Yakareba yakatsamira pane thermoset kabhoni-fiber zvinhu zvekugadzira yakasimba kwazvo inoumbwa zvikamu zvezvimiro zvendege, aerospace OEMs ave kugamuchira imwe kirasi yekabhoni-fiber zvinhu sekufambira mberi kwetekinoroji kuvimbisa kugadzira otomatiki kwezvikamu zvitsva zvisiri-thermoset pavhoriyamu yakakwira, mutengo wakaderera, uye. kureruka uremu.

Nepo thermoplastic kabhoni-fiber composite zvinhu "zvave zviripo kwenguva yakareba," nguva pfupi yadarika vagadziri vezvemuchadenga vanogona kufunga kushandiswa kwavo kwakapararira mukugadzira zvikamu zvendege, kusanganisira zvekutanga zvimiro, akadaro Stephane Dion, vp engineering kuCollins Aerospace's Advanced Structures unit.

Thermoplastic kabhoni-fiber macomposites anogona kupa aerospace OEMs akati wandei mabhenefiti pamusoro pe thermoset composites, asi kusvika nguva pfupi yadarika vagadziri vaisakwanisa kugadzira zvikamu kubva muthermoplastic composite pamitengo yakakwira uye nemutengo wakaderera, akadaro.

Mumakore mashanu apfuura, maOEM akatanga kutarisa kunze kwekugadzira zvikamu kubva kune thermoset zvinhu senyika yekabhoni-fiber inoumba chikamu chekugadzira sainzi yakagadziridzwa, kutanga kushandisa resin infusion uye resin transfer molding (RTM) maitiro ekugadzira zvikamu zvendege, uyezve. kushandisa thermoplastic composites.

GKN Aerospace yakaisa mari yakawanda mukugadzira resin-infusion yayo uye tekinoroji yeRTM yekugadzira zvinhu zvakakura zvendege zvinokwanisika uye nemitengo yakakwira. GKN ikozvino inogadzira 17-mita-yakareba, imwe-chidimbu-chimedu composite wing spar vachishandisa resin infusion kugadzira, maererano naMax Brown, vp yehunyanzvi hweGKN Aerospace's Horizon 3 advanced-technologies initiative.

OEMs 'inorema composite-kugadzira investimendi mumakore mashoma apfuura yaisanganisirawo kushandisa zvine hungwaru mukuvandudza kugona kubvumidza yakakwira-vhoriyamu kugadzirwa kwezvikamu zve thermoplastic, sekureva kwaDion.

Musiyano unonyanya kuzivikanwa pakati pe thermoset uye thermoplastic zvinhu zviri mukuti thermoset zvinhu zvinofanirwa kuchengetwa munzvimbo inotonhora zvisati zvaumbwa kuita zvikamu, uye kana zvaumbwa, chikamu che thermoset chinofanirwa kurapwa kwemaawa mazhinji mu autoclave. Maitiro acho anoda simba rakawanda uye nguva, uye saka mitengo yekugadzira yezvikamu zve thermoset inowanzoramba yakakwirisa.

Kurapa kunoshandura chimiro che molecular ye thermoset composite zvisingadzoreki, zvichipa chikamu chacho simba rayo. Nekudaro, padanho razvino rekuvandudza tekinoroji, kurapa kunoitawo kuti zvinhu zviri muchikamu dzisakodzere kushandiswazve muchikamu chekutanga chechimiro.

Nekudaro, zvinhu zve thermoplastic hazvidi kutonhora kwekuchengetera kana kubheka kana zvaitwa kuita zvikamu, maererano naDion. Zvinogona kudhindwa muchimiro chekupedzisira chechikamu chakareruka-chese bracket yemafuselage fuselage muAirbus A350 chikamu che thermoplastic composite-kana muchikamu chepakati chechikamu chakaoma kunzwisisa.

Zvishandiso zveThermoplastic zvinogona kubatanidzwa pamwechete nenzira dzakasiyana-siyana, zvichibvumira zvikamu zvakaoma, zvakanyanyisa kuumbwa kuti zviitwe kubva kune akareruka maumbirwo. Nhasi induction welding inonyanya kushandiswa, iyo inongobvumira flat, inogara-kukora zvikamu kuti zvigadzirwe kubva kudiki-zvikamu, maererano naDion. Nekudaro, Collins ari kugadzira vibration uye friction welding matekiniki ekujoinha thermoplastic zvikamu, izvo kana zvakambosimbiswa kuti zvinotarisira zvinozopedzisira zvazvibvumira kuburitsa "zvimiro zvemberi zvakaoma," akadaro.

Kugona kubatanidza zvinhu zve thermoplastic kugadzira zvimiro zvakaoma zvinobvumira vagadziri kuti vabvise simbi screws, fasteners, uye hinges zvinodiwa ne thermoset zvikamu zvekujoinha nekupeta, nekudaro vachigadzira bhenefiti yekudzikisa huremu inosvika gumi muzana, Brown anofungidzira.

