Daabacaadda 3D ee xaashida thermoplastic waxay awood u siinaysaa alxanka kulaylka waxayna wanaajisaa dib-u-warshadaynta, iyada oo bixisa awoodda lagu dhimayo miisaanka marawaxadaha marawaxadaha iyo qiimaha ugu yaraan 10%, iyo wakhtiga wareegga wax soo saarka 15%.

Koox ka socota Shaybaadhka Tamarta La cusboonaysiin karo (NREL, Golden, Colo., US), oo uu hogaaminayo NREL injineerka sare ee tignoolajiyada dabaysha Derek Berry, ayaa sii wada inay horumariyaan farsamooyinkooda cusub si ay u soo saaraan marawaxadaha dabaysha horumarsansii wadida isku-darkoodaee heerkulbeegyada dib loo warshadayn karo iyo wax soo saarka wax lagu daro (AM). Horumarka waxaa lagu suurtageliyay maalgelin ka timid Waaxda Tamarta Mareykanka ee Xafiiska Waxsoosaarka Horukacsan - abaal-marinno loogu talagalay in lagu kiciyo hal-abuurnimada tignoolajiyada, hagaajinta wax-soo-saarka tamarta ee wax-soo-saarka Mareykanka iyo awood-siinta wax-soo-saarka wax-soo-saarka horumarsan.

Maanta, inta badan mashiinnada marawaxadaha dabaysha ee cabbirka tamarta leh waxay leeyihiin naqshad isku mid ah: Laba harag oo fiberglass ah ayaa ku xidhan koollo waxayna isticmaalaan hal ama dhawr qaybood oo adag oo isku dhafan oo loo yaqaan webs xiirid, habraaca loo habeeyay waxtarka 25kii sano ee la soo dhaafay. Si kastaba ha ahaatee, si loo sameeyo marawaxadaha marawaxadaha dabaysha kuwa fudud, dheer, kharash yar oo waxtar leh marka la qabanayo tamarta dabaysha - hagaajinta muhiimka ah ee hadafka goynta gaaska aqalka dhirta lagu koriyo qayb ahaan iyada oo la kordhinayo wax soo saarka tamarta dabaysha - cilmi-baarayaashu waa inay gebi ahaanba dib u eegaan clamshell caadiga ah, wax waa kooxda NREL diiradda koowaad.

Si loo bilaabo, kooxda NREL waxay diiradda saarayaan walxaha matrixka resin. Naqshadaynta hadda waxay ku tiirsan yihiin nidaamyada resin-ka heerkulbeegga sida epoxies, polyester-ka iyo vinyl esters, polymers kuwaas oo, mar la daweeyay, isku xidha isku xidhka sida brambles.

"Marka aad soo saarto daab leh nidaamka resin thermoset, ma beddeli kartid habka," Berry ayaa yidhi. "Taasi [sidoo kale] waxay samaysaa daabkaay adagtahay in dib loo warshadeeyo.”

La shaqayntaMachadka Hal-abuurka Wax-soo-saarka Sare ee Isku-dhafka Sare(IACMI, Knoxville, Tenn., US) ee NREL's Composites Manufacturing Education and Technology (CoMET) Xarunta, kooxda hay'adaha badan ayaa sameeyay habab adeegsada heerkulbeegyada, kaas oo, ka duwan qalabka kulaylka, lagu kululayn karo si loo kala saaro polymers-kii asalka ahaa, taas oo awood u siinaysa dhamaadka Dib-u-warshadaynta -of-nolosha (EOL).

Qaybaha daabka Thermoplastic sidoo kale waa lagu biirin karaa iyadoo la isticmaalayo habka alxanka kulaylka kaas oo meesha ka saari kara baahida xabagta - badiyaa walxo culus oo qaali ah - taas oo sii xoojinaysa dib u warshadaynta daabka.

"Laba qaybood oo heerkulbeeg ah oo heerkulbeeg ah, waxaad awood u leedahay inaad isu keento oo, iyada oo loo marayo codsiga kulaylka iyo cadaadiska, ku biir," Berry ayaa yidhi. "Taas kuma samayn kartid qalabka heerkulbeegga."

Hore u socoshada, NREL, oo ​​ay weheliso la-hawlgalayaasha mashruucaIsku-dhafka TPI(Scottsdale, Ariz., US), Xallinta Injineerinka Dheeraadka ah (Akron, Ohio, US),Qalabka mashiinka Ingersoll(Rockford, Ill., US), Jaamacadda Vanderbilt (Knoxville) iyo IACMI, waxay horumarin doonaan dhismooyin xudunta u ah daab cusub si ay awood ugu yeeshaan wax-soosaarka waxtarka leh ee waxtarka leh ee waxtarka leh, boogaha aadka u dhaadheer - oo dhererkoodu ka badan yahay 100 mitir - kuwaas oo aad u hooseeya miisaanka.

Isticmaalka daabacaadda 3D, kooxda cilmi-baadhistu waxay sheegtay inay soo saari karto noocyada naqshadaha loo baahan yahay si loo casriyeeyo marawaxadaha marawaxadaha leh oo aad loo farsameeyay, qaab dhismeed shabag leh oo cufnaanta kala duwan leh iyo joomatariyada u dhexeeya maqaarka qaab dhismeedka ee marawaxadaha marawaxadaha. Maqaarka daabku waxa lagu shubi doonaa iyada oo la isticmaalayo nidaamka resin thermoplastic.

Haddii ay ku guuleystaan, kooxdu waxay dhimi doontaa miisaanka marawaxadaha marawaxadaha iyo qiimaha 10% (ama ka badan) iyo waqtiga wareegga wax soo saarka ugu yaraan 15%.

Intaa waxaa dheerAMO FOA awarddhismayaasha marawaxadaha marawaxadaha dabaysha ee AM thermoplastic, laba mashruuc oo hoose ayaa sidoo kale sahamin doona farsamooyinka wax soo saarka marawaxadaha dabaysha ee horumarsan. Jaamacadda Colorado State University (Fort Collins) waxay hogaaminaysaa mashruuc sidoo kale adeegsada daabacaadda 3D si ay u sameeyaan isku-darka fiber-xoojiyey ee dhismayaasha cusub ee dabaysha gudaha, oo lehOwens Corning(Toledo, Ohio, US), NREL,Arkema Inc.(King of Prussa, Pa., US), iyo Vestas Blades America (Brighton, Colo., US) oo shuraako ah. Mashruuca labaad, oo ay hogaaminayso GE Research (Niskayuna, NY, US), waxa lagu naanaysaa AMERICA: Isku-darka iyo Hababka-Awooda Rotor Blades iyo Isku-dhafka Isku-dhafka ah. La shaqaynta GE Research waaShaybaadhka Qaranka ee Oak Ridge(ORNL, Oak Ridge, Tenn., US), NREL, LM Korantada Dabaysha (Kolding, Denmark) iyo GE Tamarta La cusboonaysiin karo (Paris, France).
