Abstract
A method for the attachment of a hollow element such as a hollow rivet or a nut element to a component consisting of a composite material, with the element having a flange part and a shaft part or rivet section extending away from the flange part, wherein a rivet section can also be formed at the free end of a shaft part. The hollow element has a central passage which is optionally provided with a thread cylinder. In the method an auxiliary tip is either passed from the flange side of the element remote from the shaft part and/or the rivet section through the passage or is introduced from the side of the free end of the shaft part and/or of the rivet section into the passage such that a conically converging region of the auxiliary tip projects from the free end of the shaft part or of the rivet section. The hollow element is pressed with the tip to the fore against the component and the tip is pressed through the component until the component comes into engagement with the side of the flange part adjacent to it and the tip has produced a hole in the component.
