A thermoplastic product includes a fabric-based reinforcing sheet and a polymerized thermoplastic material. The fabric-based reinforcing sheet is wound about a mandrel to form a plurality of layers having a cross-sectional shape that corresponds to the mandrel. The fabric-based reinforcing sheet includes a plurality of fiber bundles, which may have a bidirectional orientation or configuration. A polymerized thermoplastic material is disposed within each layer of the fabric-based reinforcing sheet. The polymerized thermoplastic material bonds each layer of the fabric-based reinforcing sheet to an adjacent layer.

A carbon fiber toothed structure has a body. The body is circular and has a toothed segment and at least one carbon fiber cloth. The toothed segment is formed on an outer periphery of the body. The at least one carbon fiber cloth is deposited on a front side and a rear side of the body from a center to the outer periphery of the body to cover the toothed segment. The body is made by stacking multiple circular carbon fiber cloths of different diameters with each other. Some of the carbon fiber cloths deposited in the body have smaller diameters than those of the others of the carbon fiber cloths to enable the center of the body being thicker than the outer periphery of the body. The toothed segment has two guiding inclined planes respectively deposited on the front side and the rear side of the body.

A method for manufacturing panels with at least a substrate and a top layer. The method having the steps of providing a granulate having thermoplastic material and having an average particle size of less than 1 millimeter, forming a substrate layer by strewing the granulate, consolidating the layer between the belts of a continuous press device, and providing the top layer on the substrate.

An optical mirror assembly includes a crystalline face sheet and a carbon fiber sandwich. The crystalline face sheet has a first surface configured to reflect light and a second surface coupled to the carbon fiber sandwich by a layer of epoxy. The carbon fiber sandwich is configured to structurally support the crystalline face sheet. The carbon fiber sandwich includes a first carbon fiber layer, a second carbon fiber layer and a substrate positioned between the first carbon fiber layer and the second carbon fiber layer.

The invention relates to a method for continuously manufacturing elastic pants (28), wherein a flat web material (1, 16, 19) is continuously conveyed in a longitudinal direction (8) of the web material (1, 16, 19), is shaped into a closed tube (4), and is closed in the longitudinal direction (8). The closed tube (4) forms a first outer layer (9). Elastic threads (10) in the form of a tubular reinforcement are then wound around the first outer layer (9) in the conveying direction (8) in such a way that the elastic threads (10) are taut when the outer layer (9) has a convex shape. A second outer layer (15) is then continuously applied to the elastic threads (10) in the conveying direction (8) and is joined to the elastic threads (10) and/or the first outer layer (9). The first outer layer (9), the elastic threads (10) and the second outer layer (15) form an elastic pants web material (21). Further down in the conveying direction (8), the pants web material (21) is closed along a joining section (29) in regular intervals such that the joining section (29) forms two approximately equally large opening sections that lie opposite each other in the transverse direction. Further down in the conveying direction (8), the pants web material (21) is cut at a distance from the joining section (29) such that a pair of elastic pants (28) is formed.

A method to prepare a composite laminate object containing an extrusion grade 7xxx Al substrate and a fiber-reinforced polypropylene layer adhesively laminated to the substrate; is provided. The process includes shaping and cutting an extruded 7xxx aluminum to a profile, assembling a layered arrangement of the 7xxx Al profile as substrate, an adhesive film and a fiber reinforced polypropylene preform, heating the layered arrangement to a temperature of 160-175 C. to melt the polypropylene and activate the adhesive film, applying pressure to at least a surface of the fiber reinforced polypropylene preform to mold the preform to the shape of the extruded 7xxxAl substrate and obtain a semi-finished laminate object, cooling the semi-finished laminate object to 90 C., optionally, cooling the semi-finished laminate object to room temperature for inventory storage; heat treating the semi-finished laminate object at 90 C. for 2 to 8 hours; and then heat treating the semi-finished laminate object at 130 C. to 150 C. for 8 to 16 hours; and cooling the heat treated object to obtain the composite laminate object.

Disclosed are a vehicle back beam capable of maximizing impact performance and reducing product weight; and a vehicle including same. According to one embodiment of the present invention, provided is a vehicle back beam which includes: a back beam body; and a back beam reinforcing part which is formed in at least one section of the back beam body and composed of a highly deformable composite material.

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 filaments on one surface of the backing, and pressure-sensitive adhesive layer that coats the filaments and binds them to the backing.

In one aspect, the present invention provides a fiber reinforced metal composite comprising 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. In another aspect, the present invention discloses an application of fiber reinforced metal composite in the field of luggage case manufacturing, provides two preparation methods for providing fiber reinforced metal case shell with simple and available operations.
