Linear rheology measurements: temperature ramp tests of two commercial samples of poly(lactic acid)

This data set includes the measurements of the temperature ramp (TRamp) tests performed during Petra Bacova's stay at IESL-FORTH in Heraklion, Greece in summer 2024. The measured materials are two commercial samples of poly(lactic acid) (PLA): recycled PLA and PLA3D850. The technical sheets downloaded from the producer [1] are included in the directory. The data are saved in two formats, txt and RSD07 format used in rheometers of TA Instruments. The TRamp tests were performed with ARES rheometer. Each file is labeled as follows: DTempRamp_procedurewithtemperaturerange_referencegap_strain_frequency_rate The measurements with high torque were done with a torque transducer 2 and are labelled with trans2 in the end of the file name. The rest of the measurements was done by using the transducer 1 in ARES instruments. The measurements started at the temperature higher than the melting temperature of the samples (cooling procedure) and the heating procedure was performed right after the end of the cooling, with a maximum delay of 5 minutes. The sample preparation as well as the setting of the reference gap and other parameters is described in the technical note elsewhere. [2] The dynamic strain sweep and dynamic frequency sweep measurements of these samples are publicly available. [3] Each directory also includes a gnuplot file which plots the results in eps format.
