Ukuphrinta kwe-3D yezindwani ze-thermoplastic kunika amandla ukushisela okushisayo futhi kuthuthukisa ukugaywa kabusha, kunikeza amandla okunciphisa isisindo se-turbine blade kanye nezindleko okungenani ngo-10%, kanye nesikhathi somjikelezo wokukhiqiza ngo-15%.
Ithimba labacwaningi beNational Renewable Energy Laboratory (NREL, Golden, Colo., US), eliholwa unjiniyela omkhulu wezobuchwepheshe bomoya be-NREL uDerek Berry, bayaqhubeka nokuthuthukisa amasu abo anoveli okwenza izindwani zezinjini zomoya ezithuthukisiweukuthuthukisa inhlanganisela yaboyokukhiqiza kabusha kwe-thermoplastics kanye ne-additive Production (AM).Intuthuko yenziwe yaba nokwenzeka ngoxhaso lweHhovisi Lokukhiqiza Okuthuthukile loMnyango Wezamandla wase-US - imiklomelo eklanyelwe ukugqugquzela ukuqanjwa kabusha kwezobuchwepheshe, ukuthuthukisa ukukhiqizwa kwamandla okukhiqizwa kwe-US kanye nokwenza kube lula ukukhiqizwa kwemikhiqizo esezingeni eliphezulu.
Namuhla, izindwani eziningi ze-wind turbine esikalini zinomklamo ofanayo we-clamshell: Izikhumba ezimbili ze-fiberglass blade zihlanganiswa ne-adhesive futhi zisebenzisa ingxenye eyodwa noma eminingana yokuqinisa eyinhlanganisela ebizwa ngokuthi ama-shear webs, inqubo elungiselelwe ukusebenza kahle eminyakeni engama-25 edlule.Kodwa-ke, ukwenza ama-wind turbine blades abe lula, abe made, angabizi futhi asebenze kahle ekubambeni amandla omoya - ukuthuthukiswa okubalulekile emgomweni wokunciphisa ukukhishwa kwegesi ebamba ukushisa ngokwengxenye ngokwandisa ukukhiqizwa kwamandla omoya - abacwaningi kumele bacabange kabusha ngokuphelele i-clamshell evamile, into ukugxila okuyinhloko kwethimba le-NREL.
Ukuqala, ithimba le-NREL ligxile ezintweni ze-resin matrix.Imiklamo yamanje incike ezinhlelweni ze-thermoset resin ezifana nama-epoxies, ama-polyester nama-vinyl esters, ama-polymers okuthi, uma seselaphekile, axhumane njengama-brambles.
"Uma usukhiqize i-blade nge-thermoset resin system, awukwazi ukuhlehlisa inqubo," kusho uBerry.“Lokho nakho kwenza i-bladeokunzima ukugaywa kabusha.”
Ukusebenza neI-Institute for Advanced Composites Manufacturing Innovation(IACMI, Knoxville, Tenn., US) ku-NREL's Composites Manufacturing Education and Technology (CoMET) Facility, ithimba lezikhungo eziningi lenze amasistimu asebenzisa i-thermoplastics, okuthi, ngokungafani nezinto ze-thermoset, ezingashiswa ukuze zihlukanise ama-polymers asekuqaleni, anikeze amandla ukuphela. -of-life (EOL) recyclability.
Izingxenye ze-Thermoplastic blade nazo zingahlanganiswa kusetshenziswa inqubo yokushisela eshisayo engaqeda isidingo sezinto zokunamathisela - ngokuvamile izinto ezisindayo nezimba eqolo - okuthuthukisa ukuphinda kusetshenziswe i-blade.
"Ngezingxenye ezimbili ze-thermoplastic blade, unamandla okuzihlanganisa futhi, ngokusebenzisa ukushisa nokucindezela, zijoyine," kusho uBerry."Awukwazi ukwenza lokho ngezinto ze-thermoset."
Ukuqhubekela phambili, i-NREL, kanye nabalingani bephrojekthiI-TPI Composites(Scottsdale, Ariz., US), Additive Engineering Solutions (Akron, Ohio, US),Ingersoll Machine Tools(I-Rockford, Ill., US), i-Vanderbilt University (Knoxville) kanye ne-IACMI, izothuthukisa izakhiwo ze-blade core ukuze zinikeze amandla ukukhiqizwa okungabizi kakhulu kwama-blades asebenza kahle kakhulu, amade kakhulu - ngaphezu kwamamitha angu-100 ubude - aphansi kakhulu. isisindo.
Ngokusebenzisa ukuphrinta kwe-3D, ithimba labacwaningi lithi lingakhiqiza izinhlobo zemiklamo edingekayo ukuze kuthuthukiswe ama-turbine blade ngama-cores akhiwe kahle, amise okwenetha anokuminyana okuhlukahlukene namajiyometri phakathi kwezikhumba zesakhiwo se-turbine blade.Izikhumba ze-blade zizofakwa kusetshenziswa i-thermoplastic resin system.
Uma bephumelela, ithimba lizonciphisa isisindo se-turbine blade futhi libize ngo-10% (noma ngaphezulu) kanye nesikhathi somjikelezo wokukhiqiza okungenani ngo-15%.
Ngaphezu kwe-umklomelo omkhulu we-AMO FOAngezinhlaka ze-AM thermoplastic wind turbine blade, amaphrojekthi amabili angaphansi azophinde ahlole amasu athuthukile okukhiqiza i-wind turbine.I-Colorado State University (Fort Collins) ihola iphrojekthi esebenzisa ukuphrinta kwe-3D ukwenza izinhlanganisela eziqiniswe yifayibha yezakhiwo ezinoveli zangaphakathi zomoya,Owens Corning(eToledo, e-Ohio, e-US), NREL,Inkampani engu-Arkema Inc.(Inkosi yasePrussa, Pa., US), kanye neVestas Blades America (Brighton, Colo., US) njengabalingani.Iphrojekthi yesibili, eholwa yi-GE Research (Niskayuna, NY, US), ibizwa nge-AMERICA: I-Additive and Modular-Enabled Rotor Blades kanye ne-Integrated Composites Assembly.Ukusebenzisana ne-GE Research kukhonaI-Oak Ridge National Laboratory(ORNL, Oak Ridge, Tenn., US), NREL, LM Wind Power (Kolding, Denmark) kanye ne-GE Renewable Energy (Paris, France).
