## Abstract

Methods for fastening or coupling dissimilar materials to each other may include providing a first component with a first through hole and a second component with a second through hole that is at least partly aligned with the first through hole. A mixture including a first material and a second material may be injected into the aligned through holes of the first component and the second component. The mixture of the first material and the second material may expand in the through holes, e.g., due to a chemical reaction, thereby connecting the first component and the second component together.

## Claims

### Claim 1

A fastening method for components, comprising:
providing a first component with a first through hole, the first component being planar and the first through hole being circular;
providing a second component with a second through hole, the second component being planar, wherein the first and second components are independent and separate from each other;
aligning the first through hole of the first component and the second through hole of the second component to form an aligned through hole, the aligned through hole being a cylindrical cavity formed within the first component and the second component, wherein the first through hole and the second through hole have different sizes;
inserting a first material into the aligned through hole;
inserting a second material into the aligned through hole;
mixing, within the aligned through hole, the first material with the second material; and
allowing the mixture of the first material and the second material to expand in the aligned through hole to form a cap bolt with an area greater than an area of the aligned through hole, such that the cap bolt connects the first component and the second component together, wherein the first material includes a first kind of glue and the second material includes a second kind of glue such that the first kind of glue and the second glue when mixed together in the aligned through hole cause a chemical reaction to form the cap bolt and a hardness of the cap bolt is lower than a hardness of the first component or a hardness of the second component; and, wherein the first component and the second component are made of dissimilar metal materials; and
the first component and the second component are arranged such that an outer surface of the first component has a contact with an outer surface of second component.

### Claim 2 (depends on 1)

The method of claim 1, wherein:
the first material comprises isocyanate, and the second material comprises polyol.

### Claim 3 (depends on 1)

The method of claim 1, wherein:
the expansion of the mixture of the first material and the second material forms an outer edge with an area greater than an area of the through holes.

### Claim 4 (depends on 3)

The method of claim 3, wherein:
the fastening method for components is used for connecting two components of an electric vehicle.

### Claim 5 (depends on 1)

The method of claim 1, wherein the mixture of the first material and the second material expands in the aligned through hole due to a chemical reaction.

### Claim 6 (depends on 1)

The method of claim 1, further comprising hardening the expanded mixture, wherein the hardened expanded mixture is softer than a cladding layer provided on the first or second components.
