the single fiber testing. The SEM scan is saved in the

Carbon_HyFisyn... files

This set of files also include a matlab file (.m) which are used for determine the fiber volume fraction of the composite. 

Scripts to plot and analysing the data can be found on the following places:
