3D luam ntawv ntawm cov hniav nyiaj hniav kub ua kom cov thermal vuam thiab txhim kho cov khoom siv rov ua dua tshiab, muab lub peev xwm los txo cov turbine hniav hnyav thiab tus nqi tsawg kawg yog 10%, thiab lub sijhawm ntau lawm los ntawm 15%.

Ib pab pawg ntawm National Renewable Energy Laboratory (NREL, Golden, Colo., US) cov kws tshawb fawb, coj los ntawm NREL tus kws tshaj lij cua tshuab cua tshuab Derek Berry, tab tom txuas ntxiv mus ua lawv cov txheej txheem tshiab los tsim cov cua tshuab cua tshuab los ntawmtxuas ntxiv lawv cov kev sib xyawntawm cov khoom siv thermoplastics thiab cov khoom siv ntxiv (AM).Qhov kev nce qib tau ua tau los ntawm kev pab nyiaj los ntawm US Department of Energy's Advanced Manufacturing Office - khoom plig tsim los txhawb kev tsim kho tshuab, txhim kho lub zog tsim khoom ntawm Asmeskas kev tsim khoom thiab pab tsim cov khoom lag luam txiav.

Niaj hnub no, feem ntau cov nqi hluav taws xob cua turbine blades muaj tib lub clamshell tsim: Ob lub fiberglass hniav tawv tawv yog sib koom ua ke nrog cov nplaum thiab siv ib los yog ob peb cov khoom sib xyaw ua ke hu ua shear webs, txheej txheem optimized rau efficiency tshaj 25 xyoo dhau los.Txawm li cas los xij, ua kom cua turbine hniav sib zog, ntev dua, tsis tshua kim thiab zoo dua ntawm kev ntes cua zog - kev txhim kho tseem ceeb rau lub hom phiaj ntawm kev txiav cov pa hluav taws xob hauv tsev cog khoom ib feem los ntawm kev ua kom muaj zog cua - cov kws tshawb fawb yuav tsum rov xav txog cov pa clamshell, ib yam dab tsi uas yog. pab pawg NREL lub hom phiaj tseem ceeb.

Txhawm rau pib, pab pawg NREL tab tom tsom mus rau cov khoom siv matrix resin.Cov qauv tsim tam sim no cia siab rau cov thermoset resin systems xws li epoxies, polyesters thiab vinyl esters, polymers uas, ib zaug kho, cross-links zoo li brambles.

Berry hais tias "Thaum koj tsim cov hniav nrog lub thermoset resin system, koj tsis tuaj yeem thim rov qab cov txheej txheem," Berry hais.“Qhov ntawd [tseem] ua rau cov hniavnyuaj rau rov siv dua”

Ua haujlwm nrog covLub koom haum rau Advanced Composites Manufacturing Innovation(IACMI, Knoxville, Tenn., US) nyob rau hauv NREL's Composites Manufacturing Education and Technology (CoMET) Facility, ntau lub koom haum pab pawg tsim cov tshuab uas siv cov thermoplastics, uas, tsis zoo li cov ntaub ntawv thermoset, tuaj yeem ua kom sov kom sib cais cov thawj polymers, ua kom kawg. -of-life (EOL) recyclability.

Thermoplastic hniav tuaj yeem tuaj yeem koom nrog siv cov txheej txheem vuam thermal uas tuaj yeem tshem tawm qhov xav tau ntawm cov nplaum - feem ntau hnyav thiab kim khoom - ntxiv dag zog rau cov hniav rov ua dua tshiab.

Berry hais tias "Nrog ob lub thermoplastic blade Cheebtsam, koj muaj peev xwm coj lawv ua ke thiab, los ntawm kev siv cov cua sov thiab siab, koom nrog lawv," Berry hais."Koj tsis tuaj yeem ua qhov ntawd nrog cov khoom siv thermoset."

Tsiv mus tom ntej, NREL, nrog rau cov neeg koom tes ua haujlwmTPI Composites(Scottsdale, Ariz., Asmeskas), Additive Engineering Solutions (Akron, Ohio, US),Ingersoll Tshuab cuab yeej(Rockford, Ill., Teb Chaws Asmeskas), Vanderbilt University (Knoxville) thiab IACMI, yuav tsim cov txheej txheem tshiab ntawm cov hniav tseem ceeb los pab kom tus nqi tsim nyog ntawm kev ua tau zoo, cov hniav ntev heev - zoo tshaj 100 meters ntev - uas kuj qis. hnyav.

Los ntawm kev siv 3D luam ntawv, pab pawg tshawb fawb tau hais tias nws tuaj yeem tsim cov qauv tsim uas xav tau los hloov kho cov turbine hniav nrog kev tsim kho zoo, cov qauv zoo li cov cores ntawm qhov sib txawv ntawm qhov sib txawv thiab cov geometries ntawm cov tawv nqaij ntawm cov hniav turbine.Cov tawv nqaij ntawm cov tawv nqaij yuav raug infused siv lub thermoplastic resin system.

Yog tias lawv ua tiav, pab pawg yuav txo qis turbine hniav hnyav thiab tus nqi los ntawm 10% (lossis ntau dua) thiab lub sijhawm tsim khoom los ntawm tsawg kawg 15%.

Ntxiv rau qhovPrime AMO FOA khoom pligrau AM thermoplastic cua turbine hniav cov qauv, ob txoj haujlwm subgrant tseem yuav tshawb nrhiav cov cua turbine siab heev.Colorado State University (Fort Collins) tab tom ua ib txoj haujlwm uas tseem siv 3D luam ntawv los ua cov fiber ntau ntxiv rau cov qauv tshiab sab hauv cua tshuab, nrog rauOwens Corning(Toledo, Ohio, Asmeskas), NREL,Arkema Inc.(King of Prussa, Pa., US), thiab Vestas Blades America (Brighton, Colo., US) ua koom tes.Qhov thib ob txoj haujlwm, coj los ntawm GE Kev Tshawb Fawb (Niskayuna, NY, US), yog hu ua AMERICA: Additive thiab Modular-Enabled Rotor Blades thiab Integrated Composites Assembly.Kev koom tes nrog GE Kev Tshawb Fawb yogOak Ridge National Laboratory(ORNL, Oak Ridge, Tenn., US), NREL, LM Cua Fais Fab (Kolding, Denmark) thiab GE Renewable Energy (Paris, Fabkis).
