A fiber reinforced metal composite having a metal layer and a fiber layer which are arranged in a stack, and adjacent layers are fixed by bonding; the composite has a two-layered or three-layered structure, wherein one layer is closely adhered to another layer and the thickness of the layer is from 0.6 mm0.9 mm. Such structure changes the structure of the existing fiber metal composite characterized by generally having more than three layers, and greatly reduces the thickness of the composite while maintaining good mechanical properties. Also disclosed is an application of fiber reinforced metal composite in the field of luggage case manufacturing, providing two preparation methods for providing fiber reinforced metal case shell with simple and available operations.

A panel including at least a substrate of thermoplastic material and a top layer with a printed decor and a translucent or transparent wear layer. The substrate has a thickness larger than one half of the thickness of the entire panel, and the substrate at least includes two layers, where the two layers each include thermoplastic material. A first one of the two layers further includes at least 60 percent by weight of filler materials and a second one of the two layers includes less fillers or is not filled, and is situated above the first one of the two layers.

A carpet tile having a greige good, an adhesive layer, and a secondary backing material. The greige good has a primary backing component and a plurality of fibers attached to the primary backing component. The adhesive layer has an adhesive composition and a reinforcement material that is at least partially embedded within the adhesive composition. The adhesive layer is applied to a back surface of the primary backing component. The secondary backing material is adhered to the primary backing component by contact with a portion of the adhesive composition that flows through the reinforcement material. The reinforcement material and the secondary backing material are co-laminated onto the adhesive composition.

A member for use in undersea applications comprising a plurality of conduits assembled into a bundle; the bundle being wrapped with a pressure-sensitive tape comprising a backing, a layer of corrosion-resistant yarns on one surface of the backing, and pressure-sensitive adhesive layer that coats the corrosion-resistant yarns and binds them to the backing.

An object is to provide a composite material manufacturing method for improving interlayer strength. The present disclosure provides a composite material manufacturing method of laminating a plurality of prepregs (10) formed of a fiber reinforced base material impregnated with an uncured matrix resin and performing hot molding, the method including: using the prepregs (10) each provided with a gap layer (12) that does not contain a resin and is continuous in an in-plane direction and resin layers (11a, 11b) disposed on both surfaces of the gap layer; disposing a plurality of short fibers (13) on facing surfaces of the prepregs (10) that are adjacent to each other; and evacuating the laminated prepregs (10) to degas the gap layer (12) and then performing hot molding.

Systems and methods for filament fastener that cures with composite part. One embodiment is a method of fabricating a composite part. The method includes placing layers of reinforcement fibers over a tool to form a laminate of composite material to be cured with a first resin, forming a filament fastener comprising bundled fibers with one or more texture elements around the bundled fibers, and coating the filament fastener with a second resin that is chemically compatible with the first resin. The method also includes inserting the filament fastener into the laminate through a plurality of the layers, and curing the filament fastener within the laminate to bind the plurality of the layers of the laminate with the one or more texture elements of the filament fastener via bonding of the first resin and the second resin to form the composite part with delamination resistance.

As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color.
