Abstract

According to one aspect, the present disclosure provides a system for manufacturing transition structures including fiber threads embedded within a metal component. The system may include a supply of base sheet metal. The system may include a conveyor supported on a plurality of rollers and configured to move the base sheet metal in a production direction. The system may include a plurality of stages arranged in the production direction. Each stage may include a channel forming device configured to form a channel in the base sheet metal, a fiber inserting device configured to insert a portion of a fiber material into the channel, and one or more ultrasonic welders configured to consolidate a layer of metal foil over the fiber. The disclosure includes methods of using the system to produce transition structures and reinforced components.

First claim

What is claimed is:

1. A system for manufacturing reinforced structures, the system comprising:
a first reinforcement source that feeds a first reinforcement layer on a base sheet metal;
a first channel forming device positioned upstream of the first reinforcement source configured to form a channel in the base sheet metal, wherein the first reinforcement source comprises a first fiber inserting device that is configured to insert a portion of a fiber material into the channel and a metal roll that is configured to feed a layer of metal foil over the portion of the fiber material to at least partially form the first reinforcement layer;
a first ultrasonic welder positioned downstream of the first reinforcement source that secures the first reinforcement layer to the base sheet metal;
a second reinforcement source positioned downstream of the first reinforcement source that feeds a second reinforcement layer on the first reinforcement layer; and
a second ultrasonic welder positioned downstream of the second reinforcement source that secures the second reinforcement layer to the first reinforcement layer.

2. The system of claim 1 , further comprising:
a second channel forming device positioned upstream of the second reinforcement source and is configured to form a channel in the first reinforcement layer; wherein the second reinforcement source comprises a second fiber inserting device that is configured to insert a second portion of a fiber material into the channel formed by the second channel forming device and a metal roll that is configured to feed a layer of metal foil over the second portion of the fiber material to at least partially form the second reinforcement layer.

3. The system of claim 1 , further comprising a conveyor that is supported on a plurality of rollers, wherein the conveyor is configured to move the base sheet metal in a production direction.

4. The system of claim 3 , wherein a first roller is positioned along the conveyor opposite the first ultrasonic welder, and a second roller is positioned along the conveyor opposite the second ultrasonic welder.

5. The system of claim 4 , wherein at least one of the first roller or the second roller includes a central support surface and side constraints that constrain the base sheet metal against movement transverse to the production direction.

6. The system of claim 1 , further comprising a third ultrasonic welder positioned on an opposite side of the base sheet metal to the first ultrasonic welder, wherein the third ultrasonic welder is driven out of phase amplitude wise with the first ultrasonic welder.

7. The system of claim 1 , further comprising:
a third reinforcement source that feeds a third reinforcement layer on the base sheet metal a first distance apart from the first reinforcement layer; and
a third ultrasonic welder positioned downstream of the third reinforcement source that secures the third reinforcement layer to the base sheet metal.

8. The system of claim 1 , wherein the first reinforcement layer comprises a different composition than the second reinforcement layer.

9. The system of claim 1 , wherein the metal foil of the first reinforcement layer is a different composition than the metal foil of the second reinforcement layer.

10. The system of claim 2 , wherein the fiber material of the first reinforcement layer comprises a different composition than the fiber material of the second reinforcement layer.

11. The system of claim 7 , wherein the first reinforcement layer comprises a different composition than the third reinforcement layer.

12. A system for manufacturing reinforced structures, the system comprising:
a first reinforcement source that feeds a first reinforcement layer on a base sheet metal;
a first ultrasonic welder positioned downstream of the first reinforcement source that secures the first reinforcement layer to the base sheet metal;
a second reinforcement source positioned downstream of the first reinforcement source that feeds a second reinforcement layer on the first reinforcement layer;
a second ultrasonic welder positioned downstream of the second reinforcement source that secures the second reinforcement layer to the first reinforcement layer; and
a third ultrasonic welder positioned on an opposite side of the base sheet metal to the first ultrasonic welder, wherein the third ultrasonic welder is configured to be driven out of phase amplitude wise with the first ultrasonic welder.

13. The system of claim 12 , further comprising a conveyor that is supported on a plurality of rollers, wherein the conveyor is configured to move the base sheet metal in a production direction.

14. The system of claim 12 , further comprising:
a third reinforcement source that feeds a third reinforcement layer on the base sheet metal a first distance apart from the first reinforcement layer; and
a fourth ultrasonic welder positioned downstream of the third reinforcement source that secures the third reinforcement layer to the base sheet metal.

15. The system of claim 14 , wherein the first reinforcement layer comprises a different composition than the third reinforcement layer.

16. The system of claim 12 , wherein the first reinforcement layer comprises a different composition than the second reinforcement layer.

17. The system of claim 12 , wherein the metal foil of the first reinforcement layer is a different composition than the metal foil of the second reinforcement layer.

18. A method for manufacturing reinforced structures, the method comprising:
forming a channel in a base sheet metal at a first channel forming device;
feeding a first reinforcement layer on the base sheet metal from a first reinforcement source positioned downstream of the first channel forming device, wherein the first reinforcement source comprises a first fiber inserting device that is configured to insert a portion of a fiber material into the channel and a metal roll that is configured to feed a layer of metal foil over the portion of the fiber material to at least partially form the first reinforcement layer;
securing the first reinforcement layer to the base sheet metal at a first ultrasonic welder positioned downstream of the first reinforcement source;
feeding a second reinforcement layer on the first reinforcement layer at a second reinforcement source positioned downstream of the first reinforcement source; and
securing the second reinforcement layer to the first reinforcement layer at a second ultrasonic welder positioned downstream of the second reinforcement source.

19. The method of claim 18 , further comprising:
forming a channel in the first reinforcement layer at a second channel forming device positioned upstream of the second reinforcement source, wherein the second reinforcement source comprises a second fiber inserting device that is configured to insert a second portion of a fiber material into the channel formed by the second channel forming device and a metal roll that is configured to feed a layer of metal foil over the second portion of the fiber material to at least partially form the second reinforcement layer.

20. The method of claim 18 , further comprising:
feeding a third reinforcement layer on the base sheet metal a first distance apart from the first reinforcement layer at a third reinforcement source; and
securing the third reinforcement layer to the base sheet metal at a third ultrasonic welder positioned downstream of the third reinforcement source.
