METHOD OF MANUFACTURING INTERMEDIATE PRODUCT OF AIRCRAFT PART AND AIRCRAFT PART

A first laminated body is worked to form a second laminated body, the first laminated body being formed by laminating prepregs including reinforcing fibers and resin, the second laminated body including a flat portion and a wavy portion, the flat portion being located at at least one of side edge portions of the second laminated body, the wavy portion being located at a portion adjacent to the side edge portion and extending along a longitudinal direction. An intermediate product is formed from the second laminated body by a forming die such that the flat portion becomes a bent portion that is an inside portion whose circumferential length is shorter in a curved portion, and the wavy portion becomes a bent portion that is an outside portion whose circumferential length is longer in the curved portion.

EFFICIENT PRODUCTION OF COMPOSITE SEMIFINISHED PRODUCTS AND COMPONENTS IN A WET PRESSING METHOD USING HYDROXY FUNCTIONALIZED (METH)ACRYLATES WHICH ARE DUROPLASTICALLY CROSSLINKED USING ISOCYANATES OR URETDIONES

The invention relates to a process for producing semi-finished composites and composite components. For production of the semi-finished products or components, (meth)acrylate monomers, (meth)acrylate polymers, polyfunctionalized (meth)acrylates, hydroxy-functionalized (meth)acrylate monomers and/or hydroxy-functionalized (meth)acrylate polymers are mixed with di- or polyisocyanates or with uretdione materials. This liquid mixture is applied by known processes to fibre material, for example carbon fibres, glass fibres or polymer fibres, and polymerized with the aid of a first temperature increase or of a redox accelerator or by means of photoinitiation. Polymerization, for example at room temperature or at up to 120° C., gives rise to thermoplastics which can still be subjected to a forming operation. The hydroxy-functionalized (meth)acrylate constituents can subsequently be crosslinked in a press with isocyanates or uretdiones already present in the system at a second temperature at least 20° C. above the polymerization temperature. In this case, the shaping to give the final component is effected simultaneously in this press. In this way, dimensionally stable thermosets or crosslinked composite components can be produced.
