Abstract:
1. A method for producing a core structure, the method comprising: spacing apart a first and a second core structure layer positioning the first core structure layer at a defined distance to produce a cavity therebetween, wherein the first core structure layer and the second core structure layer have an extension direction; moving a spacer element between the first and second core structure layers in the direction of the extension direction, wherein the spacer element spans substantially across the first and second core structure layers and is configured to space the first and second core structure layers apart from one another by a predetermined distance therebetween; introducing a reinforcement element into the cavity behind the spacer element in the extension direction; wherein the reinforcement element, the first core structure layer, and the second core structure layer form a self-supporting core structure.
