Can any one sugget where should I found the DMA test results of pure epoxy. I need to find out the prony series from this DMA test results to define visco-elastic material property.
Dear Phanindra Reddy Ravi,
I guess first of all you will need to know which epoxy resin do you have (DGEBA is very popular). Normally, epoxy resins are in liquid form and you can find in literature their rheological properties. In order to obtain a crosslinked material, epoxy resins precise a crosslinker (DDM is very popular). In this last case, you may find some viscoelastic properties in literature. So, in order to find the information you need, I suggest the following:
1) Find out which epoxy monomer do you have. For example: DGEBA.
2) Find out their rheological properties.
3) Find out which crosslinker do you use, or you are interested in. For example: DDM.
4) Search in literature for the viscoelastic properties of the system of interest. In the example, it should be DGEBA/DDM system.
Hope it helps!
Regards!
