Abstract

Die Erfindung betrifft einen Koppelbolzen (1) zum Koppeln von zwei oder mehreren Turbinenschaufeln (2), wobei die Koppelbolzen (1) zumindest teilweise aus Faserverbundwerkstoff bestehen. Durch die zumindest teilweise Ausbildung aus Faserverbundwerkstoff kann das Gewicht der Koppelbolzen (1) gegenüber im Stand der Technik deutlich herabgesetzt werden.
