Abstract
A method for stacking fibers less than 10 mm long into a cartridge case, including an impregnation stage for fibers arrayed into at least one skein together with a solidifiable material, the skein being solidifiable inside a mold and then, in the solidified state, being cut into at least two slices each of a thickness which is the desired fiber length. Such cartridges are for use as screens or decoys against radar or other detection or guidance systems.
Claims19
A method for stacking short fibers less than 10 mm long into a cartridge, the method comprising:
- arranging at least one array of long fibers in at least one skein, impregnating the skein with a material that can solidify at a first temperature, placing the skein so impregnated into a mold, solidifying the skein in the mold by changing the temperature of the mold to a first temperature, cutting the skein in solidified state into at least two solidified slices, each slice being of a that is a desired length of the short fibers, and eliminating the solidifiable material by changing the temperature of the slices to a second temperature.
