Kusindikiza kwa 3D kwa masamba a thermoplastic kumathandizira kuwotcherera kwamafuta ndikuwongolera kubwezeretsedwanso, kupereka kuthekera kochepetsa kulemera kwa tsamba la turbine ndi mtengo wake ndi 10%, ndi nthawi yozungulira ndi 15%.

Gulu la ofufuza a National Renewable Energy Laboratory (NREL, Golden, Colo., US), motsogozedwa ndi injiniya wamkulu waukadaulo wamphepo wa NREL Derek Berry, akupitiliza kupititsa patsogolo njira zawo zatsopano zopangira masamba apamwamba a turbine yamphepo.kuonjezera mkangano wawoya recyclable thermoplastics and additive production (AM). Kupititsa patsogoloku kudatheka chifukwa cha ndalama zochokera ku Advanced Manufacturing Office ya dipatimenti ya Mphamvu ku US - mphotho zomwe zidapangidwa kuti zilimbikitse luso laukadaulo, kupititsa patsogolo mphamvu zopanga mphamvu ku US ndikupangitsa kuti apange zinthu zotsogola.

Masiku ano, masamba ambiri opangira magetsi opangidwa ndi mphepo ali ndi mapangidwe ofanana ndi a clamshell: Zikopa ziwiri za magalasi a fiberglass amalumikizidwa pamodzi ndi zomatira ndipo amagwiritsa ntchito chinthu chimodzi kapena zingapo zowumitsa zotchedwa shear webs, njira yomwe idakongoletsedwa kuti igwire bwino ntchito zaka 25 zapitazi. Komabe, kuti ma turbine amphepo akhale opepuka, atali, otsika mtengo komanso othandiza kwambiri pogwira mphamvu yamphepo - kusintha kofunikira kuti cholinga chochepetsera mpweya wowonjezera kutentha pagawo pakuwonjezera kupanga mphamvu yamphepo - ochita kafukufuku ayenera kuganizanso mozama za clamshell wamba, chinthu chomwe ndi Cholinga chachikulu cha timu ya NREL.

Kuyamba, gulu la NREL likuyang'ana kwambiri zinthu za resin matrix. Mapangidwe apano amadalira makina a thermoset resin monga ma epoxies, ma polyesters ndi vinyl esters, ma polima omwe, akachiritsidwa, amalumikizana ngati minganga.

"Mukangopanga tsamba lokhala ndi thermoset resin system, simungathe kuyisintha," akutero Berry. "Izi zimapanganso tsambazovuta kubwezeretsanso.”

Kugwira ntchito ndiInstitute for Advanced Composites Manufacturing Innovation(IACMI, Knoxville, Tenn., US) mu NREL's Composites Manufacturing Education and Technology (CoMET) Facility, gulu lamagulu ambiri linapanga machitidwe omwe amagwiritsa ntchito thermoplastics, omwe, mosiyana ndi zipangizo za thermoset, akhoza kutenthedwa kuti alekanitse ma polima oyambirira, kupangitsa mapeto. -of-life (EOL) recyclability.

Ziwalo za tsamba la thermoplastic zitha kuphatikizidwanso pogwiritsa ntchito kuwotcherera komwe kungathe kuthetsa kufunikira kwa zomatira - zomwe nthawi zambiri zimakhala zolemera komanso zodula - kupititsa patsogolo kukonzanso kwa tsamba.

"Ndi zigawo ziwiri za thermoplastic blade, mumatha kuzibweretsa pamodzi ndipo, pogwiritsa ntchito kutentha ndi kupanikizika, mugwirizane nazo," akutero Berry. "Simungathe kuchita izi ndi zida za thermoset."

Kupita patsogolo, NREL, pamodzi ndi ogwira nawo ntchitoTPI Composites(Scottsdale, Ariz., US), Additive Engineering Solutions (Akron, Ohio, US),Zida Za Makina a Ingersoll(Rockford, Ill., US), Vanderbilt University (Knoxville) ndi IACMI, adzapanga mapangidwe apamwamba a blade kuti athe kupanga zotsika mtengo kwambiri, masamba aatali kwambiri - opitirira mamita 100 m'litali - omwe ndi otsika kwambiri. kulemera.

Pogwiritsa ntchito kusindikiza kwa 3D, gulu lofufuza likuti litha kupanga mitundu yofunikira kuti ma turbine apangidwe amakono okhala ndi makina opangidwa bwino kwambiri, opangidwa ndi ukonde wosiyanasiyana komanso ma geometri pakati pa zikopa zamapangidwe a turbine blade. Zikopa za tsamba zidzalowetsedwa pogwiritsa ntchito thermoplastic resin system.

Ngati apambana, gululo lichepetsa kulemera kwa tsamba la turbine ndikudula ndi 10% (kapena kupitilira apo) ndi nthawi yozungulira ndi 15%.

Kuwonjezera pamphoto yayikulu ya AMO FOAkwa AM thermoplastic wind turbine blade blade, mapulojekiti awiri ocheperako adzafufuzanso njira zapamwamba zopangira makina opangira mphepo. Colorado State University (Fort Collins) ikutsogolera pulojekiti yomwe imagwiritsanso ntchito kusindikiza kwa 3D kupanga zophatikizira zolimbitsa ulusi wazinthu zatsopano zamkati zamkati, ndiOwens Corning(Toledo, Ohio, US), NREL,Malingaliro a kampani Arkema Inc.(King of Prussa, Pa., US), ndi Vestas Blades America (Brighton, Colo., US) monga ogwirizana. Ntchito yachiwiri, motsogozedwa ndi GE Research (Niskayuna, NY, US), imatchedwa AMERICA: Additive and Modular-Enabled Rotor Blades and Integrated Composites Assembly. Kuyanjana ndi GE Research ndiOak Ridge National Laboratory(ORNL, Oak Ridge, Tenn., US), NREL, LM Wind Power (Kolding, Denmark) ndi GE Renewable Energy (Paris, France).