Zvakadaro, thermoplastic composites inosunga zvirinani kune simbi pane kuita thermoset composites, maererano naBrown. Nepo maindasitiri R&D yakanangana nekugadzira mashandisirwo anoshanda eiyo thermoplastic chivakwa chinoramba chiri "padanho rekutanga-kukura tekinoroji yekugadzirira," inogona kupedzisira yarega mainjiniya emuchadenga kugadzira zvinhu zvine hybrid thermoplastic-uye-simbi yakabatanidzwa zvimiro.

Chishandiso chimwe chete chinogona, semuenzaniso, kuve chigaro chimwe chete, chakareruka chemutyairi wendege chine ese esimbi-based circuitry inodiwa kune interface inoshandiswa nemutyairi kusarudza nekudzora sarudzo dzake dzevaraidzo yekubhururuka, mwenje wechigaro, feni yepamusoro. , zvigaro zvinodzorwa nemagetsi, mumvuri wehwindo opacity, uye mamwe mabasa.

Kusiyana nemidziyo yethermoset, inoda kurapwa kuti ibudise kuoma, simba, uye chimiro chinodiwa kubva munzvimbo dzavanogadzirwa, mamorekuru ezvigadzirwa zve thermoplastic composite haachinje kana agadzirwa kuita zvikamu, maererano naDion.

Nekuda kweizvozvo, thermoplastic zvinhu zvinonyanya kutsemuka-kupokana pane simba pane thermoset zvinhu apo zvichipa zvakafanana, kana zvisina kusimba, kusimba kwesimba uye simba. "Saka unokwanisa kugadzira [zvikamu] kusvika kumageji akatetepa," akadaro Dion, zvichireva kuti thermoplastic zvikamu zvinorema zvishoma pane chero zvikamu zve thermoset zvavanotsiva, kunyangwe kunze kwekuderedza huremu kunokonzerwa nenyaya yekuti thermoplastic parts haidi masiruu esimbi kana mafasteners. .

Kudzokorodza zvikamu zve thermoplastic kunofanirawo kuratidza maitiro ari nyore pane kudzokorodza zvikamu zve thermoset. Panguva yazvino yetekinoroji (uye kwenguva ichauya), shanduko isingadzoreki muchimiro chemolecular inogadzirwa nekurapa thermoset zvinhu zvinodzivirira kushandiswa kwezvinhu zvakadzokororwa kugadzira zvikamu zvitsva zvesimba rakaenzana.

Kudzokorodza zvikamu zve thermoset kunosanganisira kukuya kabhoni fiber muzvinhu kuita hurefu hudiki uye kupisa musanganiswa wefiber-and-resin usati waigadzirisa zvakare. Zvinhu zvakawanikwa kuti zvigadziriswe zvakare hazvina kusimba pane iyo thermoset iyo yakagadziridzwa chikamu chakagadzirwa, saka kudzokorora zvikamu zve thermoset kuita zvitsva zvinowanzoshandura "chimwe chimiro kuita chepamusoro," akadaro Brown.

Nekune rimwe divi, nekuti mamorekuru ezvikamu zve thermoplastic haashanduke muzvikamu-kugadzira uye zvikamu-kujoinha maitiro, anogona kungonyungudutswa kuita yemvura uye kudzokororwa kuita zvikamu zvakasimba sepakutanga, maererano naDion.

Vagadziri vendege vanogona kusarudza kubva pakusarudzwa kwakasiyana kwezvinhu zvethermoplastic zvinowanikwa kusarudza kubva mukugadzira nekugadzira zvikamu. "Rwanda rwakanaka rwemaresini" anowanikwa mune imwe-dimensional kabhoni fiber filaments kana maviri-dimensional weave anogona kuisirwa, achigadzira akasiyana zvinhu, akadaro Dion. "Iyo inonyanya kunakidza resin ndeye yakaderera-yakanyunguduka resin," iyo inonyunguduka pane yakadzika tembiricha uye saka inogona kuumbwa nekuumbwa nekudzika kwakadzika.

Makirasi akasiyana e thermoplastics anopawo akasiyana kuomarara zvivakwa (yepamusoro, yepakati, uye yakaderera) uye huwandu hwemhando, sekureva kwaDion. Iyo yepamusoro-mhando resin inodhura zvakanyanya, uye kugona kunomiririra Achilles chitsitsinho che thermoplastics mukuenzanisa ne thermoset zvinhu. Kazhinji, vanodhura kupfuura thermosets, uye vagadziri vendege vanofanira kufunga nezvechokwadi ichocho mumutengo wavo / mabhenefiti ekugadzira maverengero, akadaro Brown.

Zvimwe nekuda kwechikonzero ichocho, GKN Aerospace nevamwe vacharamba vachitarisa zvakanyanya pane thermoset zvinhu pakugadzira zvikamu zvakakura zvezvimiro zvendege. Ivo vanotoshandisa thermoplastic zvinhu zvakanyanya mukugadzira zvidiki zvimiro senge empennages, rudders, uye spoilers. Nenguva isipi, zvakadaro, kana yakakwira-vhoriyamu, yakachipa-yepasi yekugadzira yeakareruka thermoplastic zvikamu zvave muitiro, vagadziri vanozozvishandisa zvakanyanya zvakanyanya-kunyanya mumusika uri kukura weVTOL UAM, akapedzisa Dion.
