Fabric laminates having superior resistance to penetration of fragments, such as shrapnel. The fabrics are formed of high-strength fibers consolidated with from about 7% to about 15% by weight of an elastomeric matrix composition, and in combination with protective layers of a polymer film on each surface of the fabric. The fabrics achieve a significant improvement in fragment resistance compared to fabrics of the prior art, while also maintaining excellent ballistic resistant properties.

A headgear for use with a mask includes a first strap (660) being configured to engage a back of a patient's head and extend on either side of the patient's parietal bone behind the patient's ears and assume, in use, a substantially circular or oval shape. At least a portion of the first strap is substantially inextensible. The headgear also includes at least one second strap (620, 630) configured to removably connect the first strap to the mask. The second strap may be more extensible than the first strap. At least a portion of the first strap is self-supporting such that the headgear maintains a three dimensional shape when not in use. The substantially inextensible portion of the first strap is constructed to resiliently return to a predetermined shape when not in use. The arcuate region includes a first portion that may be arranged to align substantially parallel with a top of the patient's head and a second portion being arranged to align substantially to a rear surface of the patient's head.

A composite material, the composite material comprising at least one prepreg, said prepreg comprising at least one polymeric resin and at least one fibrous reinforcement; and conducting particles dispersed in the polymeric resin.

A knee protection airbag for protecting the knees of a vehicular occupant. The airbag is inflated from a storage position to a deployed position to substantially fill a space between the knees of the occupant when seated on a front seat and an instrument panel. By filling the space between the knees and the instrument panel, injury to the knees, and other body parts, is prevented. Inflation of the airbag is caused by a determination by a crash sensor system of a pending or actual crash involving the vehicle and may include an anticipatory crash sensor which forecasts a crash between the vehicle and another object prior to impact of the vehicle by the other object. In this manner, the airbag is inflated prior to the crash.

A protective covering is described comprising at least one microporous film attached to a functional layer, the protective covering capable of inhibiting the passage of toxic substances therethrough. Preferably the functional layer is an adsorptive layer contained between two oleophobic, microporous films. Additional shell and backer layers may be added to the construction forming a protective covering having good durability, flexibility and high moisture vapor transmission.

A protection product made of (i) a woven fabric woven with a high-performance fiber, in which the opening rate of thread-opening treatment is 0 to 5%, and the width of a thread constituting the woven fabric is 10-fold or more relative to the thread thickness, (ii) a woven fabric in which the cross-sectional shape of a thread constituting the woven fabric is thinner on an edge side of both ends as compared with an intermediate part in the width direction, or (iii) a woven fabric woven with a twistless high-performance fiber having a fineness of 200 to 15,000 dtex, in which the ratio of the thread width to the thread thickness of at least one of a warp and a weft is 10 to 100, and the opening rate is 0 to 5%.

A protective structure for protecting a body from impact includes an inner layer of relatively flexible material, and which has a plurality of spaced-apart openings extending between opposite faces thereof and a corresponding plurality of protective units. Each protective unit includes a thin-wall, collapsible, fluid-tight enclosure with a volume of fluid filling the enclosure and at least one orifice in an enclosure wall that resistively vents fluid from the enclosure at a selected rate in response to an impact on the structure. The plurality of protective units are received in the plurality of openings so that corresponding first segments of the enclosures projecting form one face of the first layer together form a middle layer. Cooperating surfaces on the inner layer and each protective unit retain each protective unit in the corresponding opening in the inner layer. A method of making the protective units is also disclosed.

An armor composite material has been invented which contains a 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 material in the alternative can be puncture resistant. The invented material offers superior ballistic performance and / or puncture resistance 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.

A unique and novel multi-functional composite fabric and fabrication process for use during chemical, biological, radiological and nuclear countermeasure (CBRNC) events is disclosed. The composite fabric combines the performance characteristics of chemically resistant films and radiation attenuating polymer matrices. The composite fabric offers universal protection against a wide range of military chemical agents, toxic industrial chemicals and materials (TICS and TIMS), biological agents, as well as certain ionizing and non-ionizing forms of radiation. The composite fabric is heat sealable and can be fabricated utilizing hermetically seal seams, and has application in protective clothing and equipment, indoor and outdoor covers, containment systems, bags, drapes, gowns, remains pouches, etc.
