Claims (15)
1. Fremgangsmåde til fremstilling af en rotorblad-konstruktionsdel til et vindenergianlæg, hvor rotorblad-konstruktionsdelen har et i forvejen fremstillet hovedbånd (32), hvilken fremgangsmåde omfatte de trin: • at der tilvejebringes en støbeform (10), som har en bladrodsende (14) og en bladyderende (18), • at der indlægges mindst et rodforstærkningslag (28) af et fibermateriale i støbeformen (10), • at man anbringer det i forvejen fremstillede hovedbånd (32) på det mindst ene ydre rodforstærkningslag (28), idet hovedbåndet (32) ikke kan mættes med et flydende plastmateriale, • at man i støbeformen anbringer mindst et indre rodforstærkningslag (38) af fibermateriale på hovedbåndet (32) i støbeformen (10), • at man lukker støbeformen (10), • at man udsuger luft fra støbeformen (10) gennem mindst en udsugningskanal, som er indrettet i en sideværts afstand fra hovedbåndet (32), • at man udstøber et flydende plastmateriale via en første støbekanal (12), som har et antal udløbsåbninger under hovedbåndet (32), og • at man udstøber et flydende plastmateriale via en anden støbekanal (46), som har et antal udløbsåbninger oven over hovedbåndet (32).
2. Fremgangsmåde ifølge krav 1, kendetegnet ved, at udløbsåbningerne i den første støbekanal (12) er indrettet midt under hovedbåndet (32) og anordnet fordelt over et længdesnit i støbeformen (10).
3. Fremgangsmåde ifølge krav 1 eller 2, kendetegnet ved, at der i længdesnittet er anordnet flere rodforstærkningslag (28) oven på hinanden, og som har en totaltykkelse på 1 mm eller mere.
4. Fremgangsmåde ifølge krav 2 eller 3, kendetegnet ved, at længdesnittet kun strækker sig over en del af hovedbåndets (32) totallængde.
5. Fremgangsmåde ifølge krav 1 til 4, kendetegnet ved, at flere indre og/eller ydre rodforstærkningslag (28, 38) er anordnet oven på hinanden, hvilke lags totaltykkelse, set i et længdesnit i vindenergianlæg-rotorbladskonstruktionen, formindskes med stigende afstand fra bladrodens ende.
6. Fremgangsmåde ifølge krav 1 til 5, kendetegnet ved, at en tykkelse af hovedbåndet (32), set i et længdesnit i vindenergianlæg-rotorbladskonstruktionsde-len, forøges med stigende afstand fra den ved bladroden værende ende.
7. Fremgangsmåde ifølge et af kravene 1 til 6, kendetegnet ved, at støbningen ved hjælp af den anden støbekanal (46) først påbegyndes efter udløbet af en tidsperiode efter begyndelsen af støbningen via en første støbekanal (12).
8. Fremgangsmåde ifølge krav 7, kendetegnet ved, at den nævnte tidsperiode er således valgt, at det gennem den første støbekanal (12) udstøbte plastmateriale fordeles under hovedbåndet (32), når udstøbningen gennem den anden støbekanal (46) påbegyndes.
9. Fremgangsmåde ifølge krav 1 til 8, kendetegnet ved, at man før man indlægger det mindst ene ydre rodforstærkningslag (28) indlægger et i forvejen fremstillet rodindlæg (20) ved den ved bladrodsiden værende ende af støbeformen (10).
10. Fremgangsmåde ifølge krav 9, kendetegnet ved, at rodindlægget (20) og hovedbåndet (32) i et længdesnit i vindenergianlæg-rotorbladskonstruktionsde-len er anordnet overlappende.
11. Fremgangsmåde ifølge krav 9 eller 10, kendetegnet ved, at rodindlægget (20) i det længdeafsnit, hvori det er anordnet, så at det overlapper hovedbåndet (32), bliver tyndere og tyndere med stigende afstand fra den ved bladrodsiden værende ende.
12. Fremgangsmåde ifølge et af kravene 9 til 11, kendetegnet ved, at der mellem rodindlægget (20) og hovedbåndet (32) er indlagt et fordelingsmedium (26).
13. Fremgangsmåde ifølge et af kravene 1 til 12, kendetegnet ved, at yderligere lag af et fibermateriale indlægges i formen, hvilke lag danner de ydre flader på vindenergianlægs-rotorbladkonstruktionsdelen.
14. Fremgangsmåde ifølge krav 13, kendetegnet ved, at de yderligere lag sideværts grænser op til hovedbåndet (32), og at hovedbåndet (32) ved siden har tilslutningsafsnit, hvormed de nævnte yderligere lag er forbundet.
15. Fremgangsmåde ifølge krav 13 eller 14, kendetegnet ved, at de yderligere lag grænser op til en side, som er langt fra bladrodsenden, og at rodindlægget (20) ved nævnte side har et tilslutningsafsnit, hvormed de yderligere lag er forbundet.
