ʻO ka paʻi 3D o nā lau thermoplastic e hiki ai i ka wili wela a hoʻomaikaʻi i ka recyclability, e hāʻawi ana i ka hiki ke hōʻemi i ke kaumaha o ka turbine blade a me ke kumu kūʻai ma ka liʻiliʻi he 10%, a me ka manawa pōʻai hana e 15%.

ʻO kahi hui o nā mea noiʻi o National Renewable Energy Laboratory (NREL, Golden, Colo., US), i alakaʻi ʻia e NREL senior wind technology engineer Derek Berry, e hoʻomau nei i ka holomua i kā lākou ʻenehana hou no ka hana ʻana i nā ʻāpana makani turbine kiʻekiʻe e.hoʻonui i kā lākou hui ʻanao nā thermoplastics hiki ke hana hou ʻia a me ka hana hoʻohui (AM). Loaʻa ka holomua ma muli o ke kālā mai ka US Department of Energy's Advanced Manufacturing Office - nā makana i hoʻolālā ʻia e hoʻoulu i ka ʻenehana hou, hoʻomaikaʻi i ka huahana ikehu o ka hana ʻana o US a hiki i ka hana ʻana i nā huahana ʻokiʻoki.

I kēia mau lā, ʻo ka hapa nui o nā ʻāpana uila uila he like ka hoʻolālā clamshell. Eia naʻe, i mea e maʻalahi ai nā ʻūhā huila makani, lōʻihi, emi ke kumu kūʻai a ʻoi aku ka maikaʻi i ka hopu ʻana i ka ikehu makani - nā hoʻomaikaʻi koʻikoʻi i ka pahuhopu o ka ʻoki ʻana i nā hoʻokuʻu kinoea ʻōmaʻomaʻo ma kahi hapa ma o ka hoʻonui ʻana i ka ikehu makani - pono nā mea noiʻi e noʻonoʻo hou i ka clamshell maʻamau, he mea ia. ka manaʻo nui o ka hui NREL.

No ka hoʻomaka ʻana, ke kālele nei ka hui NREL i ka mea resin matrix. Ke hilinaʻi nei nā hoʻolālā o kēia manawa i nā ʻōnaehana resin thermoset e like me nā epoxies, polyesters a me nā vinyl esters, polymers i hoʻōla ʻia i ka wā i hoʻōla ʻia, hoʻopili ʻia e like me nā brambles.

"I ka manawa e hana ai ʻoe i kahi lau me kahi ʻōnaehana resin thermoset, ʻaʻole hiki iā ʻoe ke hoʻohuli i ke kaʻina hana," wahi a Berry. "ʻO ia ka mea e hana ai i ka makapaʻakikī e hana hou.”

Ke hana nei me kaInstitute for Advanced Composite Manufacturing Innovation(IACMI, Knoxville, Tenn., US) ma NREL's Composites Manufacturing Education and Technology (CoMET) Facility, ua hoʻomohala ka hui multi-institution i nā ʻōnaehana e hoʻohana ana i nā thermoplastics, ʻaʻole like me nā mea thermoset, hiki ke hoʻomehana ʻia e hoʻokaʻawale i nā polymers kumu, hiki i ka hopena. -o-ola (EOL) hana hou.

Hiki ke hoʻohui pū ʻia nā ʻāpana ʻāpana Thermoplastic me ka hoʻohana ʻana i ke kaʻina hana kuʻi wela e hiki ke hoʻopau i ka pono o nā mea hoʻopili - pinepine i nā mea kaumaha a pipiʻi - e hoʻomaikaʻi hou ana i ka ʻili.

"Me nā ʻāpana ʻelua thermoplastic, hiki iā ʻoe ke hoʻohui iā lākou a, ma o ka hoʻohana ʻana i ka wela a me ke kaomi, e hui pū me lākou," wahi a Berry. "ʻAʻole hiki iā ʻoe ke hana i kēlā me nā mea thermoset."

Ke neʻe nei i mua, NREL, me nā hoa hanaTPI Composite(Scottsdale, Ariz., US), Additive Engineering Solutions (Akron, Ohio, US),Mea Hana Mīkini Ingersoll(Rockford, Ill., US), Ke Kulanui ʻo Vanderbilt (Knoxville) a me IACMI, e hoʻomohala i nā ʻano hana koʻikoʻi o ka lau i mea e hiki ai i ke kumu kūʻai o ka hana kiʻekiʻe, lōʻihi loa - ʻoi aku ma mua o 100 mika ka lōʻihi - he haʻahaʻa haʻahaʻa. kaumaha.

Ma ka hoʻohana ʻana i ka paʻi 3D, ʻōlelo ka hui noiʻi hiki iā ia ke hana i nā ʻano hoʻolālā e pono ai no ka hoʻoponopono hou ʻana i nā ʻili turbine me nā ʻupena i hoʻolālā ʻia, ʻano ʻupena o nā ʻano like ʻole a me nā geometries ma waena o nā ʻili kino o ka ʻili turbine. E hoʻokomo ʻia nā ʻili maka me ka ʻōnaehana resin thermoplastic.

Inā kūleʻa lākou, e hoʻemi ka hui i ke kaumaha a me ke kumu kūʻai ma 10% (a ʻoi aku paha) a me ka manawa pōʻai hana ma ka liʻiliʻi he 15%.

Ma waho aʻe o kamakana nui AMO FOAno ka AM thermoplastic wind turbine blade structures, ʻelua mau papahana subgrant e ʻimi pū i nā ʻenehana hana ʻenehana ʻenehana. Ke alakaʻi nei ʻo Colorado State University (Fort Collins) i kahi papahana e hoʻohana pū ana i ka paʻi 3D no ka hana ʻana i nā mea hoʻohui i hoʻoikaika ʻia i ka fiber no nā hale makani makani kūloko hou, meOwens Corning(Toledo, Ohio, US), NREL,Arkema Inc.(King of Prussa, Pa., US), a me Vestas Blades America (Brighton, Colo., US) i mau hoa. ʻO ka lua o ka papahana, alakaʻi ʻia e GE Research (Niskayuna, NY, US), ua kapa ʻia ʻo AMERICA: Additive and Modular-Enabled Rotor Blades and Integrated Composites Assembly. ʻO ka hui pū ʻana me GE ResearchʻOka Ridge National Laboratory(ORNL, Oak Ridge, Tenn., US), NREL, LM Wind Power (Kolding, Denmark) a me GE Renewable Energy (Paris, Palani).
