A frangible laminate includes first, second and third webs, and the second web is positioned between the first and third webs. The forming of the frangible laminate includes adhesively bonding a first plurality of sections of the second web to the first web, applying release material in order to inhibit at least some of any bonding between the first plurality of sections of the second web and the third web, and adhesively bonding a second plurality of sections of the second web to the third web. The frangible laminate is separated into a first laminate and a second laminate, so that the first laminate includes the first web and the first plurality of sections of the second web, and the second laminate includes the third web and the second plurality of sections of the second web.

A method for bonding two fiber composite components with each other to form a fiber composite structure includes integrating conductive fibers underneath a bonding surface of at least one of the two fiber composite components, each conductive fiber comprising a carbon fiber coated with an electrically insulating coating, the conductive fibers running along the bonding surface and protruding at least at their ends from the respective fiber composite component; arranging the two fiber composite components against each other at their respective bonding surfaces; passing an electric current through the conductive fibers by electrically contacting the conductive fibers at their protruding ends so that the respective fiber composite component is heated at the bonding surface to a curing temperature; and joining the two fiber composite components with each other at their bonding surfaces via secondary bonding, co-bonding and/or co-curing at the curing temperature, thereby forming the fiber composite structure.

A method to produce a veneered element, the method including applying a first layer on a substrate, applying a second layer on the first layer, applying a veneer layer on the second layer, pressing the first layer, the second layer and the veneer layer together to form a veneered element, wherein, after pressing, the second layer is transparent or translucent such that the first layer is visible through a crack, cavity, hole and/or knot of the veneer layer. Also, such a veneered element.

A sheet-shaped insulating member including a thermoplastic resin fiber and an inorganic fiber is arranged on a surface of a magnet body. The insulating member is compressed while being heated to a temperature higher than or equal to a glass transition temperature of the thermoplastic resin fiber, so that the insulating member is thermocompression-bonded to the magnet body in a state in which the inorganic fiber is elastically compressed. A magnet is thus formed. With the magnet arranged in a slot of a rotor core, the magnet is heated to a temperature higher than or equal to the glass transition temperature of the thermoplastic resin fiber. This causes the inorganic fiber to restore elasticity, so that the magnet is fixed to the rotor core.

Systems and methods for assembling elongate composite structures are disclosed. The systems include a first rigid elongate cure tool defining a first elongate support surface for supporting a first elongate charge of composite material (FEC), a second rigid elongate cure tool defining a second elongate support surface for supporting a second elongate charge of composite material (SEC), and a flexible elongate caul plate. The systems further include a vacuum compaction film, a translation structure, and a vacuum source. Methods according to the present disclosure include positioning a vacuum compaction film, positioning a flexible elongate caul plate, and positioning an FEC. The methods further include positioning an SEC, contacting a region of the FEC with a region of the SEC, sealing the vacuum compaction film, evacuating the enclosed volume to generate an elongate composite assembly, and heating the elongate composite assembly to define the elongate composite structure.

A method of manufacturing a product including at least two carbon parts including the step of: manufacturing a first carbon part, manufacturing at least a second carbon part, providing on a surface of one of the first carbon part or second carbon part a plurality of protrusions including a carbon resin, joining together the first carbon part and the second carbon part in such a way that the plurality of protrusions is interposed between the first carbon part and second carbon part for providing physical and electrical connection is provided.

Methods of producing polymer-metal hybrid components that are bonded by C—O-M bonds at the interface using at least one of the hot pressing, rolling, and injection molding methods to create chemical bond formation conditions at the polymer and metal interface. When the thermal cycle and compressive pressure specified herein is combinationally created at the polymer and metal interfaced, strong C—O-M bonds forms at the interface and strongly bonds the metal and polymer together through the reaction carbonyl groups (C═O) in polymer and the metal surface. For polymers lacking enough carbonyl groups, new functional groups can be in-situ generation through introducing distributed air pockets at the polymer-metal interface for forming 3-dimensional distributed C—O-M bonds at the interface.

The cutting of fibrous material which does not melt easily is effected to avoid the unravelling of cut edges, using ultrasonic or laser beam techniques. The method includes (a) applying a thermoplastic powder material to the cutting region, and (b) applying thermal shock to the localised area, sufficient to destroy the fibres of the material, and melt the powder on either side of the cut, and (c) pressing the cut edges while the fused thermoplastic powder is still soft. Woven or non-woven fabrics have tendency to unravel, after cutting, and normally require a sewn hem. The method of the invention disposes of the sewn hem, and provides a thermo-cutting technique applicable to non-fusible or non-thermoplastic fibres.

Laminated light-blocking decorative articles are prepared by applying an aqueous foamed opacifying composition to a decorative fabric, drying, laminating a non-woven fabric to the resulting dry foamed opacifying layer, and densifying that layer to have a thickness that is at least 20% less than before densifying. This operation can be carried out so that non-woven fabric, decorative fabric, and aqueous foamed opacifying composition are supplied in a single-pass, in-line operation to make any quantity of laminated light-blocking decorative article. The applied aqueous foamed opacifying composition has 35%-70% solids and a foam density of 0.1-0.5 g/cm.sup.3. It is composed of (a) porous particles, (b) a binder material, (c) two or more additives comprising at least one foaming surfactant and at least one foam stabilizer, (d) an aqueous medium, and (e) at least 0.0001 weight % of an opacifying colorant that absorbs electromagnetic radiation having a wavelength of 380-800 nm.

An assembly for forming a structural, insulating or decorative article as any of a roll, sheet, board or panel and including a width extending die and extruding nozzle for issuing a flowable polymeric material having either of a solid or ribbed cross sectional profile and including any of a polyurethane, a polypropylene or any other polymeric material. At least a pair of opposing and rotating pinch rollers are arranged for receiving therebetween the flowable material. A material roll simultaneously feeds a material layer between the rollers and against the flowable polymer material at a given pressure to cause the polymeric material to fuse and embed within the material layer. The material separate material layer can further include any structural panel, multi-panel or pallet style construction, such including both solid and interiorly hollowed/corrugated constructions.
