Patent number: 8127450Abstract: The present invention provides a method of producing a construction, in particular a sandwich construction for the aeronautical and aerospace fields, comprising the following steps. A heating material is initially applied on one side of a core construction material. In a further step a reinforcing element is introduced into the core construction material and the heating material in such a way that the reinforcing element extends through the core construction material and the heating material and has a portion which projects beyond the heating material. The heating material is then heated to soften the projecting portion at least in regions and said projecting portion is subsequently deformed using the softened region as a pivot point to engage the core construction material from behind and to form the construction. This method is distinguished in particular by the fact that it allows the portions to be heated substantially simultaneously, and not sequentially as in the state of the art.Type: GrantFiled: January 29, 2009Date of Patent: March 6, 2012Assignee: Airbus Operations GmbHInventors: Hans-Jurgen Weber, Gregor Christian Endres
