Electromagnetic pulse shielding effectiveness of the conductive composites equipment compartment

In this paper, the lightweight equipment compartment of full composites which has anti-electromagnetic pulse effectiveness is made using the nickeled-carbon fiber composites skin which uses nickeled-carbon fiber as basic materials, glass fiber composites skin, polyurethane foam and other fittings. In the meantime, the effectiveness of the equipment compartment under HEMP and LEMP is studied. The testing results show that the HEMP shielding effectiveness can achieve 50.1 dB when its rising time is 2.8 ns and half pulse width of the pulse wave is 24 ns; the HEMP shielding effectiveness can achieve 57.2 dB when its rising time is 3.2 s and half pulse width of the pulse wave is 40.3 s.
