Abstract

The invention provides a stiffening element, in particular for a shell component of an aircraft or spacecraft, which has a stiffening profile part and a foot part. The stiffening profile part is in this case composed of a lightweight metal material, and the foot part is composed of a material which is highly resistant to corrosion. A method is also provided for production of a stiffening element, in particular for a shell component of an aircraft or spacecraft. A stiffening profile semi-finished product is first of all produced from a lightweight metal material, and a foot part is produced from a material which is highly resistant to corrosion. The foot part and the stiffening profile semi-finished product are then integrally connected. The stiffening profile semi-finished product together with the foot part is then subjected to machining to form an intended shape for the stiffening element.
