Abstract

A method of joining multiple components is disclosed. The method includes arranging a first component having a first surface, an opposing second surface, and a feature, in contact with a second component having a first surface, an opposing second surface, and defining an aperture. When so arranged, the first surface of the first component is adjacent to the second surface of the second component. The method also includes positioning a fastener on the first surface of the second component and in contact with the feature of the first component, such that at least a portion of the fastener overlaps the aperture on the first surface of the second component. The method additionally includes abutting and fusing the fastener to the feature of the first component to thereby affix the first component to the second component.

First claim

The invention claimed is:

1. A method of joining multiple components, the method comprising:
arranging a first component having a first surface, an opposing second surface, a feature, and a spacer projecting from the first surface and separated by a portion of the first surface from the feature, such that each of the feature and the spacer is in contact with a second component, wherein:
the second component has a first surface, an opposing second surface, and defines an aperture, such that the first surface of the first component is adjacent to the second surface of the second component

positioning a one-sided rivet on the first surface of the second component and in contact with the feature of the first component, such that at least a portion of the fastener overlaps the aperture on the first surface of the second component, wherein the one-sided rivet is a disc, and the feature of the first component is a post
extending the post through the aperture and completely through the second component
arranging entirety of the disc on top of the post and above the second component; and
abutting and fusing the disc to the post and thereby affixing the first component to the second component via the fastener.

2. The method of claim 1 , wherein the first component is constructed from plastic and the second component is constructed from metal.

3. The method of claim 2 , wherein the plastic is a carbon fiber reinforced thermoplastic (CFRTP) and the metal is steel.

4. The method of claim 2 , wherein the fastener is constructed from plastic.

5. The method of claim 1 , wherein said fusing the fastener to the feature of the first component includes welding.

6. The method of claim 5 , wherein said welding is ultrasonic welding or friction welding.

7. The method of claim 1 , wherein the spacer is molded into the first surface the first component.

8. The method of claim 1 , wherein arranging the first component in contact with the second component includes affixing the first component to the second surface of the second component via an adhesive and generating a gap for the adhesive via the spacer.

9. A multiple-component assembly comprising:
a first component having a first surface, an opposing second surface, a feature, and a spacer projecting from the first surface and separated by a portion of the first surface from the feature;
a second component having a first surface and an opposing second surface, and defining an aperture, wherein the second component is arranged in contact with the first component such that the first surface of the first component is adjacent to the second surface of the second component; and
a one-sided rivet positioned on the first surface of the second component abutted and fused to the feature of the first component, such that at least a portion of the fastener overlaps the aperture on the first surface of the second component, such that the fastener affixes the first component to the second component;
wherein the one-sided rivet is a disc, and the feature of the first component is a post extending through the aperture and completely through the second component, and abutting the disc, and wherein entirety of the disc is arranged on top of the post and above the second component.

10. The multiple-component assembly of claim 9 , wherein the first component is constructed from plastic and the second component is constructed from metal.

11. The multiple-component assembly of claim 10 , wherein the plastic is a carbon fiber reinforced thermoplastic (CFRTP) and the metal is steel.

12. The multiple-component assembly of claim 10 , wherein the fastener is constructed from plastic.

13. The multiple-component assembly of claim 9 , wherein the fastener is fused to the feature of the first component via welding.

14. The multiple-component assembly of claim 13 , wherein the welding is ultrasonic welding or friction welding.

15. The multiple-component assembly of claim 9 , wherein the spacer is molded into the first surface of the first component.

16. The multiple-component assembly of claim 9 , wherein the first component is affixed to the second surface of the second component via an adhesive and a gap is generated for the adhesive via the spacer.
