摘要:
A spike resistant package containing a pouch, a first grouping of spike resistant textile layers, and a slip layer. Each of the textile layers within the first grouping of textile layers contains a plurality of interwoven yarns or fibers having a tenacity of about 5 or more grams per denier. At least a portion of the spike resistant textile layers comprise about 10 wt. % or less, based on the total weight of the spike resistant textile layer, of a coating comprising a plurality of particles having a diameter of about 20 μm or less on at least one of the surfaces of the spike resistant textile layer. The slip layer has a stiffness of less than about 0.01 N-m and a static coefficient of friction (COF) between the slip layer and the second side of the first grouping of less than about 0.40. The pouch encapsulates the grouping of textile layers and slip layer. An article containing the package is also described.

Embodiments of the present invention relate to composite materials. In one embodiment, a composite material comprises an inorganic ceramic matrix comprising a first surface and a second surface opposite the first outer surface and generally parallel to the first outer surface. At least one open weave fiber glass fabric is disposed in the inorganic ceramic matrix between the first surface and the second surface. In another embodiment, a composite material comprises a first inorganic ceramic matrix comprising pieces of stone, a second inorganic ceramic matrix attached adjacent to the first inorganic ceramic matrix, and at least one open weave fiber glass fabric disposed in the second inorganic ceramic matrix.

The present invention discloses a method of producing and application for a projectile resistant matrix that allows for manufacture of low weight projectile resistant armor trauma shields without metal or ceramic plates using projectile resistant textiles encapsulated in a composite matrix through use of injection molding process or spray-on technique as constituents of the projectile resistant trauma shield without metal or ceramic plates of the present invention.

This invention relates to the use of an open, plain Leno Aramid fiber weave wrapped around the armor base plate in such a fashion that the wrap on the strike face surface is bonded with a thermoset resin while the continuous fibers around the back are left resin-free and able to distort, allowing localized deformation while keeping the remainder of the “wrap” holding tight. This wrap technique keeps the composite backing tight to the strike surface while allowing all of the benefits of localized fiber movement and tensile failure on the backside of the target. Other high performance fibers, such as fiberglass, also woven in a Leno weave and applied in the same method will yield similar results. This invention also relates to the placement of a “slip layer” between the fiber surface and the polymer coating of an armor system. This layer, consists of Teflon, silicone, or other low friction, bonding resistant materials, and prevents intimate bonding of the polymer coating to the fiber back and allows a low friction slip surface that isolates the polymer from the trauma of fiber deformation and breakage.

摘要:
The multi-layered ballistics armor includes one or more containment layers covering at least a portion of an impact absorbing layer formed of a fragmenting material to minimize and contain fragmentation of the impact absorbing layer. The one or more containment layers may include one or more primary containment envelopes, and the fragmenting material may be a ceramic such as silicon carbide, carbon/carbon composites, carbon/carbon/silicon carbide composites, boron carbide, aluminum oxide, silicon carbide particulate/aluminum metal matrix composites, or combinations thereof. The multi-layered armor may include one or more adhesive layers over the impact absorbing layer, one or more composite backing layers, an energy absorbing layer, and a flame resistant layer. A secondary containment envelope can be provided over the one or more primary containment envelopes, composite backing layers, and energy absorbing layer.
