Figure DK200200425AD00031
1. Vindmøllevinge af fiberarmeret polymer omfattende en første type fibre (1,3,6) med en første stivhed og en første brudforlængelse og en anden type fibre (2, 5, 7) med en anden stivhed og en anden brudforlængelse, kendetegnet ved, at de to typer fibre er fordelt i polymermatrixen, og at mængdeforholdet set i et tværsnit vinkelret på vingens længderetning mellem mængden af de to typer fibre varierer kontinuerligt i vingens længderetning. 2. Vindmøllevinge ifølge krav 1, hvor den første type fibre er glasfibre (1), og den anden type fibre er kulfibre (2). 3. Vindmøllevinge ifølge krav 1 eller 2,kendetegnet ved, at mængdeforholdet stiger eller falder kontinuerligt fra et første niveau til et andet niveau. 4. Vindmøllevinge ifølge et af kravene 1-3, kendetegnet ved, at mængdeforholdet varierer kontinuerligt i en overgangszone (II), der har en længde, som er mindre end vingens længde. 5. Vindmøllevinge ifølge krav 4, kendetegnet ved, at overgangszonen ligger mellem en første zone (I) og en anden zone (III), der begge har et i det væsentlige ensartet mængdeforhold mellem de to typer fibre. 6. Vindmøllevinge ifølge krav 5, hvor overgangszonen (II) har en længde på mellem 0,5 og 1 m. 7. Vindmøllevinge ifølge krav 4, hvor vingen er opdelti overgangszonen (II), der omfatter vingeroden, og en yderligere zone, der omfatter den øvrige del af vingen. 8. Vindmøllevinge ifølge krav 4, hvor vingen er opdelt i overgangszonen (II), der omfatter vingetippen, og en yderligere zone, der omfatter den øvrige del af vingen. 9. Vindmøllevinge ifølge et af kravene 4-8, kendetegnet ved, at fibre eller fiberbundter af den første type (1) med forskellige længder forløber fra en første ende af overgangszonen (II), og fibre eller fiberbundter af den type (2) forløber fra den modsatte ende af overgangszonen (Π). 10. Vindmøllevinge ifølge krav 4, kendetegnet ved, at overgangszonen (II) består af et laminat af flere fiberlag (6,7), hvor hvert fiberlag ved en position i længderetningen har en grænseflade (10), idet fiberlaget omfatter fibre af den første type (6) på den ene side af grænsefladen og fibre af den anden type (7) på den anden side af grænsefladen, og hvor de enkelte fiberlags grænseflader (10) er forskudt i forhold til hinanden i vingens længderetning. 11. Vindmøllevinge ifølge krav 10, hvor grænsefladerne (11) er savtakformede set i et snit parallelt med fiberlagene (3, 4, 5). 12. Vindmøllevinge ifølge krav 11, hvor de savtakformede grænsefladers (11) spidser (12) er forskudt i forhold til hinanden i vingens tværretning. 13. Præfabrikeret overgangsskalemne til fremstilling af skallen til en vindmøllevinge, hvilket overgangsskalemne består af fiberarmeret polymer omfattende en første type fibre (1,3, 6) med en første stivhed og en første bmdforlængelse og en anden type fibre (2, 5, 7) med en anden stivhed og en anden brudforlængelse, kendetegnet ved, at de to typer fibre er fordelt i polymermatrixen, og at mængdeforholdet set i et tværsnit vinkelret på vingens længderetning mellem mængden af de to typer fibre varierer kontinuerligt i overgangsskalemnets længderetning.
