Abstract: The simulation design of low frequency electromagnetic shielding coating material for carbon fiber reinforced composites was carried out by using CST EM Studio electromagnetic simulation software. The analysis model of shielding effectiveness of low frequency electromagnetic field was established. The influences of permeability, conductivity and coating thickness on shielding effectiveness were studied. The results showed that the shielding effectiveness of electromagnetic shielding coatings for carbon fiber reinforced composites increased with the increase of permeability, conductivity and thickness in low frequency band.
