  • Patent number: 9707747
    Abstract: A method for producing a flat prepreg material blank impregnated with at least one matrix resin in an at least partially automated production system. The method includes cutting the fibrous material in a blanking station to the geometry of the particular prepreg material blank to be produced. The resultant fibrous blank is subsequently impregnated in an impregnation station. Then, the resultant single prepreg layer is joined in an assembly station with at least one further single prepreg layer, which was previously impregnated in the impregnation station, to form a multiple-layer prepreg material blank.
    Type: Grant

  • Patent number: 9259876
    Abstract: A method for producing a substantially shell-shaped, fiber-reinforced plastic part includes preheating a material blank that is formed of a fibrous material impregnated with a matrix material using a heating device to ensure the formability and placing the preheated material blank into a shaping tool having an upper die and a lower die. The shaping tool is then closed to form the material blank. Using a cooling device, at least one shaping surface of the shaping tool, with the material blank inserted, is at least partially cooled.

  • Publication number: 20130256951
    Abstract: A shaping tool is constructed for producing a substantially shell-shaped, fiber-reinforced plastic part. The shaping toll includes and upper die and a lower die. A material blank made substantially of fibrous material is placed into the lower die the shaping tool brought into shaping engagement with the material blank. At least one of the dies is segmented into shaping segments for being brought into shaping engagement with the material blank in segments or in groups of segments.
