Abstract

In order to deal with the military threat of MMW detection and precision-guided weapons, Millimeter-wave interference property of Carbon Fiber(CF) and Military Expanded Graphite(EG) is analyzed contrastively. The experimental results show that under the same index condition, the attenuation rates of Military Expanded Graphite jamming 3mm and 8mm wave are 68.86% and 61.24%, the mass extinction coefficient (Mc) of 3mm wave is 0.193m² /g and the Mc of 8mm wave is 0.149m² /g. While, the attenuation rates of CF jamming 3mm and 8mm wave are 96.80% and 94.65%, the CF mass extinction coefficients of 3mm and 8mm wave are 0.618m² /g and 0.515m²/g. The evaluations of attenuation rate and mass extinction coefficient show that the interference effects of short-cut CF on 3mm and 8mm wave are obviously better than Military Expanded Graphite, and the attenuation ability of 3mm wave is stronger than 8mm wave. The compound enhancement technique of Carbon Fiber and Expanded Graphite is studied. The research shows that mixing of Carbon Fiber with Expanded Graphite can obviously enhance the MMW interference property of Expanded Graphite smoke screen. And the dispersion characteristic of Carbon Fiber is improved. Research results provide a new way of idea and technical methods for the study of new MMW smoke agent, enrich the application of the multi-wave smoking vehicle, and enhance potential military effectiveness of CF in the field of passive jamming.
