A HOLLOW ELEMENT FOR ATTACHMENT TO A COMPONENT COMPRISING A COMPOSITE MATERIAL

摘要

A hollow element such as a hollow rivet or a nut element for attachment to a component consisting of a composite material such as a fiber reinforced plastic part or a fabric reinforced plastic part is presented. The element has a flange part and a shaft part extending away from the flange part and/or a rivet section, wherein the rivet section, if present, can also be formed at the free end of the shaft part, with the a hollow element furthermore having a central passage, which is optionally provided with a thread cylinder. The hollow element is used in combination with an auxiliary tip which is either inserted from the flange side of the element through the passage, or from the side of the free end of the shaft part 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 free end of the hollow shaft part of the element, or the free end of the rivet section, has a conically converging form which is matched to the conical shape of the auxiliary tip that is used.
