Abstract

The main aim of this paper is to define the interfacial stress transfer parameter s in the Callister model using the Pukanszky model. The parameter s is expressed by the polymer strength, carbon nanotube (CNT) size, and interfacial shear strength. The developed equation is applied to plot the roles of all parameters in the value of s. The reasonable outputs of the developed equation show its accuracy for the CNT nanocomposites. The interfacial shear strength directly handles the parameter s, but the matrix strength has no effect. Thin and long CNT increase the value of s, but thick and short CNT deteriorate it. However, the negligible variation of s within different ranges of CNT dimensions indicates that the CNT size slightly affects the value of s. The parameter B in the Pukanszky model directly handles the parameter s, which is logical because both B and s show the interfacial/interphase properties. In addition, although the aspect ratio of CNT determines the surface area of nanoparticles, it insignificantly manipulates the parameter s.

聚合物/碳纳米管纳米复合材料的界面应力传递参数建模

摘要

本文的主要目的是使用Pukanszky模型定义Callister模型中的界面应力传递参数s。参数s由聚合物强度，碳纳米管（CNT）尺寸和界面剪切强度表示。所开发的方程用于绘制所有参数在s值中的作用。所开发方程的合理输出表明了其对CNT纳米复合材料的准确性。界面剪切强度直接处理参数s，但基体强度没有影响。长而又薄的CNT会增加s的值，而长而短的CNT会使s的值变差。但是，s的变化可忽略不计在CNT尺寸的不同范围内表示CNT尺寸稍微影响s的值。Pukanszky模型中的参数B直接处理参数s，这是合乎逻辑的，因为B和s都显示界面/界面特性。另外，尽管CNT的长径比决定了纳米颗粒的表面积，但是它无关紧要地控制参数s。
