“…The Mori-Tanaka model was proposed by Mori and Tanaka, (1973). The model exhibits a rational approach and an effective field theory for inhomogeneity in an infinite medium, to relate the average fibre stress and fibre strain, with the matrix medium (Mishra & Das, 2020). The Mori-Tanaka approach is modelled as follows:…”

The increasing demand for good and improved polymeric composites has led to a surge in the number of researches on hybrid composites, strengthened and enforced with the natural fibres. This paper mainly analyses and presents the attributes of hybrid composites made from natural fibres and carbon nano-tube (CNT) nanoparticles. A novel hybrid composite considered in this research includes kenaf and coir fibres with CNT nanoparticles embedded in an epoxy matrix. The proposed hybrid nanocomposite’s elastic features are calculated by using different analytical models like Chamis, Mori-Tanaka, Nielson elastic models etc and also with the help of Representative Volume Element Analysis (RVE). The content of fibre volume is varied in four different samples and it is found that upon varying the content of fibre volume, the mechanical properties like longitudinal modulus and transverse modulus got affected. The results evaluated from different analytical models are observed to be in good agreement with each other and also with the results of RVE analysis.

This research investigates the effect of adding graphene nano-sheets (GNSs) on the elastic and piezoelectric responses of PZT-7A piezoelectric fiber/polyimide hybrid composites. The constructional feature of this hybrid composite is such that unidirectional PZT-7A fibers are embedded into the GNS-filled polyimide material. A nested micromechanical modeling strategy based on the Mori-Tanaka scheme is developed to predict the effective properties of PZT-7A/GNS/polyimide hybrid composites. Parametric studies are performed in order to examine the influences of volume fraction, agglomeration and rolling-up of GNSs, and PZT-7A volume fraction on the piezoelectric hybrid composite coefficients. The results indicate that the elastic and piezoelectric properties of PZT-7A/polyimide composites can be improved by the uniform dispersion of GNSs. However, it is observed that the formation of GNS agglomeration into the polyimide matrix has a serious negative effect on the equivalent properties of piezoelectric hybrid composites. The present predictions are also compared with other results reported in the literature. It is believed that the modeling approach and outcomes of this research may help to design these kinds of novel and highly promising piezoelectric hybrid composites.

Several methods and theories are developed to predict effective properties of piezoelectric composites [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Analytical methods are applied to predict effective properties of 1-3 piezoelectric composites [18][19].…”

The effect of fiber cross-section on effective elastic and piezoelectric coefficients of piezoelectric fiber reinforced composites (PFRC) is investigated through two micromechanical analyzes viz. modified strength of materials (MSM) approach and energy approach. Results are verified with that of strength of materials (SM) approach available in the literature. A constant electric field is considered in the direction transverse to the fiber direction and is assumed to be same both in the fiber and matrix phases. It is observed that MSM and strength of materials (SM) approach predictions for the effective piezoelectric coefficient of the PFRC assessing the actuating capability in the fiber direction are in excellent agreement and also when the fiber volume fraction exceeds a critical value, this effective piezoelectric coefficient becomes significantly larger than the corresponding coefficient of the piezoelectric material of the fiber as investigated by both SM and MSM approaches. However, results of energy approach differ from both MSM and SM results and effective piezoelectric constant never exceeds to that of fiber as obtained by energy approach. It has been found for the piezoelectric fibers, cross-section of fiber has insignificant effect on the effective properties as predicted by MSM and energy approaches. Nomenclature
