Kudhinda kwe3D kwe thermoplastic blades kunogonesa kupisa kwemoto uye kunatsiridza kudzokororwa, kuchipa mukana wekudzikisa huremu hweturbine blade uye mutengo neinosvika gumi muzana, uye nguva yekutenderera kwekugadzira ne15%.

Chikwata cheNational Renewable Energy Laboratory (NREL, Goridhe, Colo., US) vaongorori, vachitungamirwa neNREL mukuru weinjiniya wemhepo Derek Berry, vari kuenderera mberi nekusimudzira hunyanzvi hwavo hwekugadzira mashizha emhepo emhepo.kuwedzera musanganiswa wavoye recyclable thermoplastics uye additive kugadzira (AM). Kufambira mberi uku kwakaitwa nekugoneka nemari kubva kuUS Dhipatimendi reMagetsi's Advanced Manufacturing Office - mibairo yakagadzirirwa kukurudzira hunyanzvi hwetekinoroji, kuvandudza kugadzirwa kwesimba rekugadzira kweUS uye kugonesa kugadzirwa kwezvigadzirwa zvemhando yepamusoro.

Nhasi, mablade eturbine emhepo akawanda ane dhizaini yakafanana: Matehwe maviri efiberglass blade anosunganidzwa pamwe chete nekunamira uye anoshandisa chinhu chimwe kana akati wandei chinoomesa chinodaidzwa kuti shear webs, maitiro akagadziridzwa kushanda zvakanaka mumakore makumi maviri nemashanu apfuura. Zvisinei, kuita kuti mashizha emagetsi emhepo ave nyore, akareba, asingadhuri uye anonyanya kushanda pakubata simba remhepo - kuvandudzwa kwakakosha kune chinangwa chekucheka mhepo inopisa gasi muchikamu nekuwedzera kugadzirwa kwesimba remhepo - vatsvakurudzi vanofanira kufungisisa zvachose clamshell, chimwe chinhu chiri. iyo NREL inonyanya kutarisa.

Kutanga, timu yeNREL iri kutarisa pane resin matrix zvinhu. Madhizaini azvino anotsamira pane thermoset resin masisitimu senge epoxies, polyesters uye vinyl esters, mapolymers ayo, kana angopora, anoyambuka-link senge brambles.

"Kana ukangogadzira blade ine thermoset resin system, haugone kudzosera maitiro," anodaro Berry. "Izvowo [zvakare] zvinogadzira bladezvakaoma kugadzirisa zvakare.”

Kushanda neInstitute for Advanced Composites Manufacturing Innovation(IACMI, Knoxville, Tenn., US) muNREL's Composites Manufacturing Education and Technology (CoMET) Facility, iyo yakawanda-institution timu yakagadzira masisitimu anoshandisa thermoplastics, ayo, kusiyana ne thermoset zvinhu, anogona kupisa kuti aparadzanise mapolymer ekutanga, achigonesa kupera. -ye-hupenyu (EOL) kushandiswazve.

Thermoplastic blade zvikamu zvinogona zvakare kubatanidzwa uchishandisa yekupisa welding process iyo inogona kubvisa kudiwa kwezvinonamira - kazhinji zvinorema uye zvinodhura zvinhu - zvichiwedzera kuwedzera blade kudzokororwa.

"Nezvikamu zviviri zve thermoplastic blade, unokwanisa kuzviunza pamwe chete uye, kuburikidza nekushandiswa kwekupisa nekumanikidza, zvibatanidze," anodaro Berry. "Iwe haugone kuzviita nezvinhu zve thermoset."

Kufambira mberi, NREL, pamwe chete nevabatsiri veprojekitiTPI Composites(Scottsdale, Ariz., US), Additive Engineering Solutions (Akron, Ohio, US),Ingersoll Machine Zvishandiso(Rockford, Ill., US), Vanderbilt University (Knoxville) uye IACMI, ichagadzira hunyanzvi hwekugadzira blade core zvivakwa kuti zvigone kugadzirwa-zvinodhura kugadzirwa kwepamusoro-kushanda, mashizha akareba kwazvo - anopfuura 100 metres pakureba - ayo akadzikira. uremu.

Nekushandisa 3D kudhinda, timu yekutsvagisa inoti inogona kugadzira mhando dzemagadzirirwo anodiwa kugadzirisa turbine mablades ane akagadzirwa zvakanyanya, mambure-akaita masikirwo macores eakasiyana densities uye geometries pakati pematehwe echimiro cheturbine blade. Matehwe eblade achaiswa uchishandisa thermoplastic resin system.

Kana vakabudirira, timu ichadzikisa huremu hweturbine blade uye mutengo ne10% (kana kupfuura) uye nguva yekutenderera kwekugadzira neinosvika 15%.

Mukuwedzera kuneprime AMO FOA mubairoye AM thermoplastic mhepo turbine blade zvimiro, maviri subgrant mapurojekiti anozoongorora epamusoro mhepo turbine kugadzira matekiniki. Colorado State University (Fort Collins) iri kutungamirira chirongwa chinoshandisawo 3D kudhinda kugadzira faibha-yakasimbiswa makombisi ezvivakwa zvemukati zvemhepo, zvineOwens Corning(Toledo, Ohio, US), NREL,Nhoroondo ye Arkema Inc.(Mambo wePrussa, Pa., US), uye Vestas Blades America (Brighton, Colo., US) sevabatsiri. Yechipiri purojekiti, inotungamirwa neGE Research (Niskayuna, NY, US), inonzi AMERICA: Additive uye Modular-Enabled Rotor Blades uye Integrated Composites Assembly.
