Abstract: A cementitious armor panel assembly including cementitious armor panel with ballistic and blast resistant properties attached to a frame structure to produce a protective structure. The cementitious armor panels have a continuous phase resulting from the curing of an aqueous mixture of an inorganic cement binder, an inorganic mineral filler having a particle size of about 150-450 microns, a pozzolanic mineral filler, a polycarboxylate based superplasticizer self-leveling agent, and water. The mixture may also contain alkanolamine, and acid or acid salt. Prior to curing, the continuous phase is reinforced with fiber uniformly distributed in the continuous phase before it is cured to form the panel. The panel may be reinforced with a skin attached to at least one surface of the panel.

Abstract: A system comprising inexpensive composite panels and a configuration that holds them, all components of which are man portable. Select embodiments protect assets against external force and impacts from airborne projectiles. An open box-like stackable frame module holds thin panels along a longitudinal axis of the frame. Multiple frames a reconnected to construct a protective barrier, such as a wall. The panels may be formulated of a very high strength portland cement-based concrete with one side, both sides, or both sides and all edges, covered with elastic material, the combination of which significantly reduces penetration of projectiles. A panel may be covered with specially formulated elastic material comprising multiple layers, each layer of a different type or thickness of elastic material. The elastic material may include reinforcing material such as fabric woven from available COTS high-strength fibers. The panels may be fabricated using basic means available in rural locations.

Abstract: A prophylactic system that reduces or eliminates damage to resources on the side of a structure opposite the side on which a dynamic force is imposed. The system comprises an elastic membrane or sheet, with reinforcement of a toughness tailored to a user's requirements incorporated in the membrane and an adhesive for installation. In one embodiment, the reinforcement is comprised of bundles of fibers aligned in a scrim comprising warp fiber bundles and weft fiber bundles arranged so that fiber bundles are non-parallel to each axes defining the length and the width of the membrane. The fiber bundles are aligned to create spacing between each fiber bundle and an adjacent parallel fiber bundle. An adhesive is used to affix the reinforced membrane to the side of the structure away from the expected force. No protective gear specific to application or use of the adhesive is required to install the system.
