  • Patent number: 9409321
    Abstract: A shaped body and a method for producing fiber composite components, wherein the shaped body is formed using a paper and/or cardboard material, at least in part. This makes possible cost-effective manufacture of hollow profiles of any desired length from fiber composite materials, in particular from prepreg materials and/or reinforcing fiber arrangements which are subsequently impregnated with a curable plastics material. The paper and/or cardboard material can be provided with further properties, such as gas-tightness and non-stick properties, by applying suitable functional layers. Moreover, the material makes it possible to produce highly dimensionally stable shaped bodies or support cores, in such a way that fiber composite components having highly reproducible spatial dimensions can be produced. In addition, after curing, the shaped bodies can be collapsed in a simple manner by applying a vacuum and thus removed from the fiber composite component without residues.

  • Patent number: 8088236
    Abstract: The present invention provides an apparatus and a method for producing a large-area fibre-composite structural component, in particular for the aircraft sector, comprising a predetermined shaping element, a controllable laying device for the defined laying of at least one fibrous sheet over or into the predetermined shaping element, a controllable turning device for a defined turning of the predetermined shaping element and of the laying device in relation to each other by a predetermined turning angle, and a central control device, which is connected to the laying device and the turning device for controlling of the same.
