Disclosed is a method for producing components from fiber-reinforced thermoplastic on the basis of fiber tapes impregnated with matrix material. The method includes manufacturing a multitude of semi-finished products, each of which has a plurality of non-consolidated layers of fiber tapes. The semi-finished products are placed in a consolidation device in such a way that the semi-finished products are in direct contact with one another. The semi-finished products are then consolidated using the consolidation device and the semi-finished products are at least partially joined to one another during the consolidation process. The joined semi-finished products are then cut apart using a cutting device.

A reinforcement sheet has a composite layer including fibres and a polymer A and a coating layer including polymer B, each polymer having at least 65 mol % of a repeat unit of formula:

##STR00001##

wherein for each polymer A and B, t1, and w1 independently represent 0 or 1 and v1 represents 0, 1 or 2. A method of forming the reinforcement sheet is also disclosed, in addition to a method for forming an article comprising a laminate of the reinforcement sheets and the article comprising such a laminate. The repeat unit may be ether-ether-ketone.

A flat metallic structure having a multiplicity of openings and having a width between 6 and 1000 mm. The metallic structure is treated with a metallic impregnating material whose melting point is lower than that of the flat metallic structure, and wherein the conductivity of the metal before the impregnation is at least 15 S/m. A use of such a structure as lightning protection for fiber composite components, as well as fiber composite components having such a structure, and a method for the production of such fiber composite components.

Disclosed is a method for producing components from fiber-reinforced thermoplastic. The method involves manufacturing a multitude of semifinished products, each of which includes a plurality of impregnated fabric layers that are joined to one another only locally, as well as a frame structure having at least one cutout. The semifinished products are consolidated using a consolidation device, an inlay element being placed in each cutout before the semifinished products are consolidated.

A process for fabricating a partially polymerized prepreg material. Fibers are impregnated with thermosetting resin. The resin is partially polymerized to a degree of polymerization between 10% and 60%. The thermosetting composite parts are produced by drape forming of the prepreg material. The material laid-up in the form of tapes and heated at a temperature above the glass transition temperature of the prepreg state. The laid-up material is pressed and cooled to return the laid-up material to a temperature below the glass transition temperature of the prepreg state in question.

The present invention discloses a device for producing a reinforcing structure, which comprises a strip that is fibre-reinforced and comprises thermoplastic material, on the surface of a moulding. The device is characterized in that it is designed such that the laser diode array directly irradiates the heating-up area of the strip and/or the heating-up area of the surface of the moulding or of the already formed reinforcing structure, wherein the laser diodes of the laser diode array are formed as surface emitters.

A composite structure is fabricated by laying up at least one ply of fiber reinforcement and at least one layer of resin on a tool. The resin film layer is formed by laying strips of resin film. The fiber reinforcement is infused with resin from the resin layer.

A composite manufacturing apparatus includes a width determining mechanism and a gas supplier. The width determining mechanism has a body and a gas passage. The body has a path configured to allow a tape material including fibers impregnated with a resin to pass therethrough. The path has a bottom surface and a pair of wall surfaces. The pair of the wall surfaces form a gap that gradually decreases. The gas passage is provided inside the body and formed by the bottom surface having a plurality of through holes, and is in communication with the plurality of through holes. The gas supplier is configured to supply gas to the gas pass age.

A scrap collection assembly for a tape lamination head that applies a plurality of composite tape segments includes a crack-off assembly with a scrap crack-off redirect roller configured to engage one or more composite tape segments and one or more scrap portions; a secondary crack-off roller configured to engage one or more composite tape segments and one or more scrap portions; a pivot that connects the crack-off assembly to the tape lamination head, wherein the secondary crack-off roller selectively moves about the pivot to change a direction of composite tape movement; and a conveyor that receives the scrap portion(s) from the secondary crack-off roller.
