Ntev reliant ntawm thermoset cov roj carbon-fiber ntau cov ntaub ntawv rau cov khoom siv carbon-fiber ntau ntawm cov pa roj carbon monoxide ntawm cov pa roj carbon monoxide ntawm cov pa roj carbon monoxide hnyav dua.
Thaum sov cov roj carbon-fiber ntau cov ntaub ntawv "tau nyob ib puag ncig, vp engantic cov chaw, vp engineation cov chaw, vp engineering nyob rau hauv collins Aerospace cov qauv Aerpace.
Thermoplastic carbon-fiber composites muaj feem cuam tshuam ntawm thermoset composites ntawm cov nqi siab thiab tus nqi qis, nws hais.
Nyob rau tsib xyoos dhau los, OEMS tau pib saib dhau qhov los ntawm cov khoom siv Resin-fiber ntau hauv tuam txhab, ua ntej siv cov khoom lag luam Resin (RTM) cov tswv yim los ua cov dav hlau, thiab tom qab ntawd Yuav ntiav cov tshuab thermoplastic sib xyaw.
GNK AERPARACACE tau nqis peev ntau hauv kev tsim nws cov cuab yeej Resin thiab RTM ntawm cov dav hlau loj tau them thiab ntawm cov nqi siab. GNK tam sim no ua rau 17-meter-ntev, ib leeg-thooj muaj duab tis spar siv Resin Instrumental Program 3 Kev Tshaj Tawm Tshaj Plaws Kev Ua Haujlwm.
OEMS 'Cov kev nqis peev hnyav-tsim kev nqis peev nyob rau hauv ob peb xyoos dhau los muaj kev siv lub zog ntawm thermoplastic seem, raws li Dion.
Qhov tseem ceeb tshaj plaws ntawm cov thermoset thiab thermoplastic cov ntaub ntawv nyob hauv qhov chaw, thiab ib zaug ua pa thermoset yuav tsum tau kho rau ntau teev nyob hauv ib lub autoclave. Cov txheej txheem yuav tsum muaj lub zog zoo thiab lub sijhawm, thiab yog li cov nqi ntau lawm ntawm cov thermoset feem ntau yuav nyob siab.
Kho cov ulters cov qauv molecular ntawm lub thermoset composite irrosite irreversibibely, muab qhov muab ib feem nws muaj zog. Txawm li cas los xij, ntawm txoj kev txhim kho thev naus laus zis tam sim no, kho kuj tseem ua rau cov khoom siv tsis zoo rau kev rov siv dua hauv thawj cov qauv txheej txheem.
Txawm li cas los xij, thermoplastic cov ntaub ntawv tsis tas yuav khoom txias lossis ci thaum ua rau hauv ntu, raws li kev puas tsuaj. Lawv tuaj yeem ntaus cim rau hauv cov duab kawg nkaus ntawm ib qho yooj yim-txhua qhov bracket rau cov Airbus A350 yog ib theem ntsuas cua sib xyaw ntawm cov khoom sib xyaw hauv nruab nrab.
Thermopoplastic cov ntaub ntawv tuaj yeem welded ua ke nyob rau ntau txoj kev, tso cai rau cov kev ua kom zoo nkauj uas tau ua los ntawm cov txheej txheem sau yooj yim. Niaj hnub no Infuction Vuam yog siv, uas tsuas yog tso cai rau tiaj tus, qhov chaw ua kom tuab li yuav tau ua los ntawm cov ntu ntu, raws li Dion. Txawm li cas los xij, Collins tab tom txhim kho kev co thiab kev sib txhuam cov txheej txheem rau kev tuaj yeem cia siab rau nws kom tsim cov qauv "tiag tiag nyuaj ntawm cov txheej txheem," nws hais.
Lub peev xwm rau Weld ua ke thermoplastic ntaub ntawv ua kom cov khoom siv nyuaj, yog li tsim cov txiaj ntsig zoo ntawm 10 feem pua, kev kwv yees xim av.
Tseem, thermoplastic muaj daim ntawv cog lus zoo dua rau cov hlau dua li ua thermoset sib xyaw, raws li xim av. Thaum muaj kev lag luam R & D tsomened ntawm kev tsim cov ntawv thov thermoplastic tseem "ntawm kev ua haujlwm ntawm lub cav hluav taws xob npaj txhij txhua tus,"
Ib qho kev thov yuav ua tau, piv txwv li, ua ib qho kev siv dav hlau uas xav tau rau cov neeg caij tsheb nrog cov neeg nrog caij tsheb uas muaj rau cov neeg nrog caij tsheb , hluav taws xob tswj lub rooj recline, qhov rai ntxoov ntxoo opacity, thiab lwm yam haujlwm.
