Research on Shear Performance of Tackified Woven Fabrics
Based on the modified experiments for picture frame, the in-plain shear property of the tackified fabric is investigated. The results show that the behavior of tackified woven fabrics are similar to those of the fabric. According to the testing results, the shear properties of tackified fabrics are analyzed from the concentration of tackifier. In addition, the shear model of tackified woven fabric is built. The shear process is devided into three stages, at the initial stage, the shear force is small, and it cant overcome the friction at the cross point. Therefore, the change of shear angle has been reflected through rotor angle. At the shear stage, the bending yarn could be supposed of beam, and the normal pressure and friction are derived. At the compression stage, the value of force is indicated by the change of width of fiber bundle. At last, the shear performance is reflected by moment equilibrium.The results show that the model can predict the shear performance of the tackified fabric well.
