Abstract

A method for reinforcing a substrate or textile of a core structure of a component with the following method steps: a continuous semi-finished product is fed, via a feed means, into a cartridge of a conveying means which comprises a plurality of cartridges; the continuous semi-finished product is cut to length using a cutting means in order to produce a cut, reinforcing semi-finished product which is received in the cartridge; the cartridge is conveyed to a machining means; the cut, reinforcing semi-finished product is sharpened using the machining means; the cartridge is conveyed to a textile or substrate to be reinforced of a core structure; and the sharpened semi-finished product is shot into the textile or substrate of a core structure by a stud-shooting means.

First claim

The invention claimed is:

1. A method for reinforcing a substrate or a textile of a core structure of a component, comprising:
(i) feeding a continuous semi-finished product, via a feeder, into a first cartridge of a conveyor, the conveyor comprising a plurality of cartridges;
(ii) cutting to length the continuous semi-finished product using a cutter in order to produce a cut, reinforcing semi-finished product which is received in the first cartridge;
(iii) conveying the first cartridge to a machine;
(iv) sharpening the cut, reinforcing semi-finished product using the machine;
(v) conveying the first cartridge to the substrate or textile to be reinforced; and
(vi) shooting the sharpened semi-finished product into the substrate or textile of the core structure using a stud-shooter.

2. A method for reinforcing a substrate or a textile of a core structure of a component, comprising:
(i′) feeding a continuous semi-finished product, via a feeder, into a first cartridge of a plurality of cartridges of a conveyor;
(ii′) sharpening a free end of the continuous semi-finished product using a machine;
(iii′) cutting to length the sharpened continuous semi-finished product using a cutter in order to produce a cut semi-finished product which is received in the first cartridge;
(iv′) conveying the first cartridge to the substrate or textile of the core structure to be reinforced; and
(v′) shooting the sharpened semi-finished product into the substrate or textile of the core structure using a stud-shooter.

3. The method according to claim 1 , wherein the conveyor moves the plurality of cartridges forwards in an endless loop either continuously or intermittently, whereby in each case the semi-finished products introduced into the respective cartridges are transported from the feeder to the stud-shooter.

4. The method according to claim 1 , wherein the semi-finished products are shot into the textile or substrate of the core structure in previously determinable directions relative to the main axes of the textile or core structure.

5. A device for reinforcing a substrate or a textile of a core structure of a component, comprising:
a conveyor comprising a plurality of cartridges;
a feeder configured to feed a continuous semi-finished product to a respective cartridge of the plurality of cartridges;
a cutter configured to cut a length of the continuous semi-finished product to produce a semi-finished product which is received in the respective cartridge;
a machine configured to machine and sharpen an end of the cut semi-finished product; and
a stud-shooter configured to shoot the sharpened semi-finished product from the respective cartridge into the substrate or the textile of the core structure;
wherein the conveyor is configured to convey each of the plurality of cartridges to the stud-shooter.

6. The device according to claim 5 , wherein the stud-shooter comprises a stud which is arranged movably in a longitudinal direction of the semi-finished product and has a diameter at an end thereof facing the semi-finished product which corresponds substantially to a diameter of an end of the semi-finished product facing the stud.

7. The device according to claim 5 , wherein the cartridges are arranged adjacent one another in an endless loop.

8. The device according to claim 5 , wherein the stud-shooter comprises an electric, pneumatic and/or hydraulic drive.

9. The method according to claim 1 , wherein the component is a core composite component of an aircraft or spacecraft.

10. The method according to claim 2 , wherein the component is a core composite component of an aircraft or spacecraft.

11. The device according to claim 5 , wherein the component is a core composite component of an aircraft or spacecraft.

12. The method according to claim 1 , wherein the machine comprises a machining means.

13. The method according to claim 2 , wherein the machine comprises a machining means.
