Modeling of the Interfacial Stress Transfer Parameter for Polymer/Carbon Nanotube Nanocomposites

Abstract: The main aim of this paper is to definethe interfacial stress transfer parameter s inthe Callister model using the Pukanszky model. The parameters is expressed by the polymer strength, carbonnanotube (CNT) size, and interfacial shear strength. Thedeveloped equation is applied to plot the roles of allparameters in the value of s. The reasonableoutputs of the developed equation show its accuracy for the CNTnanocomposites. The interfacial shear strength directly handlesthe parameter s, but the matrix strength has noeffect. Thin and long CNT increase the value ofs, but thick and short CNT deteriorate it.However, the negligible variation of s withindifferent ranges of CNT dimensions indicates that the CNT sizeslightly affects the value of s. The parameterB in the Pukanszky model directly handles theparameter s, which is logical because bothB and s show theinterfacial/interphase properties. In addition, although theaspect ratio of CNT determines the surface area ofnanoparticles, it insignificantly manipulates the parameters.
