Ushicilelo lwe-3D lweencakuba ze-thermoplastic lwenza ukuwelda kwe-thermal kunye nokuphucula ukusebenziseka kwakhona, kunika amandla okunciphisa ubunzima be-blade ye-turbine kunye neendleko ubuncinane nge-10%, kunye nexesha lomjikelo wemveliso nge-15%.

Iqela leNational Renewable Energy Laboratory (NREL, Golden, Colo., US) abaphandi, elikhokelwa yiNREL injineli ephezulu yetekhnoloji yomoya uDerek Berry, bayaqhubeka nokuqhubela phambili ubuchule babo benoveli bokwenza iiblade zeinjini yomoya eziphucukileyo.ukuqhubela phambili indibaniselwano yaboyokwenziwa ngokutsha kwe-thermoplastics kunye ne-additive production (AM). Inkqubela phambili yenzeke ngenkxaso-mali evela kwi-Ofisi yoMveliso ekwiSebe lezaMandla ekwiSebe laseMelika ekwi-Advanced Manufacturing Office - amabhaso ayilelwe ukuvuselela iteknoloji entsha, ukuphucula imveliso yamandla kwimveliso yase-US kunye nokwenza ukuveliswa kweemveliso ezikumgangatho ophezulu.

Namhlanje, uninzi lwamaphiko einjini yomoya anoyilo olufanayo lweclamshell: Izikhumba ezimbini zefiberglass blade zidityaniswe kunye nokuncamathelisa kwaye zisebenzisa into enye okanye ezininzi ezidityanisiweyo eziqinisayo ezibizwa ngokuba yi-shear webs, inkqubo elungiselelwe ukusebenza kakuhle kule minyaka ingama-25 idlulileyo. Nangona kunjalo, ukwenza ii-wind turbine blades zibe khaphukhaphu, zide, zingabizi kakhulu kwaye zisebenze ngakumbi ekubambeni amandla omoya - ukuphuculwa okubalulekileyo kwinjongo yokusika ukukhutshwa kwegesi ye-greenhouse ngokuyinxenye ngokunyusa imveliso yamandla omoya - abaphandi kufuneka bacinge ngokutsha nge-clamshell eqhelekileyo, into eyiyo. eyona nto iphambili yeqela le-NREL.

Ukuqala, iqela le-NREL lijolise kwizinto eziphathekayo ze-resin matrix. Uyilo lwangoku luxhomekeke kwiinkqubo ze-thermoset resin ezifana ne-epoxies, i-polyester kunye ne-vinyl esters, iipolymers ezithi, xa sele zinyangisiwe, zidibanisa njengebrambles.

Nje ukuba uvelise iblade ngenkqubo ye-thermoset resin, awukwazi ukuyibuyisela umva inkqubo,” utshilo uBerry. “Kwakhona kwenza ibladekunzima ukurisayikilisheka.”

Ukusebenza kunyeIziko leNdlela eNtsha yokuVeliswa kweZidibaniso eziPhambili(IACMI, Knoxville, Tenn., US) kwi-NREL's Composites Manufacturing Education and Technology (CoMET) Facility, iqela le-multi-institution liphuhlise iinkqubo ezisebenzisa i-thermoplastics, leyo, ngokungafaniyo nezixhobo ze-thermoset, inokufudumeza ukuhlula iipolymers zangaphambili, ezivumela ukuphela. -of-life (EOL) recyclability.

Iinxalenye ze-Thermoplastic blade nazo zinokudityaniswa kusetyenziswa inkqubo ye-thermal welding enokuphelisa imfuno yokuncamathelisa - ehlala inzima kwaye iyimpahla ebizayo - ngakumbi ukomeleza ukuphinda kusetyenziswe iblade.

"Ngamacandelo amabini e-thermoplastic blade, unakho ukukwazi ukuwahlanganisa kwaye, ngokusetyenziswa kobushushu kunye noxinzelelo, uzidibanise," utshilo uBerry. "Awunakuyenza loo nto ngezinto ze-thermoset."

Ukuqhubela phambili, i-NREL, kunye namaqabane eprojekthiTPI Composites(Scottsdale, Ariz., US), Izisombululo zobuNjineli boNgezelelweyo (Akron, Ohio, US),Ingersoll Machine Tools(I-Rockford, Ill., US), iYunivesithi yaseVanderbilt (i-Knoxville) kunye ne-IACMI, iya kuphuhlisa izakhiwo ezingundoqo ze-blade ukwenzela ukuba ukuveliswa kwexabiso eliphezulu lokusebenza okuphezulu, ama-blades amade kakhulu - ngaphezu kweemitha ezili-100 ubude - eziphantsi kakhulu. ubunzima.

Ngokusebenzisa ushicilelo lwe-3D, iqela lophando lithi linokuvelisa iintlobo zoyilo olufunekayo ukwenza iiblade ze-injini ye-injini zibe zangoku ngobunjineli obuphezulu, ii-cores ezimile okwenetha zoxinaniso olwahlukeneyo kunye neejometri phakathi kwezikhumba ze-injini ye-injini. Izikhumba ze-blade ziya kufakwa kusetyenziswa inkqubo ye-resin thermoplastic.

Ukuba bayaphumelela, iqela liya kunciphisa ubunzima be-turbine blade kunye neendleko nge-10% (okanye ngaphezulu) kunye nexesha lokujikeleza kwemveliso ubuncinane kwi-15%.

Ukongeza kwiIbhaso lokuqala le-AMO FOAkwi-AM i-thermoplastic yezakhiwo zeblade ye-injini yomoya, iiprojekthi ezimbini eziphantsi ziya kuphonononga ubuchule bokwenza i-injini yomoya ephucukileyo. IYunivesithi yaseColorado State (iFort Collins) ikhokela iprojekthi ekwasebenzisa ushicilelo lwe-3D ukwenza imidibaniso eyomelezwe yifayibha kwinoveli yangaphakathi yolwakhiwo lweblade yomoya,Owens Corning(eToledo, eOhio, eUnited States), NREL,Inkampani yeArkema(UKumkani wasePrussa, Pa., US), kunye neVestas Blades America (Brighton, Colo., US) njengamahlakani. Iprojekthi yesibini, ekhokelwa yi-GE Research (Niskayuna, NY, US), ibizwa ngokuba yi-AMERICA: I-Additive and Modular-Enabled Rotor Blades kunye ne-Integrated Composites Assembly. Ukusebenzisana noPhando lweGE ziILabhoratri yeSizwe ye-Oak Ridge(ORNL, Oak Ridge, Tenn., US), i-NREL, i-LM Wind Power (i-Kolding, eDenmark) kunye ne-GE Amandla aVuselelwayo (eParis, eFransi).
