Due to the limited budget, we could not perform the two TGA modes (over a range of temperature and over time). Information about degradation of ABS with temperature have been published by several authors. Moreover, DSC analysis already gives an indication about the thermal stability over a range of temperature (up to 300 °C). Then, we decided to evaluate the thermal strength of our drone at 120°C during 2 hours. The results regarding Flexifil and ABS are shown on on the figure below. The black curve corresponds to Flexifil and the red one to ABS. For both of them, the weight does not decrease below 99.5% of it initial weight, which means that the two polymers are thermally stable (no evaporation, decomposition…) during the two hours at 120°C.Using the drone at 120°C during a long time (2 hours) should then not lead to polymer composition changes. However, multiple uses means multiple thermic cycle and this has not been investigated, so the stability over several uses is not guaranteed.
