In several applications, the industrial and protective fabrics might be subjected to punching by the rigid sharp spikes. Fabric resistance to the penetration of the puncher at a constant rate was studied. The analysis of the factors influencing the resistance of the fabric and an explanation of the puncture mechanism were generated. Punching force-displacement curves were obtained and four noticeable fabric failure modes were observed. A special setup was designed so that the fabric sample can be subjected to the biaxial stresses during the puncture tests. This paper studies the puncture behaviors of the plain, twill 1/3, and twill 2/2 woven fabric designs. It was found that the increase in the number of fabric layers from one to three and the number of picks/cm from 17.6 to 27.2 would elevate the punching resistance and the punching energy by 354% and 333%, respectively, with the insignificant change in the values of specific punching force and energy. Plain weave design proved to have higher values than twill design. A high correlation was observed between fabric tensile strength, fabric Young’s modulus, fabric failure energy and its punching force and punching energy.

冲压力作用下机织物的行为分析

在几种应用中,工业和保护性织物可能会受到坚硬的尖刺刺穿。研究了织物对打孔机以恒定速率渗透的抵抗力。分析了影响织物抗力的因素并解释了穿刺机理。获得了冲孔力-位移曲线,并观察到四种明显的织物破坏模式。设计了一种特殊的设置,使织物样品在穿刺测试期间可以承受双轴应力。本文研究了平纹,斜纹1/3和斜纹2/2机织织物的刺穿性能。结果发现,织物层数从一增加到三,纬纱每厘米的数量从17.6增加到27。图2的曲线将使抗冲孔能力和冲孔能量分别提高354%和333%,而比冲孔力和能量值的变化很小。平纹设计证明比斜纹设计具有更高的价值。观察到织物的拉伸强度,织物的杨氏模量,织物的破坏能与其冲孔力和冲孔能量之间具有高度相关性。
