With the advent of wearable electronics, the urge to devise new and flexible energy storage devices to power up wearable systems has steadily risen over the past few decades. Wearable fabric‐based supercapacitors have emerged as a fantastic solution for powering up these systems. Functionalizing fabric surfaces with electroactive materials has proven to be the ideal way to fabricate high‐performance wearable supercapacitors. In this review, the recent progress in functional fabric‐based wearable supercapacitors is summarized. The article begins with the introduction of different fabric structures and outlining the functional materials implemented in wearable supercapacitors. The emphasis shifts toward summarizing the fabrication of functional fabric‐based electrodes according to different fabric architectures. Then, different novel fabric‐based supercapacitor configurations, the current state of integration, and the durability of such devices are analyzed. The review is concluded by emphasizing the existing drawbacks, envisaging potential applications, and, most importantly, the future perspective of the technology.

“…This model is developed based on the combination of a unit cell model with microstructural parameters and the development of micromechanics, but it has high computational costs and cannot be applied to stamping analysis [8]. At the mesoscale, a single cell model for woven materials can effectively characterize the internal structure of composite materials or the mechanical behavior of a single fiber, but it cannot effectively indicate the performance of composite materials woven from a large number of fibers and is not suitable for analyzing their forming process [9]. At the macro level, phenomenological energy functions can be used to describe the macroscopic mechanics of fiber-reinforced hyperelastic materials, which can be mainly divided into statistical mechanical models, strain tensor component forms, and strain invariant forms.…”

The present paper introduces an innovative strain energy function (SEF) for incompressible anisotropic fiber-reinforced materials. This SEF is specifically designed to understand the mechanical behavior of carbon fiber-woven fabric. The considered model combines polyconvex invariants forming an integrity basisin polynomial form, which is inspired by the application of Noether’s theorem. A single solution can be obtained during the identification because of the relationship between the SEF we have constructed and the material parameters, which are linearly dependent. The six material parameters were precisely determined through a comparison between the closed-form solutions from our model and the corresponding tensile experimental data with different stretching ratios, with determination coefficients consistently reaching a remarkable value of 0.99. When considering only uniaxial tensile tests, our model can be simplified from a quadratic polynomial to a linear polynomial, thereby reducing the number of material parameters required from six to four, while the fidelity of the model’s predictive accuracy remains unaltered. The comparison between the results of numerical calculations and experiments proves the efficiency and accuracy of the method.

“…Various deformation mechanisms, including the axial stretch of fibers and the shear of fabrics, are considered to derive the internal nodal loads. [12][13][14] While continuous and semi-discrete models can efficiently predict overall fabric deformation, they fail to illustrate the deformation mode and mechanics of individual tows when the fabric is subjected to external loading, because these modeling approaches are based on analyses in which individual tow deformation is smeared in the effective fabric deformation responses.…”

Fabric draping, which is referred to as the process of forming of textile reinforcements over a 3D mold, is a critical stage in composites manufacturing since it determines the fiber orientation that affects subsequent infusion and curing processes and the resulting structural performance. The goal of this study is to predict the fabric deformation during the draping process and develop in-depth understanding of fabric deformation through an architecture-based discrete Finite Element Analysis (FEA). A new, efficient discrete fabric modeling approach is proposed by representing textile architecture using virtual fiber tows modeled as Timoshenko beams and connected by the springs and dashpots at the intersections of the interlaced tows. Both picture frame and cantilever beam bending tests were carried out to characterize input model parameters. The predictive capability of the proposed modeling approach is demonstrated by predicting the deformation and shear angles of a fabric subject to hemisphere draping. Key deformation modes, including bending and shearing, are successfully captured using the proposed model. The development of the virtual fiber tow model provides an efficient method to illustrate individual tow deformation during draping while achieving computational efficiency in large-scale fabric draping simulations. Discrete fabric architecture and the inter-tow interactions are considered in the proposed model, promoting a deep understanding of fiber tow deformation modes and their contribution to the overall fabric deformation responses.
