“…Generally, most of the proposed models for predicting the mechanical characteristics of CNT/polymer nanocomposites are valid only for a low range of CNT wt.% [45][46][47][48][49][51][52][53]. At low content of CNTs, the variation of the elastic modulus and the strength of polymer nanocomposites with a CNT weight fraction are nearly linear.…”

“…Also, a literature survey clearly indicates that the ROM has been extensively employed to predict the effective thermo-mechanical characteristics of PMNCs reinforced with aligned straight CNTs [46][47][48]. In another theoretical study, Mahmoodi and Vakilifard [49] developed a unit cell micromechanical model to investigate the electro-thermoelastic properties of the aligned straight CNT-reinforced smart nanocomposites. The influences of volume fraction, orientation and aspect ratio on the nanocomposite effective properties were studied [49].…”

In the present work, a new form of a Halpin-Tsai (H-T) micromechanical model is proposed to characterize the elastic modulus and tensile strength of carbon nanotube (CNT)-reinforced polymer nanocomposites. To this end, three critical factors, including random dispersion, non-straight shape and agglomerated state of the CNTs are appropriately incorporated into the H-T model. A comparison of the model predictions with some experiments on the CNT/polymer nanocomposites serves to verify the applicability of the proposed approach. It is found that the present predictions are in good agreement with the available experimental data. The results clearly reveal that for a more accurate prediction of the mechanical properties of the CNT/polymer nanocomposites, considering the random orientation, waviness and agglomeration of CNTs into the polymer matrix is critically essential. Also, some parametric studies are carried out to show the effects of volume fraction, non-straight shape, aspect ratio, mechanical characteristics and non-uniform dispersion of CNTs as well as matrix properties on the elastic modulus and tensile strength of CNT/polymer nanocomposites. The results reveal that it is necessary to eliminate the agglomeration and use the straight CNTs if the full potential of CNT reinforcement is to be realized.

Ever since several formations of polymer-based nanocomposites were reported, research on their modeling, characterization, and computerized analysis methodology has been extensively investigated to become a major academic field of advanced material science and technology. This paper mainly summarizes the multiscale computational analysis methodology for polymer nanocomposites. We also introduce various computational modeling approaches to characterizing the physical behavior of polymer nanocomposites, which are the molecular dynamics approach, and the continuum approach. Based on the various computational analyses, we summarize how the material properties and phenomenological behaviors of polymer nanocomposites were analyzed.

This article deals with the prediction of thermomechanical properties of fiber reinforced composites using several micromechanics models. These include strength of material approach, Halpin-Tsai equations, multi-phase mechanics of materials approaches, multiphase Mori-Tanaka models, composite cylindrical assemblage model, Voigt-Reuss models, modified mixture rule, Cox model, effective medium approach and method of cells. Several composite systems reinforced with short and long, aligned, random and wavy reinforcements were considered. In addition, different aspects such as fiber-matrix interphase, fiber-matrix interfacial thermal resistance, fiber geometry, and multiple types of reinforcements were considered to model the composites systems. The current study also presents some important preliminary concepts and application of developed micromechanics models to advanced nanocomposites such as carbon nanotube reinforced composite. Main contribution of the current work is the investigation of several analytical micromechanical models, while most of the existing studies on the subject deal with only one or two approaches considering few aspects.
