Research on the mechanical properties of the CNT composites
Carbon nanotube (CNT) can be used as a good reinforcement embedded into polymer matrix.However,properties of composites reinforced by CNT cant be improved efficiently,because of the damage of interface between CNT and polymer in CNT composites.In this paper,the cohesive zone model (CZM) was employed to express the damage and fracture of interface between CNT and the epoxy matrix.The key parameters of the bilinear CZM were deduced based on the existing theory work.The whole deformation and fracture process of the interface has been revealed through the FE simulation results.The performance of the interface decides the mechanical property of the CNT composites and the stress-strain curve of composites has been plotted.It is with great importance to study the mechanical property of the interface to improve the performance of CNT composites.
