HEMP shielding performance on carbon fiber composite power supply cabinet

  Objectives  Regarding demands for the lightweight and high-altitude electromagnetic pulse (HEMP) protection properties of carrier-borne cabinets, through the oven process, a carbon fiber composite cabinet is constructed.

  Methods  CST Studio is used to simulate and evaluate the protective performance of a composite chassis. Nickel-coated carbon fiber and metal foil are selected as electromagnetic reinforced materials on the basis of the carbon fiber composite structural design and electric connection design of interlamination and gap electromagnetic reinforcement. HEMP protection performance is tested by using bounded wave simulator.

  Results  The results show that the HEMP shielding efficiency is above 65 dB.

  Conclusions  The carbon fiber composite cabinet has lightweight, high-strength, HEMP shielding and anti-severe environment properties, giving it significant project value and application prospects.
