摘要
碳纤维发热体替代金属发热体是一种必然的趋势。研究了碳纤维发热线在空气中工作时的温度、时间、电压、电流的变化规律,进行了不同规格、长度、电压的升温试验,拟合温升曲线得到了温度变化与时间的数学关系式。研究结果表明:碳纤维发热线在空气中工作时最高温度和长度成反比、和电压成正比。其研究成果将为碳纤维的应用提供工程参考。
It is an inexorable trend that carbon fiber heater replaces metal heater.In this paper,the temperature,time,voltage and current of carbon fibre heating wire working in air are studied.The temperature rise tests of different specifications,lengths and voltages are carried out.The temperature rise curve is fitted and the mathematical relationship between temperature change and time is obtained.The results show that the maximum temperature and length of carbon fibre heating wire in air are inversely proportional to the voltage.The research results will pro.vide engineering reference for the application of carbon fibers.
