摘　　要：研究碳纤维纱线及其织物的电阻对温度的响应。通过实验发现碳纤维纱线的电阻随着温度的增加而线性减小,碳纤维织物的电阻也随着温度的增加而减小,且在一定的温度范围内其变化呈线性关系。制备的经编结构碳纤维织物电阻对温度响应的灵敏度有较大提高,表明织物的结构有助于增加碳纤维织物电阻对温度响应的灵敏度。织物电阻随温度变化的机理主要是由在温度变化的过程中纱线间的接触电阻变化引起的。In this paper, the resistance response of CF yarn and its textile structure to temperature are studied. It was found that the resistance of CF yarn has a negative linear relationship with increasing temperature, and that of CF yarn fabric has a negative linear relationship with increasing temperature. The sensitivity of the resistance of warp-knit fabric structure made by CF responding for the temperature has been improved greatly, which indicated that the textile structure is useful to increase the sensitivity and accuracy of the temperature sensing. The main mechanism of the fabric sensing has been deduced to be the change of the contact resistance between yarns during temperature changing.
