Study the Effect Of Increasing the Mechanical Strength of Epoxy Composites Reinforced with Iron Powder on the Dielectric Strength of the Insulator and Their Thermal Conductivity

Iron powder (Fe) was added to epoxy polymer with a weight percentage of 1% and for particle size <60µm, It was added after being roasted at a temperature of 300 C°, Iron-reinforced samples, and pure samples were formed by manual molding method at a temperature of 80 C° to be compatible with the test devices. The thermal conductivity and breakdown voltage of these insulators were measured after increasing the mechanical strength and comparison between them.
