On the dynamic mechanical properties of aramid fibers
Thread Content
Who has conducted experiments on the dynamic mechanical properties of aramid fibers? Could you give some guidance on the points to note in the multifilament DMA experiment? Thank you! For example, issues related to the selection of frequency, phase angle, and amplitude, as well as repetition problems!
It seems no one is paying attention to me! Maybe I should ask this question on another forum!
I’m afraid no one will be able to answer you; the technology related to aramid is highly confidential, and no information on it is available publicly.
There are post-processing companies in Changshu, Jiangsu; we can communicate.
I have conducted research on the dynamic tensile mechanical properties of aramid fibers, but I have not worked with DMA. It is recommended that the original poster study the principles and functions of the equipment more thoroughly and try different settings; I believe it will be possible to find satisfactory parameters.
Thank you to all my friends for their help! Thank you!
Hello, Brianren: Do you mean the dynamic mechanical property testing you mentioned refers to the dynamic mechanical properties of aramid fibers at high strain rates? What are your thoughts on the dynamic tensile properties of aramids from different manufacturers and of various grades (such as Kevlar 29 and Kevlar 49)? Is there any difference in the mechanical properties of aramids as the strain rate changes? I think there should be a difference, but the experimental conditions aren’t available to conduct tests at high strain rates! I’d like to hear your opinion; if indeed there is a difference, I’ll need to apply for a device in order to try it out! I would appreciate your advice!
Thank you! I’ll check it online! See what kind of post-processing is being done!
