Gel-spun multi-filament polyethylene yarns possessing a high degree of molecular and crystalline order, and to the drawing methods by which they are produced. The drawn yarns are useful in impact absorption and ballistic resistance for body armor, helmets, breast plates, helicopter seats, spall shields, and other applications; composite sports equipment such as kayaks, canoes, bicycles and boats; and in fishing line, sails, ropes, sutures and fabrics.

Molded body armor panels conformed to fit individual torsos based upon gender or, in custom applications, individual features of a particular male or female torso. The individual body panels are constructed of multiple layers of twill or other unconventional long float woven ballistic fibers with each layer impregnated with a curable adhesive. Additional reinforcement may be supplied in appropriate areas, such as breasts, spine, sternum and edges. The multiple impregnated layers of fabric are placed within a mold conforming to the particular torso contour desired. The long floats of the fabric allows the layers to stretch or compress as required to the particular shape desired. The adhesive is cured in the mold under low heat and low pressure, binding the layers of fabric together, as well as binding the conformed yarns of each individual layer in permanent contour. Interior and exterior coverings for comfort and appearance may be supplied.

An armor composite material has been invented which contains a ballistic fabric which has been impregnated with shear thickening fluid. This invention offers a ballistic resistant material that is more flexible and less bulky than comparable, conventional ballistic fabric. The invented material offers superior ballistic performance compared to conventional ballistic fabric-based materials of equal thickness. The invented material can be applied to applications requiring armor that is compact and/or flexible, such as body armor, protective clothing and flexible protective devices and shields, and stab resistant clothing and devices.

Personal body armor has hard armor plates on the front and back of the wearer which extend between a left vest section and a right vest section formed of soft armor. Foam pads are affixed to the interior of the vest sections which space the soft armor and the hard armor plates from the wearer's body and define multiple vertically extending air channels between the wearer and the hard armor plates and the interior of the soft armor. The air channels promote ventilation of the armor and cooling of the wearer. For additional comfort, the soft armor is formed of multiple conventional layers of ballistic material and a {fraction (1/16)} inch molded plastic layer. The hard armor plates are configured to avoid interference with the usual range of motion of the wearer.

Bulletproof vests, body armor, and other tactical vests with quick release buckle mechanisms are described along with methods of their use. The multi-point buckle mechanisms release upon rotating a shaft, allowing the vest panels and straps to fall cleanly to the ground without knocking the wearer off balance. Waist belt clips allow a wearer to put the vest on over his or her head without engaging the emergency release, or the multi-point buckle mechanism can release only the waist straps upon rotating the shaft in the opposite direction. A flap protects the rotatable quick release mechanism from inadvertent activation.

The present invention relates to body armor articles for resisting ballistic objects. The articles comprise woven fabric layers and sheet layers. The woven fabric layers are made from yarns having a tenacity of at least 7.3 grams per dtex and a modulus of at least 100 grams per dtex. The sheet layers comprise nonwoven random oriented fibrous sheets, each of the sheet layers comprising a uniform mixture of 3 to 60 weight percent polymeric binder and 40 to 97 weight percent non-fibrillated fibers. The woven fabric layers and the sheet layers are stacked together comprising a first core section which includes at least two repeating units of, in order, at least one of the woven fabric layers then at least one of the sheet layers. The sheet layers comprise 0.5 to 30 wt % of the total weight of the article.

The present plate carrier includes front and rear panel sections with internal pockets for supporting ballistic plates and inserts, but positions the rear panel section to provide improved thoracic protection. The front and rear panel sections are suspended by shoulder straps, which connect to the rear panel section at a mid point below the top edge of the rear panel section. The mid point connection of the shoulder straps causes the rear panel section to ride higher than the front panel section and higher on the wearer's back thereby positioning the ballistic plate inside high on the wearer's back and providing better ballistic coverage of the wearer's upper thoracic area. One of the internal pockets of each panel section has facing strips of hook and loop material sewn around its inner periphery that adhere together around a ballistic plate to center and hold the plate in place within the pocket.

An article of clothing, body armor or garment having at least one limb-receiving sleeve includes a housing secured in encircling relation to the sleeve. A self-sustaining tourniquet is disposed within the housing. An opening is formed in the housing and a cover is provided to close the opening. The tourniquet is positioned fully within the housing when the cover is closed. The tourniquet is oriented in the housing so that a free end of the tourniquet is in registration with the opening. A handle is secured to the free end and is adapted to be grasped by a user when the cover is open. The diameter of the tourniquet is reduced when the handle is pulled upon. A ratchet and pawl structure prevents the tourniquet from loosening after the handle has been pulled.

A modular and field adaptable body armor system includes a plurality of flexible, air-permeable, thermally vented plates arranged in fixed relationships that pro-vide flexible, modular, field-adaptable protection for the torso and extremities without excessive weight or heat bur-den. The TVA plates include protective cards suspended in a parallel, louvered relationship between inner and outer mesh layers, thereby permitting air to flow therebetween while providing a flexible, compressible, modular barrier that protects the torso and extremities against projectiles. In embodiments, the outer mesh layer resists penetration and compresses cards together to intercept a projectile that would otherwise pass therebetween. Protective cards can include thermally pressed and flexed laminated UHMWPE. TVA panels can be removed and exchanged in the field according to the requirements of each mission. In embodiments, the TVA plates are laced together and/or attached to an underlying fabric carrier garment.

The present plate carrier includes front and rear panel sections with internal pockets for supporting ballistic plates and inserts, but positions the rear panel section to provide improved thoracic protection. The front and rear panel sections are suspended by shoulder straps, which connect to the rear panel section at a mid point below the top edge of the rear panel section. The mid point connection of the shoulder straps causes the rear panel section to ride higher than the front panel section and higher on the wearer's back thereby positioning the ballistic plate inside high on the wearer's back and providing better ballistic coverage of the wearer's upper thoracic area. One of the internal pockets of each panel section has facing strips of hook and loop material sewn around its inner periphery that adhere together around a ballistic plate to center and hold the plate in place within the pocket. The plate carrier has removable side plate pockets mounted to a detachable cummerbund by hook and loop fasteners allowing the ballistic plates to be properly positioned on the cummerbund.

A system for providing streaming air to evaporate perspiration from a wearer of personal armour. The system incorporates a set of voluminous layers for wearing beneath the armour, one of which is enveloped voluminous layer. The envelope is perforated in the direction of said wearer, such that an air blower forces air into the perforation and thence onto the body of the wearer.
