Abstract

Fly-ash cenosphere particles were used as mixture in aluminum matrix composite by squeeze casting method [1]. The electromagnetic interfering shielding effectiveness (EMISE) was investigated in the frequency range from 0.03 MHz to 1.5 GHz. It showed the SE value of Al2024/cenospheres composite (ACC) is higher than that of aluminum alloy, and comparative to traditional material 1J50. Unlike 1J50, the mechanism of EMI shielding for ACC is reflection and multiple reflections. Analyzed by XRD and SEM, chemical reactions may occur between the matrix and cenosphere particles during the casting procedure, but it affects the shielding effectiveness little.
