According to an embodiment of the present invention, a three-dimensional architected armor structure includes a core structure and a matrix. The core structure includes: a plurality of impact members; a plurality of joint members below the impact members; and a plurality of connection members respectively extending between one of the impact members and one of the joint members. The matrix fills at least a portion of a space between the impact members, the joint members, and the connection members.

A composite structure for stab protection includes layers of flat structures placed on top of each other, and an embedding material, wherein, in at least some of the layers placed on top of each other, the flat structures of adjacent layers are offset relative to one another, the flat structures of the composite structure are at least partially embedded in the embedding material, and the composite structure includes separated connecting elements, wherein before they are separated, the separated connecting elements have connected at least some of the flat structures of adjacent layers with one another.

A system and method for an armor system for protecting the groin. While the system is useful for either gender, it is particularly valuable to protect male genitalia which are particularly vulnerable to damage. The system utilizes at least one, and commonly two, armor components. One armor component is a specifically designed armor plate of the type and construction common to plates in plate carriers that is generally worn external to the pants. While the plate or over armor can be used alone, in an embodiment of the system, the plate is worn over a high impact ballistic cup which is inside the pants. The cup is designed to absorb impact from the over armor against the body to further protect the groin area.

Methods of making improved framed transparent armor product are provided. The product having a compressive element; a high flow adhesive-sealant elastomeric material; a frame and a multilayer transparent armor (TA) laminate. The frame and TA laminate being about the same depth, the frame being larger than the TA in length and width thereby defining a potting gap between the interior of the frame and the outer edges of the TA when the TA is placed inside the frame. The compressive element is located with the potting gap at the site of any layer of the TA that may undergo expansion.

A ceramic composite can include a first ceramic phase and a second ceramic phase. The first ceramic phase can include a silicon carbide. The second phase can include a boron carbide. In an embodiment, the silicon carbide in the first ceramic phase can have a grain size in a range of 0.8 to 200 microns. The first phase, the second phase, or both can further include a carbon. In another embodiment, at least one of the first ceramic phase and the second ceramic phase can have a median minimum width of at least 5 microns.

A ballistic panel formed with a ballistic material, the panel comprising: a panel with a filled void; wherein the filled void is filled with a ballistic replacement material; and wherein the filled void exhibits ballistic properties equivalent to the ballistic panel formed with the ballistic material; wherein the ballistic replacement material and the ballistic material comprise between about 1121 kg/cubic meter (about 70 pounds per cubic foot) and about 1442 kg/cubic meter (about 90 pounds per cubic foot); and wherein the ballistic replacement material and the ballistic material comprise: about 1 part by mass Portland cement; about 0.5 to 1.5 part by mass fine aggregate; and about 0.0005 to 0.05 part by mass air entrainment additive; about 0.005 to 0.15 part by mass fiber; about 0.005 to 0.05 part by mass aluminum hydroxide and about 0.005 to 0.05 part by mass calcium phosphate.

A method for retrofitting a preexisting wall to include bullet resistance. The retrofitted wall incorporates ballistic paver blocks that are capable of augmenting either an interior or exterior wall. The flexibility gained by using ballistic paver blocks affords cost and weight savings over traditional concrete, or alternatively, metal shielding.

In a first aspect, the invention provides a sensorially attractive puncture-resistant panel having a first surface and a second surface, wherein at least one of the first surface and the second surface is sensorially attractive. In some embodiments, the panel comprises, consists, or consists essentially of a first layer having a first surface and a second surface, wherein at least one of the first surface and the second surface is sensorially attractive, and a second layer that is puncture-resistant and comprises, consists, or consists essentially of a puncture-resistant material. In some embodiments, the panel is sensorially attractive to a child.
