A seal-healing material that is used to form fuel tanks and other fuel containing items uses a pair of reagents disposed within multiple individual cells on either side of a polymer film with other polymer films forming the outer boundaries of each set of cells. The reagents, when mixed, chemically react to form a sealant. An elastomeric sheet is bound to each polymer film such that a fibrous material is disposed between each polymeric film and elastomeric film.

An energy absorbing structure configured to buckle in response to an impulsive load includes a facesheet and a micro-truss core coupled to the facesheet. The facesheet and the micro-truss core are wound together into a hollow tube structure. The hollow tube structure may have any shape suitable for the intended application of the energy absorbing structure, including prismatic shapes, non-prismatic shapes, axisymmetric shapes, and non-axisymmetric shapes. In one embodiment, the stiffness of the micro-truss core varies axially, radially, and/or circumferentially along the energy absorbing structure.

A vibration isolation apparatus 1 includes: a laminated elastic body 8 in which elastic layers 3 and rigid layers 7 are alternately laminated and a circularly columnar body 14 which is constituted by damping bodies 12 press-fitted in a circularly columnar hollow portion 11 of the laminated elastic body 8, wherein each of the damping bodies 12 contains a thermally conductive filler, a graphite, and a thermosetting resin.

The invention relates to a process for making high-performance polyethylene multi-filament yarn comprising the steps of a) making a solution of ultra-high molar mass polyethylene in a solvent; b) spinning of the solution through a spinplate containing at least 5 spinholes into an air-gap to form fluid filaments, while applying a draw ratio DRfluid; c) cooling the fluid filaments to form solvent-containing gel filaments; d) removing at least partly the solvent from the filaments; and e) drawing the filaments in at least one step before, during and/or after said solvent removing, while applying a draw ratio DRsolid of at least 4, wherein in step b) each spinhole comprises a contraction zone of specific dimension and a downstream zone of diameter Dn and length Ln with Ln/Dn of from 0 to at most 25, to result in a draw ratio DRfluid=DRsp*DRag of at least 150, wherein DRsp is the draw ratio in the spinholes and DRag is the draw ratio in the air-gap, with DRsp being greater than 1 and DRag at least 1. The invention further relates to a high-performance polyethylene multifilament yarn, and to semi-finished or end-use products containing said yarn, especially to ropes and ballistic-resistant composites.

A display device may include a display panel, a first adhesive layer attached on one surface of the display panel, a polymer layer attached on the display panel via the first adhesive layer, a second adhesive layer attached on a surface other than a surface of the first adhesive layer which has been attached on the one surface of the display panel, and a heat sink layer attached on the polymer layer via the second adhesive layer, wherein the at least one of the first adhesive layer, the polymer layer, and the second adhesive layer includes a color changing ink.

An abrasion resistant material for use in the fabrication of protective garments that has at least two layers, a first layer and a second layer, wherein the first layer is the layer that is exposed to and engages with the abrasive surface, such as a road surface. The second layer comprises of substantially high tensile and burst strength so as to act as a protective layer which covers or is at least located closest to the skin of the wearer. The first layer has a plurality of abrasion resistant members dispersed throughout the first layer that act to absorb the bulk of any abrasion force and reduce the exposure and degradation of the second layer

The present invention relates to a flexible ballistic armor apparatus for deflecting high velocity firearm, fragmentation, or shrapnel projectiles with a flexible armor unit. The apparatus minimizes the deterioration of the armor when subjected to shock waves or shear forces of a ballistic impact. The present invention also relates to the use of a flexible armor unit with soft body armor, a vehicle, a vessel, an aircraft or in structural applications.

The cargo liner is configured for use with a cargo carrying vehicle. The cargo liner is a protective structure that covers the supporting surface of the cargo carrying vehicle that supports the cargo. The cargo liner forms a protective barrier that prevents the cargo from damaging the supporting surface. The protective barrier formed by the cargo liner transfers the load of the cargo to the supporting surface of the cargo carrying vehicle that supports the cargo. The cargo liner is formed from a composite material. The cargo liner is temperature resistant. By temperature resistant is meant that has a melting point greater than 500 F (260 C). The composite material that forms the cargo liner has a structure selected from the group consisting of: a) a base structure; b) a flexible structure; and, c) a panel structure.

The present invention relates to a structure for producing ballistic protection which combines high levels of performance in terms of stopping bullets and reducing trauma with great flexibility and breathability. A ballistic laminate comprising joined together unidirectional layers is produced. The ballistic laminate provided by the present invention is preferably produced by superposing at least two layers of ballistic yarns 101 and 103, arranged unidirectionally according to directions inclined relative to one another by approximately 90° (+/−10°). Each layer comprises a plurality of fibres arranged unidirectionally according to a substantially mutually parallel direction (+/−10°).

A body impact protection system includes an inner layer and an impact force dampening and defusing structure. The inner layer includes a material composition and is adjacent to a body part when the body impact protection system is worn. The impact force dampening and defusing structure is juxtaposed to the inner layer and includes a plurality of components. The components function to reduce pressure on the body part from an impact force on a layer by layer basis. Each layer of the system dampens and defuses the impact force such that, by the time it reaches the body part, it has been substantially attenuated and spread over a large area.
