Elastic properties of CNT-polymer nanocomposites
Elastic properties of CNT/Polymer nanocomposites are calculated based on a multi-layered Generalized Self-Consistent (GSC) scheme. A CNT-polymer interface is considered as a distinct phase.
Three phases (CNT, interphase, polymer matrix) are considered and embedded in an infinite effective medium.


Predicted axial moduli values of nanocomposite vs. CNT content. (a) Axial modulus of an ideal nanocomposite with perfectly aligned carbon nanotubes; (b) modulus of nanocomposites with (3D) random-oriented CNTs. The shown moduli are normalized to the modulus of the polymer matrix.

A three-phase Shear-Lag micromechanics model has also been developed in order to evaluate the CNT aspect ratio effect on mechanical properties.
Predicted effect of CNT aspect ratio on the axial Young's modulus of the nanocomposite for a case of perfectly aligned CNTs. The shown moduli are normalized to the modulus of the polymer matrix.
