A Three Dimensional Stress Transfer Model of SingleWalled Carbon Nanotube Reinforced Composites

摘要

In this paper axial stress, σn along the carbon nanotube (CNT) and interfacial shearrnstresses, τi in polymer nanocomposites were predicted using a three-dimensional stressrntransfer model. The analysis was done by deriving a second order differentialrnequation of CNT axial stress. The interfacial shear stress was obtained from the stressrntransfer equation. Appropriate boundary conditions were applied for unbonded endrncondition. The expression for the effective length, Leff was also determined. Further,rnthe variation of CNT axial and interfacial shear stresses at different fiber volumernfractions and different matrix properties were studied. Finally, the results obtainedrnfrom this model were compared with the results obtained by finite element analysis.
