Claims (22)
1. Vinge til en vindmølle, hvori mindst en tredjedel af længden målt fra tip til nav af vingen omfatter et lag (1,2) langs en ydre periferi af vingens tværsnit kendetegnet ved, at laget (1,2) i det mindste delvis udgøres af et antal præfabrikerede pultruderede strimler (2) af et fibrøst kompositmateriale og strimler fremstillet af et træmateriale anbragt i bestemt rækkefølge langs den ydre periferi.
2. Vinge ifølge krav 1, hvorved strimlerne i det ydre lag (1,2) er føjet sammen ved brug af harpiksinfusion.
3. Vinge ifølge krav 2, hvorved strimlerne i det ydre lag (1,2) er føjet sammen ved vakuuminfusion af en harpiks.
4. Vinge ifølge et af kravene 1-3, hvorved i det mindst nogle af de præfabrikerede pultruderede strimler (2) udgøres af hule rør fremstillet af et fibrøst kompositmateriale.
