Description

PATENTKRAV 1. Fremgangsmåde til fremstilling af en vindmøllevinge af kompositmaterialer omfattende fiberarmeret matrixmateriale, kendetegnet ved, at vingen fremstilles i ét stykke i en lukket form hvor der tilvejebringes: en formkeme med en fleksibel ydre kernedel og en indre fast eller formbar kernedel, og ydre formparter der er indrettet for at lukke om formkemen med dannelse af et formhulrum derimellem, at kompositmaterialeme og eventuelle kemeindlæg oplægges på en ydre formpart og/eller på formkemen, at de ydre formparter lukkes om formkemen og det i formhulrummet anbragte kompo-sitmateriale, at kompositmaterialet hærdes, at de ydre formparter fjernes, og at formkemen udtages fra den formstabile vinge før eller efter fjernelse af de ydre formparter. 2. Fremgangsmåde ifølge krav 1,kendetegnet ved, at der ved oplægning af kompositmaterialet anvendes en del af det nødvendige matrixmateriale i tilknytning til armeringsfibrene og at yderligere matrixmateriale tilføres efter lukning af formen. 3. Fremgangsmåde ifølge krav 1 eller 2, kendetegnet ved, at kompositmaterialet oplægges om et kernemateriale for dannelse af vingen i en sandwichkonstruktion, at kernematerialet anvendes til evakuering og flydning ved vakuumformning af vingen idet formhulrummet sættes under vakuum hvorved luft evakueres samtidig med at kompositmaterialer og evt. kemeindlæg sammenpresses mod indersiden af de ydre formparter på grund af formkemens fleksible ydre kernedel og at matrixmaterialet injiceres efter formhulrummet er vakuumdannet. 4. Fremgangsmåde ifølge krav 3, kendetegnet ved, at matrixmaterialet injiceres via en kanal der befinder sig ved en vertikal underside af formhulrummet og med et reguleret flow for styring af en opadskridende flydefront af matrixmaterialet med henblik på at undgå indeslutning af luft i formhulrummet. 5. Fremgangsmåde ifølge krav 3 og 4, kendetegnet ved, at der på en første ydre formpart oplægges et ydre lag fibermateriale, der strækker sig udenfor en sidekant af formhulrummet, at der ved nævnte sidekant placeres flyderør for injektion af matrix-materiale, at et lag af kernematerialet og eventuelle andre kernedele placeres, at der oplægges er indre lag fibermateriale, der strækker sig udenfor nævnte sidekant, at formkemen anbringes i de oplagte lag, at et indre lag fibermateriale, at det udstræk-kende fibermateriale foldes ind over formkemen og flyderøret, at et lag kernemateriale og et ydre lag fibermateriale oplægges på formkemen, at den anden ydre formpart placeres i tæt anlæg mod den første ydre formpart, at vakuum påføres formhulrummet og at matrixmaterialet injiceres via flyderøret. 6. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, kendeteg-n e t ved, at kemeindlæg er indlagt mellem lagene af fibermateriale og afformes sammen med kompositmaterialet for fremstilling af en vinge hvor sådanne indlæg udgør konstruktionselementer i den færdige vinge. 7. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, kendeteg-n e t ved, at der anvendes termohærdning og at temperaturen i vingens kompositmate-riale ændres under hærdningen ved anvendelse af et temperaturreguleringssystem i en eller flere af formparteme. 8. Fremgangsmåde ifølge et hvilket som helst af kravene 3-7, kendetegnet ved, at kernematerialet er forsynet med gennemgående passager, der benyttes som flydeve-je for matrixmateriale mellem de to lag ftbermateriale. 9. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, kendeteg-n e t ved, at injicering af matrixmaterialet afsluttes når flydende matrixmateriale presses ud af åbninger ved den opefter vendende sidekant af vingen. 10. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, kendeteg-n e t ved, at formkemen tilvejebringes i flere separate dele.
