Problems solved by technology

[0007] The main disadvantage of the above method is that both the device itself and the forming tool used for the manufacture are heavily polluted due to the drip-based lamination bundle / roving bundle
[0008] In particular contamination of the helical grooves of the forming tool leads to adhesion of the laminate bundle to the forming tool and causes large, undesired tolerances
In addition, high cleaning costs are incurred, which leads to long downtimes even after short production cycle times and thus prevents process continuity

Embodiment Construction

[0068] figure 1 A first section of the device according to the invention for producing a spring 34 from fiber composite material according to a first exemplary embodiment is shown.

[0069] The first section of the plant comprises a wet winding device 1 as a processing device 1 for preparing an impregnated fiber bundle 2 (lamination bundle), a coating unit 15 for forming a protective sheath 16, a push lamination Conveyor unit 6 and slitting device for bundle 2.

[0070] The processing device 1 for producing laminated bundles 2 comprises a draw-off unit 3 with a storage roller 4 equipped with a flexible bundle-shaped spring core or core element 5, from which a conveying unit 6 continuously draws Take out the spring core. The bundle-shaped spring core 5 is made of plastic in the present exemplary embodiment and has a circular cross section.

[0071] The drawn flexible spring core 5 is wetted with the matrix material 8 by means of the first impregnation system 7 .

[0072] It...

Abstract

The invention relates to a method for producing a spring from a fiber composite material, in which method a laminated bundle composed of fibers of the fiber composite material and impregnated with a consolidated matrix material is formed into a spring geometry. The invention also relates to a device for carrying out the method. With regard to the method it is proposed that, prior to shaping the laminated bundle (2), a bundle-shaped preform (20) is produced in such a way that a deformable Protective sleeve (16). With regard to the device it is proposed that a coating unit (15) for producing a protective sheath (16) around the laminate bundle (2) is arranged downstream of the processing device (1) in the transport direction of the laminate bundle (2).

Description

technical field [0001] The invention relates to a method for producing a spring from a fiber composite material, in which a laminate bundle composed of fibers of the fiber composite material and impregnated with a consolidated matrix material is formed into a spring geometry. [0002] The invention relates to a plant for carrying out the method, in particular for the production of springs from fiber composite materials, comprising a processing device for producing a laminated bundle composed of fibers and impregnated with a consolidated matrix material . [0003] The invention also relates to a spring made of fiber composite material. Background technique [0004] Methods and apparatus for producing springs from fiber composite materials are well known. Springs produced in this way are used, for example, in the automotive industry. [0005] To produce springs of this type, for example, fibers / rovings impregnated with matrix material are continuously twisted into fiber bun...
