In an example, a composite structure having a variable gage is described. The composite structure includes a first end having a first gage, a second end having a second gage, which is less than the first gage, a plurality of continuous plies, and a plurality of drop-off plies. Each continuous ply extends from the first end to the second end. Each drop-off ply includes a tip having a tapered shape. Each drop-off ply extends from the first end to a respective position of the tip of the drop-off ply between the first end and the second end. The plurality of drop-off plies are separated from each other by at least one of the plurality of continuous plies.

A sensor device has an insulative non-woven fabric and a conductive fabric forming an electrode. The conductive fabric is joined to one surface of the non-woven fabric by at least one of fusion and seaming.

The present invention describes various methods for manufacturing gel composite sheets using segmented fiber or foam reinforcements and gel precursors. Additionally, rigid panels manufactured from the resulting gel composites are also described. The gel composites are relatively flexible enough to be wound and when unwound, can be stretched flat and made into rigid panels using adhesives.

A coated composite component includes, in this order, a composite component, a fluorine-containing film and/or a fluorine-containing woven fabric, knitted fabric or crocheted fabric, and a tear-off fabric. A method for producing a coated composite component including, in this order, a composite component, a fluorine-containing film and/or a fluorine-containing woven fabric, knitted fabric or crocheted fabric, and a tear-off fabric.

There is provided a composite structure, comprising a base member(s) made of metallic material, and a reinforcement member(s) made of fiber reinforced plastic including reinforcement fibers which are aligned in a uni-direction, wherein at least one slit is formed on the reinforcement member(s) so as to extend in an orientation direction of the reinforcement fibers.

Described are composite grid structures that have a plurality of ply layers, each one of the plurality of ply layers comprising a plurality of first elongate tapes oriented in a first direction and a plurality of second elongate tapes oriented in a second direction, the second direction being offset from the first direction by an angle of at least 25 degrees. In the grid structures: each of the first elongate tapes has a first length extending between opposing ends of each of the plurality of first elongate tapes and a first midpoint intermediate the opposing ends, and each of the second elongate tapes has a second length extending between opposing ends of each of the plurality of second elongate tapes and a second midpoint intermediate the opposing ends. Associated composite laminate structures, grid structures, and methods of manufacturing and/or using the same are also disclosed.

An article of manufacture (130) for protecting a capacitive power transfer system (100) from electrical breakdowns is disclosed. The article of manufacture comprises a non-conductive layer (210) made of a first type of non-conductive material, and a protection layer (220) made of a second type of non-conductive material, wherein a breakdown voltage of the second type of non-conductive material is higher than a breakdown voltage of the first type of non-conductive material, wherein the protection layer covers only a portion of the non-conductive layer, where in the non-conductive layer and the protection layer form an insulating layer (130) of the capacitive power transfer system.

A dry adhesive backed flooring for being installed in a flat orientation on a subfloor, the flooring including a sheet flooring material and a double-sided sheet adhesive married to the flooring material. The installed flooring is substantially free of bubbles and wrinkles and the flooring remains substantially flat as initially applied and does not significantly rise from the subfloor, bubble or otherwise detach from the subfloor under normal use conditions for the flooring.

An article comprises a multi-directional textile of first reinforcing fiber tows extending in a first direction and second reinforcing fiber tows extending in a second direction. Filaments in the first fiber tows extend past a boundary of the textile and are spread. The tows are embedded in resin.
