Pant Government Engineering College, New Delhi 110020, India article info Article history: Received 17 November 2019 Received in revised form 30 December 2019 Accepted 1 January 2020 Available online xxxx Keywords: Reinforcement Matrix Woven Plain Twill Hybrid fabric Textile composites Python script abstract The prediction of the mechanical strength of composites must be known before use or fabrication. The computerized modeling and analysis helps in prediction of the realistic performance of the composite products. The current research work presents the modeling routs of yarns, yarn interpolation for path, cross-section, and orientations with finite element analysis of woven fabric reinforcements. The geomet- rical modeling routes of textile woven reinforcements at meso-scale described by using TexGen 3.10, which is a python scripted software package, developed by the polymer composites group at the University of Nottingham, UK, works as a preprocessor for characterization of textile reinforcements. The finite element analysis of textile woven reinforcements is done by using a commercially available software package ABAQUS 6.14-5. Due to the similarity of python scripted codes in both the software’s, ABAQUS is considered as an analysis tool for textile reinforcements among the so many FE based plat- forms. Textile woven fabric unit cell having plain and twill weaving patterns are explained with Kevlar (monolithic) and Carbon-Kevlar (hybrid) yarns with finite element compression behaviour analysis, and discussed to understand the mechanical performance of polymer textile composites.

Introduction Composites are used worldwide due to their extreme advan- tages over the individual material as high strength/stiffness to weight ratio, corrosion resistance, high durability, high flexural modulus to carry demanding loads, high impact strength, chemical resistance, toughness and design flexibility etc. High strength advanced polymer textile composites having their advantages in various areas like automobile, military, space aircraft, etc. [1]. Com- posites are made by two different phase materials, namely rein- forcement and matrix, which are not soluble to each other. Reinforcement plays a vital role in the mechanical and structural performance of composites, as it carries and uniformly distributes the whole load, applied on the matrix. The strength of the rein- forcement is much greater than strength of matrix but the strength of matrix affects many mechanical properties. The cross-section, orientation, material, tow size, fiber type of the reinforcement material plays a significant role in the mechanical performance of composites. The fiber may be synthetic (carbon, kevlar, glass etc.) or natural fiber (flax, hemp, jute, kenaf, sisal etc.) and matrix may be thermo- plastic (polyamide, polypropylene, neoprene, teflon, bakelite, acrylic, acrylonitrile butadiene styrene, nylon, polybenzimidazole, polycarbonate, polystyrene, polyvinyl chloride etc.) or thermoset- ting matrix (epoxy, polyester, vinylesters, polyimide, phenolic resins, amino resins etc.). There are so many methods available for the manufacturing of polymer matrix composites such as hand lay-up, spray lay-up, RTM, VARTM, compression, injection molding, pultrusion, auto- clave, filament winding, etc. The textile composite manufacturing hierarchy (Fig. 1) defines the stages of modeling of a composite product from fiber. The virtual modeling and analysis using some software tool approach are helpful in the prediction of realistic per- formance of a composite product. The prediction of realistic perfor- mance of textile and textile composite products depends on the accuracy of modeling and post-processing analysis approach used.
