Abstract: A helmet shell is formed having an outer section of fibrous layers, a middle section of fibrous layers and an inner section of fibrous layers. The outer section layers contain high tenacity abrasive fibers in a resin matrix. The middle section layers contain high strength polyolefin fibers and are in the form of woven or knitted fabrics with a resin matrix. The inner section layers contain high strength polyolefin fibers and are in the form of non-woven fabrics with a resin matrix. The helmet is lightweight and resists penetration of rifle bullets.

Abstract: A method of designing an RPG. A computerized model is created of a shield mesh opening with lines of a net intersecting at nodes and with hard points positioned at least at select nodes. The effectiveness of the mesh opening at a plurality of obliquity angles is determined. In the model, a change is made to the size of the mesh opening and the effectiveness is determined again at a plurality of different obliquity angles. Iterations of this process allow an optimal mesh opening size to be determined for a threat such as an RPG.

Abstract: The disclosed vehicle armor includes a first layer forming an interior bottom surface of the cabin and comprised of a high-strength metal material, a second layer forming an exterior bottom surface of the cabin and comprised of a high-strength metal material, and, a middle layer sandwiched between the first and second layers and comprised of a polymer material. The underbelly device is configured having a plurality of high areas and low areas creating deflection faces and separation distances between an interior of the cabin and an exterior threat. A second, multi-layer composite structure, forming an interior floor of the cabin, may be incorporated as a fragmentation penetration barrier.

Abstract: A composite truss armor and a method of manufacturing the same. The composite truss armor includes a filler material and a three-dimensional (3D) ordered truss structure. The 3D ordered truss structure includes: a plurality of first truss elements defined by a plurality of first self-propagating polymer waveguides and extending along a first direction; a plurality of second truss elements defined by a plurality of second self-propagating polymer waveguides and extending along a second direction; and a plurality of third truss elements defined by a plurality of third self-propagating polymer waveguides and extending along a third direction. The first, second, and third ordered truss elements interpenetrate each other at a plurality of nodes to form a continuous material. The first, second, and third truss elements define an open space. The filler material occupies at least a portion of the open space, and the 3D ordered truss structure is self-supporting.

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.
