Abstract
A variety of fibers of different materials, lengths and diameters have been studied regarding dissemination efficiency and screening characteristics. Fibers were disseminated using a small charge of high explosive. Laboratory measurements were performed in a 326-cubic m aerosol chamber. Transmission and mass concentration measurements were recorded simultaneously over a period of 360 s. The wavelengths and wavebands studied were: 0.6328 mu m, 1.06 mu m, 3-5 mu m and 8.13 mu m. Several dissemination problems had to be solved; for example, some fibers had to be preheated to remove a glue coating. All fibers tested to date in the laboratory have shown to be poor attenuators in the visible and infrared regions of the electromagnetic spectrum, when compared to similar masses of more traditional obscurants. The metallic fibers, since they were more easily dispersed, showed higher attenuation than non-metallic fibers. TRUNCATED
