Interfacial Shear Strengths of Carbon Nanotube Reinforced Polymer Composites

摘要

In this study, we investigates the interfacial properties nanoreinforced polymer composites by simulating a nanotube pull-out experiment. An atomistic description of the problem is achieved by implementing constitutive relations that are derived solely from interatomic potentials. Specifically, we adopt the Lennard-Jones (LJ) interatomic potential to simulate a non-bonded interface, where only the van der Waals (vdW) interactions between the CNT and surrounding polymer matrix are assumed to exist. The effects of CNT embedded length, the number of vdW interactions, the thickness of the interface on the interfacial shear strength (ISS) are investigated and discussed.
