Abstract: A ballistic resistant panel can be configured to be quickly and easily installed in a vehicle door. The ballistic resistant panel can include a plurality of ballistic sheets arranged in a stack. The stack can have an outer perimeter sized to fit within a cavity of the vehicle door. The panel can include a cover disposed over the stack, and the cover can be sealed around a perimeter of the stack to form a waterproof barrier that prevents moisture from reaching and altering the performance of the ballistic sheets. At least one anti-wear strip can be adhered to an outer surface of the cover. The anti-wear strip can provide a low friction surface that protects the panel from damage caused by moving internal door components, such as moving window components that repeatedly rub against the panel.

Abstract: A method of manufacturing a ballistic resistant apparatus with an abrasion-resistant marking can include providing a stack of ballistic resistant sheets within a variable volume container. A top sheet can be placed adjacent to a first surface of the stack within the variable volume container. A sheet of transfer paper, including a printed image formed of sublimation ink containing dye particles, can be placed adjacent to the top sheet, where the printed image is in contact with the top sheet. Gas can be evacuated from the variable volume container, and the top sheet and sheet of transfer paper can be heated to a predetermined temperature for a predetermined duration to achieve dye diffusion thermal transfer of at least a portion of the dye particles from the printed image into the top sheet to form an abrasion-resistant marking in the top sheet.

A system for production of a ballistic resistant apparatus can include a variable volume container configured to receive a stack of ballistic resistant sheets, a vacuum source coupled to the variable volume container to evacuate an amount of gas from inside the variable volume container, a heat source configured to heat the stack of ballistic resistant sheets within the variable volume container, and a pressure source configured to apply pressure to the stack of ballistic resistant sheets within the variable volume container.

Abstract: A flexible ballistic resistant panel can include a first plurality of ballistic sheets comprising high performance fibers, a second plurality of ballistic sheets comprising high performance fibers, and a third plurality of ballistic sheets comprising high performance fibers. The second plurality of ballistic sheets can be adjacent to the first plurality of ballistic sheets, and the third plurality of ballistic sheets can be adjacent to the second plurality of ballistic sheets. Each ballistic sheet within the first plurality of ballistic sheets can be at least partially bonded to at least one adjacent ballistic sheet in the first plurality of ballistic sheets. Similarly, each ballistic sheet within the third plurality of ballistic sheets can be at least partially bonded to at least one adjacent ballistic sheet in the third plurality of ballistic sheets. The first, second, and third pluralities of ballistic sheets can be encased by a waterproof cover.

Abstract: A ballistic resistant apparatus can include a composite layer encasing a ceramic member. The composite layer can include a reinforcing material, such as a woven carbon fiber fabric. The reinforcing material can be impregnated with the matrix material, such as a thermoset resin, which can be cured inside a vacuum bag to form a hard shell that encases the ceramic member and provides a compressive force against an outer surface of the ceramic member. The ballistic resistant apparatus exhibits excellent durability and ballistic performance and is capable of withstanding impacts from multiple rounds of ammunition. In some examples, a plurality of ballistic resistant apparatuses can be arranged in an array and encased by a composite layer to form an array of ballistic resistant apparatuses that can have complex contours or geometries for use in protecting vehicles or dwellings from ballistic threats.

Abstract: A flexible ballistic resistant panel can be constructed with internal adhesive tacking to provide a low cost, high performing panel. The panel can include a first plurality of ballistic sheets, a second plurality of ballistic sheets, and a third plurality of ballistic sheets arranged to form a stack of ballistic sheets. The second plurality of ballistic sheets can include adhesive deposits on a surface of a first ballistic sheet. The adhesive deposits can serve to tack the first ballistic sheet to a second ballistic sheet within the second plurality of ballistic sheets and thereby resist relative movement between the first and second ballistic sheets near the adhesive deposits, similar to a stitch. The adhesive deposits can improve the panel's multi-round capability by constraining damage caused by a first projectile to a location near the first projectile's impact location.

Abstract: A structural ballistic resistant vehicle door can replace an original vehicle door when armoring a vehicle, such as a civilian, military, or law enforcement vehicle. The structural ballistic resistant vehicle door can include a stack of laminated ballistic sheets that include high-performance fibers.

A structural composite layer can encase and protect the laminated stack of ballistic sheets. The structural composite layer can be made of a carbon fiber composite material or a fiberglass composite material.

Abstract: A buffer layer can be used in conjunction with a cutting table to reduce cutting tool wear. During use, a first surface of the buffer layer can rest on a top surface of the cutting table, and a second surface of the buffer layer can receive a material to be cut. The buffer layer can include one or more channels in its second surface, and the one or more channels can correspond to a pattern to be cut from the material. The depth of the one or more channels can be sufficient to provide a clearance depth between a tip of the cutting tool and a bottom surface of each of the one or more channels. The clearance depth can prevent the tip of the cutting tool from wearing against the bottom surface of the channels, thereby increasing life expectancy of the cutting tool and reducing process costs.
