Resin Line with Flow Aid

Abstract

The invention relates to a resin line (2) with openings on the circumference and a sleeve made of a flow aid material (4). The aim of the invention is to design the resin line such that the resin line does not leave impressions on the surface of the component under the effect of a vacuum and the resin dispensing process is improved. This is achieved in that the flow aid material (4) is placed about the resin line (2) such that the flow aid material (4) tabs (8) projecting beyond the resin line (2) form a double-layer web (6), in the region of which the tabs (8) are connected together.

Claims

1-8. (canceled)

9. A resin line assembly, comprising: a resin line comprising openings at a circumference of the resin line; a flow aid material enveloping the resin line and placed about the resin line such that flaps of the flow aid material project away from the circumference of the resin line, wherein the flaps are arranged to form a double layer stay and are connected to each other in an area of the double layer stay.

10. The resin line assembly according to claim 9, further comprising an angled section that adjoins the double layer stay at an end of the double layer stay facing away from the resin line.

11. The resin line assembly according to claim 10, wherein at least one of the flaps has a section adjoining the double layer stay is folded into a loop and the loop forms the angled section.

12. The resin line assembly according to claim 11, further comprising a support material that is placed into the loop and connected to the loop to reinforce the angled section.

13. The resin line assembly according to claim 10, wherein the flaps in a section adjoining the double layer stay are folded into loops and the loops form the angled section.

14. The resin line assembly according to claim 13, further comprising a support material that is placed into the loops and connected to the loops to reinforce the angled section.

15. The resin line assembly according to claim 13, wherein the loops are folded such that free ends of the flaps have a spacing relative to each other and form a gap.

16. The resin line assembly according to claim 10, further comprising a support material that is connected to the angled section to reinforce the angled section.

17. The resin line assembly according to claim 9, wherein the flaps are connected to each other in the area of the double layer stay by at least two seams spaced apart from each other.

18. The resin line assembly according to claim 9, further comprising a tear-off fabric placed onto the flow aid material.

Description

[0017] Further modifications and configurations of the invention can be taken from the following subject matter description.

[0018] The invention will now be described with the aid of one embodiment in more detail. In the attached illustration, a resin line 2 is shown through which a matrix material is guided. Through openings, not illustrated in detail in the drawing, the matrix material can penetrate from the interior of the resin line 2 to the exterior. Here, it is in contact with the flow aid material 4 which is placed as an envelope about the resin line 2.

[0019] The flow aid material 4 is dimensioned such that, extending beyond the circumference of the resin line 2, flaps 8 are projecting past the circumference of the resin line 2 which in a section form a double layer stay 6. The two projecting flaps 8 of the flow aid material 4 are connected to each other in the area of the stay 6 by two indicated seams 10.

[0020] At the end of the stay 6 facing away from the resin line 2, a section 12 that is angled relative thereto is provided. In the embodiment, the angled section 12 is comprised of two loops 14 into which the two ends of the flaps 8 are folded. The two loops 14 in the embodiment are also secured by seams 10. The ends of the flaps 8 are placed in the loops 14 such that they have a spacing relative to each other and a gap 16 between the two ends remains.

[0021] In the embodiment, a layer of a support material 18 has been placed into the loops 14. The support material should be penetrable for the matrix material so that the latter is not impaired when flowing out from the resin line 2 into the tool.

[0022] The afore described embodiment serves only for explaining the invention. The invention is not limited in any way to the embodiment. A person of skill in the art will have no difficulties in modifying the embodiment in a way appearing suitable to him in order to adapt it to a concrete application situation.
