Paper Abstract

In view of the practical demand of infrared (IR) / millimeter wave (MMW) composite interference smoke technology, the extinction mechanism of chopped carbon fiber (CF) to IR and MMW was analyzed, and the chopped CF smoke cloud was formed by explosive dispersion. Taking attenuation rate and effective time as indexes, the IR/MMW composite interference performance was studied experimentally. The results show that the chopped CF has the ability to attenuate IR/MMW, the attenuation is the result of both absorption and scattering, and the smoke cloud of chopped CF has good attenuation effect on IR, 3mm and 8mm waves. The attenuation rate is more than 95%, and the effective time is 45s, 67s and 54s, respectively, indicating that chopped CF is a good smoke material with IR/MMW interference function.
