“…The warp yarn has a tendency to pull off the weft yarn at the point of the interlacement along its length as illustrated in Figure 6(a). Accordingly, the pulling force is determined by the yarn-to-yarn friction over and under the crossing areas in the fabric structure [42,43]. Subsequently, the value of the friction force between the warp and weft yarns depends on the magnitude of the forces on both sets of the yarns and is influenced by the value of tension force acting on the yarns.…”

2D fabrics are used widely and to good effect as a reinforcement for many planer composites and simple curved structures, i.e. a cylindrical arc. There are, however, manufacturing difficulties in the formation of composite structures which are curved across two axes, i.e. a bowl shape. This can be addressed by manufacturing “3D” fabric preforms; however, this requires complex machinery and is slow and expensive. It is, therefore, desirable to form complex curved shapes from planer textile structures; this is either done by cutting a net shape from the textile and placing it on a mold or by using force to stretch the fabric to the mold. These methods, however, result in discontinuous reinforcement or poor distribution of phases, respectively. Wrinkling of the fabric during formation will increase the possibility of composite failure under loading because of the presence of rich fiber or resin areas. A new method was suggested to manufacture 3D shapes from 2D fabric through the application of cyclic loading on the 2D fabric under a continuous hot air till the final fabric prepreg bagging form is reached. The composite fabrication process was completed in two steps: imposing dynamic bagging of the chemically treated 2D Jute fabric with 16% sodium hydroxide in slack form to fit the die final shape prior to the infusing of the resin accompanied by pressing two halves of the mold. A proto-type setup was designed to study the two-step fabrication method for various shapes of 3D fabric reinforcement.

“…There are three main methods to test the In-plane shear properties of fabrics: picture frame, BE and yarn pullout method. Yarn pullout method [20][21][22] is a relatively new test method, which has achieved good results in testing the shear properties of 2D para-aramid fabric. BE is an effective test method to measure the in-plane shear properties of 3D fabric reinforcements.…”

In‐plane shear behaviors of unbalanced 3D interlock woven reinforcement in bias extension test: Experiments and finite element modeling

et al. 2021

In this paper, the in-plane shear deformation of unbalanced 3D interlock woven reinforcement (IWR) was investigated through experiments and finite element modeling. Five specimens with five layers warp (six layers weft) were designed and prepared. The warp is 792 tex carbon tows and weft is 396 tex carbon tows. This kind of reinforcement is unbalanced because that the linear density of warp is different from that of weft. The in-plane shear deformation of unbalanced 3D IWR was tested by bias extension test. The bias extension process was simulated by finite element method from macro and meso scales.The results of simulation are basically consistent with experiments. The bias extension process can be divided into three stages: Meso scale deformation stage, multiscale deformation stage and Reinforcement failure stage. At meso scale deformation stage, the tensile load and shear angle are small when the displacement is less than 7.5 mm. There is no obvious change in the macro scale, while the weft slipping in the meso scale mainly occurs in area B. The deformation of B1 and B2 are asymmetric because the linear density of warp is different from that of weft. In the multiscale deformation stage, asymmetric deformation at the macro scale begins to appear when the displacement is between 7.5 mm and 20 mm. There is obvious in-plane shear deformation in area C at the meso scale. In the reinforcement failure stage, A large number of weft yarns are pulled out from the reinforcement in area B.

This paper reviews the topic of yarn pull-out on a plain woven fabric. It deals with previous works on experimental testing and theory exploration regarding this process, also including the prominent stick-slip behavior and the associated modeling techniques. Finally, it discusses the advances in chemical treatment and construction modification for the increase in yarn gripping force. The current paper serves as a source of literature for those willing to undertake additional research in this area and for those interested in developing flexible body armor with improved ballistic protection.
