Abstract: The main goal of this study is to investigate the interface characteristics of CNT and nanorope reinforced composite for both chemically bonded and non-bonded CNT/matrix interface. Initially, an analytical pull-out model has been developed to investigate the mechanism of stress transfer from CNT to polymer matrix for perfectly bonded interface. The pull-out model has been extended to deal with chemically non-bonded interface. Using the derived analytical solutions, parametric study, critical values of embedded length and Young?s modulus ratio for sample cases are also determined. Then, a shear-lag model has been developed for assessing the stress transferring mechanism from polymer matrix to CNT for non-bonded interface. Finally, a continuum model has been developed to investigate the stress carrying potential of nanorope in polymer resin as well as CNT in the rope system in the elastic regime. Parametric study has also been conducted for both perfectly bonded rope/resin interface and non-bonded CNT/CNT interface.
