SOLIDIFIED FIBRE BUNDLES

摘要

The invention relates to a method for producing solidified fibre bundles, comprising the steps of a) applying a melt or solution to a sheet-like carrier web, thereby forming a viscous coating, b) applying parallel filaments under tension to this carrier web coated in this way, c) pressing the filaments into the viscous coating, thereby forming an impregnate, d) optionally, partially solidifying the coating until a plastically deformable state of the impregnate is obtained by at least one of the steps comprising vaporizing the solvent, thermal curing and cooling, wherein these steps are only performed to the extent that a plastically deformable state is maintained, e) rolling the impregnate onto a winding core to form a roll while maintaining a winding tension of the filaments in the impregnate, f) optionally fixing the outer roll on the winding core by means of at least one sleeve and/or by at least one adhesive tape, g) solidifying the impregnate by at least one of the steps comprising vaporizing the solvent, thermal curing and cooling, and h) dividing up the solidified impregnate, in particular in parallel and perpendicularly to the direction of the filaments to form solidified fibre bundles, wherein a pressure produced by the winding tension of the filaments in the impregnate is exerted on the roll during the performance of step g), and relates to the use of the solidified fibre bundles as a reinforcing means.
