I want to predict the mechanical and thermal properties of polymer nanocomposites using numerical models/analytical/FEA/micromechanics method?
Anyone worked in this field and if so help me in this regard?
i am using HDPE-Copper Nanocomposite and having thermal and mechanical properties obtained from different experimental test.
Hii Muthiah,
Have a look to the following publications :
I.H. Tavman Powder Technology 91(1997)63
D. Kumlutas and I.H. Tavman J. of Thermoplastic Composite Materials 19 (2006)440
Have a look at the following publications:
T.S. Chow: The effect of particle shape on the mechanical properties of filled polymers, Journal of Materials Science 15(8) (1980) 1873–1888.
J.D. Eshelby: Proc. Royal Society London, 1957.
K.Y. Lee et al.: Thermal expansion behavior of composites based on axisymmetric ellipsoidal particles, Polymer 48(14) 2007 4174–4183.
K.Y. Lee and D.R. Paul: A model for composites containing three-dimensional ellipsoidal inclusions, Polymer 46(21) (2005) 9064–9080.
I found these useful in understanding the effects of particle size, size distribution and aspect ratio on various properties.
Use ansys. I did that and predict mechanical properties oc CNT reinfirced nano composites. You just model your nano composite and apply B.Cs.
With all due respect, I disagree. Based on my understanding of polymer nanocomposites (i.e., the filler particles should at least be smaller than 1 µm, preferably 100 nm), they develop unpredictable inner structures:

In later years, I have worked in more detail on this and found that such systems are (thermondynamically spoken) non-equilibrium systems which follow self-organisation rules. That means you can predict their properties as well as you can predict weather or the result of a soccer game ...
