Abstract

Die vorliegende Erfindung betrifft insbesondere ein Verfahren zum Anbringen bzw. Herstellen eines geschlossenen Deckbandes (1) an die/den stirnseitigen freien Enden (2) von nebeneinander angeordneten Schaufelblättern (3) einer Laufbeschaufelung einer Turbinenstufe einer Turbine, wobei ein Band aus einem Faserwerkstoff auf die stirnseitigen freien Enden (2) der Schaufelblätter (3) gewickelt wird, ein Matrixwerkstoff in den Faserwerkstoff des aufgewickelten Bandes infiltriert wird und der entstehende Faserverbundwerkstoff ausgehärtet wird. Ferner betrifft die Erfindung zwei weitere Verfahren zum Anbringen/Herstellen eines geschlossenen Deckbandes (1) an die/den stirnseitigen freien Enden (2) von nebeneinander angeordneten Schaufelblättern (3) einer Laufbeschaufelung einer Turbinenstufe einer Turbine sowie eine Laufbeschaufelung für eine Turbine, aufweisend eine Vielzahl nebeneinander angeordneter Schaufelblätter (3), wobei die Schaufelblätter (3) aus einem Faserverbundwerkstoff ausgebildet sind.
