Applied research of stainless steel fiber-filled acrylonitrile–butadiene–styrene copolymer composites

Composite is prepared by filling acrylonitrile–butadiene–styrene copolymer with stainless steel fiber. Its physical properties and electromagnetic shielding effectiveness are tested. When the mass percent of stainless steel fiber is 15%, shielding effectiveness of composite is 21–59 dB in frequency band of 15 MHz to 3 GHz and cylindrical shell is made of it. Experiments under radiation of X-band high power microwave and ultra-wideband electromagnetic pulse are conducted in microwave anechoic chamber while magnetic fuzes connected with electrical fire head are placed at the center of cylindrical shell. Results show good agreement with test. Coupling effect is analyzed while shell has a hole or slot of millimeter level.
