“…The geometrical model of the plain glass weave was modeled to predict the engineering constant values to determine the mechanical properties. The same model was further used for other weave fabrics to determine the engineering constant [54]. The geometrical model can also be generated using the different mathematical functions, which can be further implemented in the software to develop the geometrical model [55].…”

Polymeric composites are used worldwide due to their enhanced applications in various sectors such as automotive, defense, aerospace, marine, and many others. Its lightweight and high‐strength applications make it convenient to use in high‐security fields such as defense and aerospace. Thus, it is essential to characterize composite materials for product development. Numerical simulation of composites has advantages over experimental characterization. The paper presents the mechanical behavior of polymer textile composites, employing geometrical modeling and a numerical simulation approach, under several loading conditions such as tension, compression, flexural, and impact loading. Failure mechanisms are also discussed with different failure modes and damage criterions. This review paper is limited to high‐strength fibers, such as carbon, Kevlar, and Glass fibers in unidirectional and woven formation. Various test specimens used in mechanical characterizations are presented with significant research summaries. Classification charts are also provided for a better understanding of the numerical simulation approach for characterizing the mechanical behavior.

The paper presents the results of an investigation in the area of numerical analysis and designing of lightweight composite disks reinforced with continuous fibres. The problem of the optimal layout of reinforcing fibres in the matrix domain in order to obtain the minimal weight of the disk with assumed mechanical properties is considered. The case of the creation of linear and curvilinear fibres is discussed. An adequate model of the composite structure is presented as well as the optimisation task for this type of design problem, and the method of solving this task is formulated in the paper. The design problem is illustrated by a simple numerical example.

“…This method has been numerously used to predict mechanical properties of woven and braided composites. 9–11 In the case of weft-knitted composites, limited studies are available. The first attempt made by Ramakrishna 12 calculates only in-plane properties of the composite, but in three-dimensional analysis the entire stiffness matrix is required.…”

Design and analysis of parts constructed from weft-knitted textile composites need the elastic and fracture behavior of the composite. To avoid time-consuming and expensive experimental procedures, micromechanical models and finite element simulations can be used to estimate stiffness matrix of these composites. In the present study, at first, a 3D model of a plain weft-knitted fabric is presented. Then a micromechanical approach is proposed to derive the mechanical properties of the weft-knitted composite using this geometrical model. A finite element simulation is carried out to extract the elastic properties of the composite as an alternative procedure. Finally, obtained moduli from both methods are validated by comparing them with existing experimental values. Results show a good agreement between the calculated and measured data. It can be concluded that the proposed micromechanical approach can predict weft-knitted composite behavior well without any great effort; however, the finite element analysis gives acceptable results too. The effects of composite variables on the stiffness are investigated and discussed.
