These files contain the data/software that was obtained/used in a research project using an Optical Backscatter Reflectometer (OBR) to obtain strain data of curing epoxy. Moulds of different length's were filled with liquid epoxy. In the middle of the epoxy, along the longest axis of the mould, the optical fibre sensed the strain acting upon the fibre due to the volume shrinkage. Additionally temperature probes were used to monitore the temperature in the epoxy. For the 40 cm and the 60 cm experiments these probes were arranged along the fibre, for the other experiments the probes were distributed randomly in the epoxy. Two Differential Scanning Calorimetry experiments were performed with temperature programs like the mean temperature of the 10 cm and the 60 cm curing experiments. See "001_Explanation of the data.txt" for a detailed description of the data. Please, see the "*.txt"-files in the respective subfolders for additional information. ATTENTION: The archives that contain the raw-measurement files are several GB big. It may take a while to open these. The results are to be published and the journal/article-title will be added as soon as possible. The software is published under the GNU General Public License, version 3.
