A method for producing a structural component part (1) from a fiber-reinforced plastic according to a three-dimensional winding process. Threadlike or strand-shaped fiber material (12) supplied on at least one bobbin (18) is wound around at least one filament carrier (11) in at least one winding pattern by at least one computer-controlled winding device (10). The fiber material (12) is laid down on the filament carrier (11) with a filament tensile force (FZN) that is preadjusted by a control device (14). The filament tensile force (FZist) is controlled depending on location and/or depending on path in order to take into account specific lay-down locations (29) on the filament carrier (11) in which a lay-down path (28) predefined by the winding pattern is departed from owing to the local geometry at preadjusted filament tensile force (FZN).
A method for producing a structural component part from a fiber-reinforced plastic according to a three-dimensional winding process, wherein threadlike or strand-shaped fiber material which is supplied on at least one bobbin is wound around at least one filament carrier in at least one winding pattern by means of at least one computer-controlled winding device, wherein the fiber material is laid down on the filament carrier with a filament tensile force (FZN) that is preadjusted by a control device, wherein the filament tensile force (FZist) is controlled depending on location and/or depending on path to take into account specific lay-down locations on the filament carrier in which a lay-down path predefined by the winding pattern is departed from owing to the local geometry at preadjusted filament tensile force (FZN).
A computer-controlled winding device for producing a structural component part from a fiber-reinforced plastic according to a three-dimensional winding process, wherein the computer-controlled winding device is adapted to wind a threadlike or strand-shaped fiber material supplied on at least one bobbin around a filament carrier according to at least one predefinable winding pattern with a filament tensile force (FZist), wherein the winding device is adapted to lay down the fiber material on the filament carrier with a filament tensile force (FZN) preadjusted by a control device, wherein the winding device is controlled to adjust the filament tensile force (FZist) depending on location and/or depending on path to take into account specific lay-down locations on the filament carrier in which a lay-down path predefined by the winding pattern is departed from because of the local geometry at preadjusted filament tensile force (FZN).
