Polymer Composites and Methods of Making the Same
Polymer composites may be made by providing a first polymer material; treating the first polymer material; providing a second polymer material; and pressing the first polymer material and the second polymer material. The polymer composites may be incorporated into ballistic resistant materials and soft armor articles.
High buoyancy composite materials
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 materials which increases the positive buoyancy of the composites in water.
ENERGY DAMPENING SYSTEMS
Energy dampening and/or dispersing systems may include a gel member having a top surface and a bottom surface, an aerated gel member having a top surface and a bottom surface, and the top surface of the aerated gel member secured to the bottom surface of the gel member. In some embodiments, the energy dampening and/or dispersing systems may include a support structure secured to the gel member, and a cover extending over the top surface of the support structure and the bottom surface of the aerated gel member. The energy dampening and/or dispersing systems may be operable in ballistic garments, footwear, sporting goods, and vehicles.
Apparatuses, systems and methods for equipment for protecting the human body by absorbing and dissipating forces imparted to the body
The disclosed apparatus, system and method includes at least a protective garment that prevents concussive effects on internal organs. The garment many include a garment body; and, embedded in the garment body, at least one multi-sectional pad. At least two of the multi-sections may comprise: at least one aramid layer; at least one multi-durometer foam layer having a substantially similar surface area to that provided by the at least one aramid layer; and at least one shield layer.
Multilayer composite material and method for manufacturing
The invention relates to a structural multilayer composite comprising a layer of leather in contact with at least one monolayer comprising parallel aligned fibers and a matrix material. The composite may further comprise film layer(s) that may be breathable and/or waterproof. The structural multilayer composite material is suitable for use in clothing and outdoor gear and apparel.
Ballistic laminate comprising textile elements in which ballistic threads intersect non-ballistic threads
Ballistic laminate for implementing a ballistic structure comprising at least two textile layers placed one on top of the other and joined together. The layers (elements) comprise at least a first textile element, of which the ballistic warp threads, having a count higher than 40 dtex, intersect non-ballistic weft threads, having a count less than 40 dtex, and at least a second textile element, in which non-ballistic warp threads, having a count less than 40 dtex, intersect ballistic weft threads having a count higher than 40 dtex. These at least two elements are joined together using various technologies to obtain a stable structure in which the energy absorption in the face of projectiles is greater than the energy absorption for conventional warp-weft fabrics for the same weight per square meter.
STRUCTURE FOR BALLISTIC PROTECTION OF VEHICLES IN GENERAL AND METHOD FOR THE PRODUCTION THEREOF
Structure for the ballistic protection of vehicles in general, characterized in that it comprises at least a first textile element and at least an additional element formed of a thermoplastic or thermosetting matrix. The structure forms a ballistic system for light armor plating obtained from at least one textile element and one or more thermoplastic or thermosetting base elements. The first textile element includes textile fibers. The second element can include thermoplastic matrices, thermosetting matrices, matrices based on rubber, elastomeric polymers and thermoplastic films of various kinds, the purpose of which consists in providing mechanical properties such that the use of the element can be extended to the field of armor plating while maintaining a high degree of flexibility. The aforesaid elements together contribute to define an efficient ballistic solution while maintaining a relatively low areal density.
Rigid ballistic composites having large denier per filament yarns
A rigid ballistic-resistant composite includes large denier per filament (dpf) yarns. The yarns are held in place by a resin to form a rigid composite panel with improved ballistic performance. The large dpf yarns may be selected from aromatic heterocyclic co-polyamide fibers, polyester-polyarylate fibers, high modulus polypropylene (HMPP) fibers, ultra high molecular weight polyethylene (UHMWPE) fibers, poly(p-phenylene-2,6-benzobisoxazole) (PBO) fibers, poly-diimidazo pyridinylene (dihydroxy) phenylene (PIPD) fibers, carbon fibers, and polyolefin fibers.
ANTI-BALLISTIC BARRIERS AND METHODS OF MANUFACTURE
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. Also, an anti-ballistic protection system for protecting an interior space in a building. The ballistic barrier includes the laminated material having a plurality of layers of lightweight, flexible, ballistic resistant material such as woven sheets which are secured together into the laminate using a adhesive, heat weld, or stitching. The ballistic barrier is configured to be in a compact retracted state which can be deployed to provide a protective state to protect against kinetic ballistic projectiles.
Personal armor resistant to sharp or pointed weaponry
According to exemplary inventive practice, a personal armor system includes a textile-based layer not exceeding ½-half-inch thickness, and an elastomeric coating not exceeding ⅛-inch thickness. The textile-based layer includes a fiber reinforcement and a resin binder. The combined areal density of the textile-based layer and the elastomeric coating does not exceed 2.5 psf. According to a first mode of inventive practice, the elastomeric coating is essentially a strain-rate-sensitivity-hardening elastomer, and the areal density of the textile-based layer does not exceed 2.3 psf. According to a second mode of inventive practice, the elastomeric coating is essentially a microparticle-filled strain-rate-sensitivity-hardening elastomeric matrix material, and the areal density of the textile-based layer does not exceed 1.7 psf. The microparticles (e.g., spherical glass microparticles) do not exceed, by weight, 30 percent of the strain-rate-sensitivity-hardening elastomeric matrix material. The textile-based layer affords ballistic protection; the elastomeric coating affords protection against sharp/pointed objects.
