  • Patent number: 9518356
    Abstract: The present invention relates to a method of forming a curved prepreg strip or sheet, especially for use in fabricating a composite component. The method includes providing a strip or sheet of prepreg material having reinforcing fibers and drawing or conveying the prepreg material in a travel direction, wherein the material is drawn or conveyed in the travel direction at a speed which differs across a width of the strip or sheet transverse to the travel direction. Similarly, the invention relates to an apparatus for forming a curved prepreg strip or sheet, having: a mechanism for drawing or conveying a strip or sheet of prepreg material in a travel direction, wherein the mechanism is configured to draw or convey the strip or sheet of prepreg material in the travel direction at a speed which differs across a width of the strip or sheet transverse to the travel direction.

  • Patent number: 9399325
    Abstract: A device for automatically laying and draping a plurality of web-form portions of a dry sheet-like formation, in particular of a multiaxial laid fiber fabric and/or a woven reinforcing fabric to create a profiled preform on a core by repeated laying and draping of the portions in order to produce a reinforcing profile with a composite material. Accordingly at least one portion, is kept in at least one cassette between two roller conveyors ready for laying on the core. As a result of the preferably simultaneous laying of preferably more than one prefabricated portion of the sheet-like formation on the core by means of at least one cassette of the cassette arrangement a profiled preform can be fully automatically laid and draped quickly and with great dimensional accuracy and at the same time with good reproducibility for the production of CRP profiles.

  • Patent number: 7972457
    Abstract: A device for draping and pre-shaping curved profiled structural components of fiber materials includes at least one shaping tool having a curved shaping face which has a profiled cross-section and which defines the outer contour of the profiled structural component. The device also includes a plurality of unwinding devices each for discharging a web-like fiber material, a device for performing a relative movement between the shaping tool and the plurality of unwinding devices for tangentially winding the web-like fiber materials onto the curved shaping face under tension, and a fixing device for finally fixing the shape of all of the web-like fiber materials wound on the curved shaping face. A method of draping and pre-shaping curved profiled structural components of fiber materials is also disclosed.
