Abstract

Filling bodies for the use in unstructured packings. The filling body has a fibre-reinforced carbon flat material. Two strip regions of the carbon flat material, which are separated by a cut, transition into two connecting regions of the carbon flat material.

First claim

The invention claimed is:

1. A filling body for use in unstructured packings, comprising: a fibre-reinforced carbon flat material, and two strip regions of the carbon flat material, which are separated by a cut, and transition into one another in two connecting regions of the carbon flat material; the two strip regions forming an alternating pair of strip regions;
wherein one of the two strip regions of the alternating pair of strip regions is separated by the cut and forms a single hump; and
wherein another one of the two strip regions of the alternating pair of strip regions forms a U shape, each end of the U shape comprising a hump; and
wherein the filling body comprises a total of n cuts, resulting in an alternating arrangement of a plurality of adjacent alternating pairs of strip regions, and n is a number ranging from 4 to 35.

2. The filling body according to claim 1 , wherein at least some of the fibres running in at least one strip region extend into both connecting regions.

3. The filling body according to claim 1 , comprising
n cuts and
n+1 strip regions,

wherein n is a number selected from 5, 6, 7, 8, 9, 10 or 11.

4. The filling body according to claim 1 , wherein the cut defines a first cut edge and a second cut edge, which transition into one another at a first and a second cut end of the cut, and a portion of one cut edge is spaced apart from the other cut edge of the same cut.

5. The filling body according to claim 1 , wherein two cut edges of adjacent cuts delimit a given strip region, and the cut edges delimiting the given strip region run parallel to one another.

6. The filling body according to claim 5 , wherein the two other cut edges of the adjacent cuts also run parallel to one another.

7. The filling body according to claim 1 , wherein both cut edges of the same cut lie in one plane.

8. The filling body according to claim 1 , wherein the fibre-reinforced carbon flat material comprises fibres selected from glass fibres, basalt fibres and carbon fibres.

9. The filling body according to claim 1 , wherein the fibre-reinforced carbon flat material comprises at least one unidirectional region in which the fibres do not cross.

10. The filling body according to claim 9 , wherein the fibre-reinforced carbon flat material comprises at least two unidirectional strip regions adjacent to both cut edges of the same cut.

11. The filling body according to claim 9 , wherein a unidirectional strip region extends from one cut edge of a given strip region to the other cut edge of the same strip region and from the first cut ends of the two cuts to the second cut ends of the two cuts.

12. The filling body according to claim 9 , wherein the unidirectional region extends over the entire carbon flat material.

13. The filling body according to claim 1 , wherein the fibre-reinforced carbon flat material comprises at least one multidirectional region in which the fibres cross.

14. A column having an unstructured packing comprising filling bodies according to claim 1 .

15. A method for producing a filling body according to claim 1 , wherein a fibre-reinforced starting flat material is fed into a press-and-cutting zone, and the starting flat material is shaped, cut up and cut through in the press-and-cutting zone so as to form a body which comprises a fibre-reinforced flat material and in which two strip regions of the flat material separated by a cut transition into one another in two connecting regions of the flat material.

16. The filling body according to claim 1 , wherein each of the two strip regions separated by the cut is configured in a curved shape, the other one of the two strip regions comprises two more turning points compared to the one of the two strip regions.

17. The filling body according to claim 1 , wherein the cut defines a first cut edge and a second cut edge, a distance between one point of the first cut edge and a corresponding point of the second cut edge is at least 1/6 of a length of each cut edge, wherein the one point and the corresponding point are immediately adjacent to one another before cutting the carbon flat material.

18. The filling body according to claim 1 , wherein all cuts have equal lengths.
