A multilayer composite includes adjacent filler layers having a filler material dispersed within a first polymeric matrix and an intervening-layer disposed between the adjacent filler layers. The intervening-layer comprises nanoplatelets embedded within a second polymeric matrix and are aligned substantially parallel to the adjacent filler layers. The intervening-layer is configured to fail upon application of a force to the multilayer composite that is greater than or equal to a predetermined force threshold.

The invention relates to a composite sheet, and a ballistic resistant article, comprising unidirectionally aligned high performance polyethylene (HPPE) fibers and a polymeric resin, wherein said polymeric resin comprises a homopolymer or copolymer of ethylene and wherein said polymeric resin has a density as measured according to ISO1183 of between 930 and 980 kg/m3, and a peak melting temperature of from 115 to 140° C.; and said polymeric resin is present in an amount of from 5 to 25% by weight based on the total weight of the composite sheet. It further relates to a method for manufacturing a composite sheet comprising assembling HPPE fibers to a sheet, applying an aqueous suspension of a polymeric resin to the HPPE fibers, partially drying the aqueous suspension, optionally applying a temperature and/or a pressure treatment to the composite sheet.

Ballistic resistant composite materials having high positive buoyancy in water are provided. More particularly, provided are foam-free, buoyant composite materials fabricated using dry processing techniques. The materials comprise fibrous plies that are partially coated with a particulate binder that is thermopressed to transform a portion of the binder into raised, discontinuous patches bonded to fiber/tape surfaces, while another portion of the particulate binder remains on the fibers/tapes as unmelted particles. The presence of the unmelted binder particles maintains empty spaces within the composite to materials which increases the positive buoyancy of the composites in water.

Laminates and their process of manufacture, with the laminates made with anti-ballistic materials, such as woven and unwoven fabrics. The laminates are provided with different structures, materials, bondings, and other features, and example methods of manufacturing those laminates efficiently and in mass quantities. The method of production is a process of laminating individual flexible sheets including anti-ballistic material (which may be of woven or unwoven cloth or thin solid sheets or foils comprised of one or more light-weight anti-ballistic materials) into a flexible laminate for use to protect people or spaces from ballistic objects such as bullets and shrapnel from weapons and other moderate to high-kinetic energy objects

A personal protective vest assembly is described herein. The personal protective vest assembly includes a personal protective vest and a body armor panel positioned within the personal protective vest. The body armor panel includes a ballistic material panel assembly that includes a plurality of layered material segments defined between a strike face and a wear face. Each of the layered material segments includes a different ballistic material.

Bladders/containers designed to hold a meaningful amount of material (in any state: solid, liquid or gas) to conductively absorb heat from the human body. In addition, the material may be consumed by the user wearing the bladder/container, thus providing a source of hydration for the user. The bladders/containers would also enhance impact and/or ballistic protection of the user.

The disclosure relates to sintered ceramic grains comprising 3-55 wt. % alumina, 40-95 wt. % zirconia and 1-30 wt. % of one or more other inorganic components. The invention further relates to a method for preparing ceramic grains according to the invention, comprising: making a slurry comprising alumina, zirconia; making droplets of the slurry; introducing the droplets in a liquid gelling-reaction medium wherein the droplets are gellified; drying the gellified deformed droplets.

A multi-plate armor system used as an add-on armor in the armored vehicles, especially military vehicles. More specifically, disclosed is an armor system which, having a structure that will not be affected from impacts as well as having weight values acceptable for industry standards per unit area (kg/m.sup.2), at least two plates positioned to the armored vehicle body with a specific distance between them, allows the resulting destructive effect to be felt in the large surface with minimal damage by deflecting the impact direction of the ballistic threat such as bullets, spall etc.
