Micromechanics Model for Wavy CNT Nanocomposites with Weakened Interface

FEIYAN ZHU, GUNJIN YUN

Abstract


This study presents an efficient approach for deriving the modified Eshelby tensor for wavy CNT nanocomposites with weakened interface to be used in the Mori-Tanaka model. Waviness and interfacial damage between matrix and CNT fillers are two main features that influence elastic stiffnesses of CNT nanocomposites. However, both have yet been taken into account at the same time for micromechanics model. Using the proposed model, we investigated influences of the waviness, damage level, volume fraction, interfacial damage and orientation on the effective stiffness of both 3D randomly oriented and aligned CNT nanocomposites. Increases of the volume fraction showed positive reinforcing effect while the waviness and interfacial damage decreases the effective stiffness. The proposed model is expected to provide realistic effective elastic stiffness of CNT nanocomposites.