Tsis zoo li thermoset cov ntaub ntawv, uas xav tau kho kom tsim lub ntsws, lub zog, thiab cov qauv molecular uas lawv tau txais los ntawm cov khoom siv thermoplastic ntawm cov khoom siv, raws li Dion.
Raws li qhov tshwm sim, cov ntaub ntawv thermoplastic muaj ntau dua kev cuam tshuam rau cov cuam tshuam ntau dua li thermoset cov ntaub ntawv thaum muab cov khoom muaj zog zoo sib xws thiab lub zog. "Yog li koj tuaj yeem tsim [qhov chaw] rau ntau thoj nplaum, tsuas yog txo qis qhov hnyav tsis xav tau cov hlau screws lossis cov ntsaws ruaj ruaj Cov.
Hloov cov thermoplastic ntau qhov chaw yuav tsum ua pov thawj cov txheej txheem yooj yim dua li xa thermoset seem. Ntawm lub xeev thev naus laus zis tam sim no (thiab rau qee lub sijhawm los ntawm cov qauv molecoset tiv thaiv kev siv cov khoom siv uas ua tau los ua cov khoom tshiab ntawm cov khoom tshiab ntawm cov khoom muaj zog tshiab.
Rov ua cov thermoset seem cuam tshuam cov pa roj carbon fibers nyob rau hauv cov khoom siv rau hauv ntev thiab hlawv lub fiber-and resin sib tov ua ntej reprocessing nws. Cov ntaub ntawv tau rau kev rov ua dua yog cov khoom siv hluav taws xob muaj zog dua li cov khoom siv hluav taws xob uas tau rov ua dua tshiab rau ib qho, "
Ntawm qhov tod tes, vim hais tias cov qauv molecular ntawm thermoplastic seem tsis hloov rau hauv cov txheej txheem ua kua thiab reprocessed mus rau hauv qhov chaw uas yog muaj zog li lub ces kaum.
Cov dav hlau tsim dav hlau tuaj yeem xaiv los ntawm kev xaiv ntau ntawm cov khoom siv thermopoplastic muaj los xaiv ntawm kev tsim qauv thiab kev tsim qauv. "Muaj ntau txoj kev loj heev ntawm cov resins" muaj nyob rau hauv uas ib-seem carbon fiber ntau fashes lossis ob-seem carbon filaments lossis ob-sab nraud yuav tau ua, ua rau muaj cov khoom siv sib txawv, tau hais txog kev sib txawv. "Cov resins zoo tshaj plaws yog cov resins tsawg heev," uas yaj ntawm cov kub tsis tshua muaj kub thiab yog li tuaj yeem tsim thiab tsim ntawm qis dua kub.
Cov chav kawm sib txawv ntawm thermoplays tseem muab cov nyom sib txawv (siab, nruab nrab, thiab qis) thiab tag nrho zoo, raws li dion. Cov khoom siv zoo tshaj plaws uas muaj txiaj ntsig zoo tshaj plaws, thiab muaj peev xwm sawv cev rau Achilles pob taws rau kev sib piv nrog cov ntaub ntawv thermoset. Feem ntau, lawv raug nqi ntau dua li Thermosets, thiab cov dav hlau cov dav hlau yuav tsum xav txog qhov tseeb hauv lawv cov nqi / txiaj ntsig tsim kev suav, hais tias xim av.
Ib nrab rau qhov laj thawj ntawd, GNK AERSOSPACE thiab lwm tus yuav ua txuas ntxiv rau cov ntaub ntawv uas tsim hluav taws xob thaum tsim cov qauv loj thaum tsim cov khoom loj rau cov dav hlau. Lawv twb siv cov ntaub ntawv thermoplastic cov khoom siv hauv kev ua cov txheej txheem me me xws li empennages, rudders, thiab cov lwj. Tsis ntev no, txawm li cas los xij, thaum cov neeg muaj ntim tau zoo, cov chaw tsim khoom lag luam yuav siv lawv ntau yam tshwj xeeb hauv kev ua lag luam EVTOL UA LAG LUAM, xaus lus Diion.
