EDDY CURRENT EFFECT OF IRON POWDER/EPOXY COMPOSITE AND ITS DEICING/ANTI ICING PERFORMANCE

Abstract

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.
