Method and device for producing a near-net shape preform

摘要

Method for producing a near-net-shape preform for a fiber composite component, in which filament-like or strand-like reinforcing material is taken from a fixed supply and arranged in at least one layer of mutually parallel sections, the reinforcing material being laid with a linearly movable laying mechanism and the reinforcing material on a rotatable one Table is fixed with fixing elements arranged approximately to the end contour, characterized in that each section to be installed is first deducted from the supply by an installation means belonging to a laying station, in the length relevant between a suitable installation location and the resulting preform between this and a further installation means is recorded and separated between the further laying means and the supply, experienced and stored, whereby it is temporarily fixed by one fixed and two translationally movable clamps above the table, - the fixation elements are arranged on an interchangeable frame arranged on the translationally movable table, approximating the final contour of the preform to be manufactured, the translationally movable clamps, which are movable in a direction different from the translational movement, transfer the reinforcing material to the fixing elements and the resulting preform and the laying station are offset from one another by at least a distance corresponding to the width of the reinforcing material section.
