I am currently working on a temperature-dependent heat transfer model for PLA but have had difficulty finding documentation on its thermal diffusivity or conductivity. I am particularly interested in values for temperatures ranging from ambient (~26°C) to approximately 240°C.
If you have measured or found relevant data in your research, I would greatly appreciate any insights, references, or sources you could share.
Thank you in advance for your time and assistance.
Sure , but I did not work on temperature and its transfer , if I gain information on it ,I certainly share it with you
Finding temperature-dependent thermal properties for PLA can be challenging since its behavior changes significantly with temperature, especially near its glass transition (~60°C) and melting point (~170°C). Here are some key references and values:
If you need more precise data, I recommend looking into:
- Polymer handbooks like the "Polymer Data Handbook" (Oxford University Press).
- Experimental studies in journals like "Polymer Testing" or "Journal of Applied Polymer Science."
- Thermal analysis papers using DSC (Differential Scanning Calorimetry) and LFA (Laser Flash Analysis).
