## Abstract

A method for producing a composite component, which has a first section and a second section connected to the first section, the first section including a metallic material, the second section including a plastic, the first section having a first base region and projections provided on the first base region, and the projections provided on the first base region being anchored in the second section in order to bring about the connection between the first section and the second section, includes: manufacturing the first base region of the first section; creating the projections directly on the first base region by way of an additive manufacturing method; and connecting the second section to the first section.

## Claims

### Claim 1

A method for producing a composite component having a first section and a second section connected to the first section, wherein the first section comprises a metallic material, wherein the second section comprises a plastic, wherein the first section has a first base region and projections provided on the first base region, and wherein the projections provided on the first base region are anchored in the second section in order to bring about the connection between the first section and the second section, the method comprising:
manufacturing the first base region of the first section;
creating the projections directly on the first base region by way of an additive manufacturing method; and
connecting the second section to the first section.

### Claim 2 (depends on 1)

The method as claimed in claim 1, wherein the connecting the second section to the first section comprises positioning the first section in a tool for manufacturing the second section, and producing the second section in the tool on the first section by primary forming and/or secondary forming.

### Claim 3 (depends on 1)

The method as claimed in claim 1, wherein the second section is manufactured, and then, wherein the connecting the second section to the first section comprises connecting the second section to the first section by way of a pressing process.

### Claim 4 (depends on 3)

The method as claimed in claim 3, wherein prior to the pressing process, the first section or the second section or both the first section and the second section are heated at least regionally in order to bring about melting of the material of the second section in the region of the connection.
