中文摘要：
用不锈钢纤维和碳纤维编织成一种经编纺织结构，在轴向拉伸过程中分别测试两种织物的应变和电阻。实验表明：织物的电阻随应变的增加而减小，随应变的恢复而增大，呈一定的函数关系，其中碳纤维织物在拉伸恢复循环内和多次拉伸恢复循环间的重演性比不锈钢纤维织物好。经过纱线间表面摩擦系数的测定及表面形貌的观察，碳纤维纱表面相对较光滑、表面摩擦因数小，织物拉伸恢复时塑性变形小，因此碳纤维织物电阻对应变响应的重演性要优于不锈钢纤维纱。
英文摘要：
A warp-knit fabric structure is made by stainless steel fiber or carbon fiber. The fabric resistance and strain are measured by Universal Material Tester and Agilent 34401A digital multimeter. It is observed that the resistance of the fabric decreases with the increase of the strain, and shows a definite function relationship. The repetition of the carbon fiber fabric responding for the resistance to strain is better than that of stainless steel fabric between elongation and recovery stages during one testing cycle and different cycles. It is also observed that the surface of the carbon fiber is more slippery than the stainless steel fiber by SEM, meanwhile the friction between carbon fiber yarns is lower than that of the stainless steel fiber yarns. So the strain sensing repetition of the carbon fiber fabric is better than that of the stainless steel fiber fabric.
