1. Vindmøllevinge (14) af fiberarmeret polymer, kendetegnet ved, at den er opdelt i en indre endedel (15), som omfatter vingeroden, og som i det væsentlige er fremstillet af glasfiberarmeret polymer, og en ydre endedel (17), som omfatter vingespidsen, og som i det væsentlige er fremstillet af kulfiberarmeret polymer. 2. Vindmøllevinge (14)ifølge krav 1,kendetegnet ved, at den ydre endedel (17) udgør mellem 25% og 50% af hele vingens (14) længde. 3. Vindmøllevinge (14) ifølge krav 1 eller 2, kendetegnet ved, at den ydre endedel (17) modsat vingetippen omfatter en overgangszone (16), hvor kulfibrene gradvist afløses af glasfibre. 4. Vindmøllevinge (14) ifølge krav 3, hvor overgangszonen (16) har en længde på mellem 0,5 og 1 meter. 5. Vindmøllevinge (14) ifølge krav 3 eller 4, kendetegnet ved, at de to typer fibre er således fordelt i polymermaterialet, at kulfibre eller kulfiberbundter (1) med forskellige længder forløber fra en første ende af overgangszonen (II), og glasfibre eller glasfiberbundter (II) forløber fra den modsatte ende af overgangszonen (II). 6. Vindmøllevinge (14) ifølge krav 3 eller 4, kendetegnet ved, at overgagszonen (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 kulfibre (6) på den ene side af grænsefladen og glasfibre (7) på den anden side af grænsefladen, og hvor de enkelte fiberlags grænseflader (10) er forskudt i forhold til hinanden i vingens (14) længderetning. 7. Vindmøllevinge ifølge krav 6, hvor grænsefladerne (11) er savtakformede set i snit parallelt med fiberlagene (3, 4, 5). 8. Vindmøllevinge ifølge krav 7, hvor de savtakformede grænsefladers (11) spidser (12) er forskudt i forhold til hinanden i vingens (14) tværretning.
