Results are presented on a 9-month evaluation program on resistance to penetration of a highly dilatant fluid by 30-caliber ball and AP bullets. Military ammunition of both types was fired point blank into test cells containing the fluid packaged according to these general concepts 1 flexible, 2 semi-flexible, 3 conformable rigid, and 4 rigid. The principal objective was to find a fully-flexible system that could use the unusual self-healing capability of the material. Degrees of effectiveness of the various packaging systems for confining the fluid are described in this report. Packaging materials that were tested included commercial fiberglass, high tensile strength plastic, and aluminum honeycomb materials. Cell reinforcements studied included reticulated foam and various grades of screen wire mesh. In an effort to improve shear and short-range tensile strengths of the dilatant fluid, asbestos, metal, and ceramic fiber additives were evaluated.
