Raw tensile dynamic mechanical analysis (DMA) data of a DGEBA epoxy for wind turbine blades: isothermal frequency sweeps and multi-frequency temperature sweeps

These data can be used to build time–temperature superposition (TTS) master curves.</p><p dir="ltr">(B) Four temperature sweeps at a heating rate of 2 K/min from about −20 °C to 125–150 °C, each at one constant frequency (1, 10, 50 and 100 Hz). These data show the glass transition and its dependence on frequency.</p><p dir="ltr">Each file is a plain-text export from the instrument software with two header lines (column names and units) followed by the measured data: sample and setpoint temperature, time, frequency, force and displacement amplitudes, static force and displacement, phase angle, storage, loss and complex moduli (E′, E″, E*), loss factor (tan δ), compliances and dynamic viscosities.

The numerical content is unmodified. The file names give the setpoint temperature of each frequency sweep (e.g. Epoxy_DMA_FreqSweep_T050C.txt) and the frequency of each temperature sweep (e.g. Epoxy_DMA_TempSweep_f010Hz.txt). README.txt describes all files, variables and test conditions.</p>
