“…Among all others, CNTs have been emerged as the ideal candidates for multifarious applications due to their remarkable thermoelastic and physical properties. The quest for utilizing the remarkable thermomechanical properties of CNTs has led to the emergence of a new area of research that involves the development of nanocomposites . These studies revealed that the addition of a small fraction of CNTs into a polymer matrix introduces significant improvement in the multifunctional properties of microcomposites and nanocomposites.…”

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.

“…One of the main assumptions for deriving the SUC micromechanics model is the perfect bonding condition at the interface between the sub-cells of the RVE. [28][29][30][31] Additionally, it is supposed that the applied normal stress over the RVE does not present any shear stress inside the sub-cells of the RVE. [28][29][30][31] The equilibrium conditions in normal directions between the applied global stresses ( " S l ) (l ¼ x, y or z) over the RVE and local stresses ( ij l ) within each subcell of the RVE are given by…”

In this work, a unit cell-based micromechanical model with a proper representative volume element is proposed to evaluate the coefficients of thermal expansion of carbon nanotube-reinforced polyimide nanocomposites. The model takes an interphase between carbon nanotube and polyimide matrix into account which characterizes the non-bonded van der Waals interaction between two phases. The effects of some important parameters on the coefficients of thermal expansion such as thickness and adhesion exponent of interphase, temperature deviation as well as volume fraction, diameter and waviness of carbon nanotubes are investigated in detail. It is found that the interphase plays a critical role in determining the coefficients of thermal expansion and should be incorporated into the modeling of nanocomposite. According to the obtained results, there exists a specific value for carbon nanotube diameter beyond which further increasing in carbon nanotube diameter does not affect the coefficients of thermal expansion of nanocomposite. Also, the results reveal that the carbon nanotube waviness has a significant influence on the coefficients of thermal expansion of the nanocomposite. The results of the present model are compared with those of finite element method and a very good agreement is pointed out.

“…Hassanzadeh-Aghdam et al. 17 developed a three-dimensional micromechanics-based analytical model to explore the influence of interphase on the thermo-mechanical properties of three-phase continuous composites. The results exhibited that the effect of interphase on the thermo-mechanical properties of fibrous composites in the transverse direction is more significant than that of the fiber composites in the longitudinal direction.…”

The objective of this paper is to investigate the coupled effects of interphase and thermal residual stress on the biaxial initial yield surfaces of metal matrix composites using the simplified unit cell micromechanical model. The representative volume element of the composite consists of three phases, including unidirectional silicon carbide (SiC) fiber, titanium (Ti) matrix, and the interphase region between the fiber and matrix. It is found that the interphase slightly affects the initial yield surfaces of metal matrix composites without thermal residual stress. However, the results reveal that as the thermal residual stress is considered in the micromechanical modeling, the effect of interphase on the response of metal matrix composites becomes much more significant. The effects of the SiC volume fraction, interphase parameters including thickness and material properties on the yielding behavior of the metal matrix composites are examined. To demonstrate the validity of the model, comparisons are carried out between the results of the present model and other micromechanical methods as well as experiment. The extracted results could be useful to guide the modeling and design of a wide range of multiphase metal matrix composites.
