摘要/Abstract

摘要： 常温下将微米级铁粉导磁材料添加到环氧树脂基体中固化,获得铁粉/环氧树脂复合材料,采用扫描电子显微镜(SEM)对样品的结构微观形貌进行分析;采用热重分析仪(TGA)以及红外成像仪对样品进行热稳定性分析;自制电磁感应加热器对样品进行电磁感应实验,测试样品的升温能力以及除冰能力。结构微观形貌分析表明样品内部Fe粉颗粒分散均匀,粒度在0.5 um~4 um之间。热稳定性分析表明样品从24 ℃到200 ℃之间质量损失只有1%,表明样品热稳定性良好。电磁感应实验结果表明Fe粉含量和电路输入功率分别通过影响材料的导磁率、导电性能和感应电流来影响样品的感应电动势,最终影响样品的表面温度。Fe/Ep-100%样品有最大的平均升温速率与除冰速率,分别为1.1×10^-1℃/s和1.2×10^-2 g/s。

Abstract: Iron/epoxy resin composites were prepared by adding micron-sized iron powder to epoxy resin matrix at room temperature. The microstructure and morphology of the samples were analyzed by scanning electron microscopy (SEM). Thermogravimetric analyzer (TGA) and infrared imager were used to analyze the thermal stability of the samples. The self-made electromagnetic heater is used to test the heating capacity and deicing capacity of the sample. Microstructure and morphology analysis showed that Fe powder particles were uniformly dispersed in the sample, and the particle size was between 0.5 um and 4 um. Thermal stability analysis showed that the mass loss of the sample was only 1% from 24 ℃ to 200 ℃, indicating good thermal stability. The results of electromagnetic induction experiment show that the content of Fe powder and the input power of the circuit affect the electrical conductivity and magnetic permeability of the sample and induce current to change induced EMF, and finally affect the surface temperature of the sample. The maximum average heating rate and deicing rate of Fe/Ep-100% samples were 1.1×10^-1 ℃/s and 1.2×10^-2 g/s, respectively.
