Abstract Details

2011, Master of Science in Engineering, University of Akron, Mechanical Engineering.
A new method has been developed to determine the interfacial friction between carbon nanotubes (CNTs) and polymer matrix. A stripe made of Poly(methyl methacrylate) PMMA was imprinted as a specific contact pattern on a CNTs substrate with an ordered nanotube array. By simultaneously measuring the vertical displacement and monitoring load in the decohesion process, the interfacial friction was calculated based on analytical formula from micromechanics. To extract quantitative results, a 3D finite element model for the decohesion test was developed and a cohesive zone model was used to predict the complex equilibrium of crack front. The model predicts that the interfacial energy is a function of maximum separation force, sample size and CNTs height, and the model agrees well with full numerical results over a wide range of stripe and substrate property values. The overall method is applied here to determine the interfacial friction of CNTs/PMMA Matrix.
