Abstract: A method for producing solidified fiber bundles includes applying a melt or solution to a carrier web forming a viscous coating, applying parallel filaments under tension to the carrier web, and pressing the filaments into the viscous coating, forming an impregnate. The coating is partially solidified until a plastically deformable state of the impregnate is obtained by vaporizing the solvent, thermal curing and/or cooling. The impregnate is rolled onto a winding core to form a roll while maintaining a winding tension of the filaments in the impregnate. The outer roll is fixed on the winding core by a sleeve and/or by adhesive tape. The impregnate is solidified by vaporizing the solvent, thermal curing and/or cooling. The solidified impregnate is divided up to form solidified fiber bundles. A pressure produced by the winding tension of the filaments in the impregnate is exerted on the roll.

Abstract: A load-pulling system includes a least one belt to which a tensile load is applied. The belt is formed of a matrix and a load-bearing fiber structure embedded in the matrix and having a plurality of fibers. The belt is guided around a least one deflection device in such a way that it forms a curved section in the region of the deflection device. A dimensioning of the belt and the applied tensile load are matched to each other in such a way that, in the curved section of the belt, a zero stress line of the belt is displaced radially inward in the direction of curvature with respect to a center line of the load-bearing fiber structure by an amount of at least 25% of the thickness of the load-bearing fiber structure.

Abstract: A cable contains filaments containing carbon, surrounded by a sizing. The filaments surrounded by the sizing are covered by a matrix which is composed of a material containing at least one elastomer and/or at least one thermoplastic elastomer. The cable can be used, in particular for pulling a load, for example in a goods lift.

Abstract: A material composition is formed with a carrier component and an additive component. The additive component has one or more ceramic additives. The carrier component and the additive component are present in a ratio by volume in the range from approximately 1:9 to approximately 7:3, preferably in the range from approximately 1:4 to approximately 2:1. More particularly, they are present in a ratio of approximately 1:1. The material composition may be formed as a foil or as a liquid, viscous, paste or gel material. The material composition may be used, inter alia, as oxidation protection and as a sealing element.

Abstract: The invention relates to a method for producing a fibre layer with a longitudinal direction, wherein the method is based on the fact that fibre bundles having the same or a different fibre fineness which are guided in parallel are guided together in an overspread, overlapping manner and as a result are mechanically strengthened, wherein at least one sliver is obtained as a unidirectional layer with a defined width without additional fixing agent and/or additional mechanical or physical fixing methods.
