Isikhathi Esisha Kuma-Carbon Fiber Composites - Umholi uSynesqo kanye ne-Aerospace Giant Bell Bamemezela Ubambiswano Oluhlelekile

4 Novemba 2024– USyensqo, umholi womhlaba wonke ezintweni ezithuthukisiwe, kanye neBell Textron Inc., inkampani engaphansi kweTextron Inc., bangene ekubambisaneni okuhloswe ngakho ukusheshisa ukuthuthukiswa kwezimboni zokukhiqiza okuhlanganisiwe kwezicelo zezindiza zesizukulwane esilandelayo. Ubambiswano luzosebenzisa ubuchwepheshe obusha beSyensqo bokubeka iDirect Dry Fiber (DDF) kanye ne-CYCOM® EP2750 ephulukisa ngokushesha.uhlelo lokulungiselelaukuthuthukisa ukusebenza kahle kokukhiqiza nokunciphisa izindleko zezakhiwo zezindiza eziyinkimbinkimbi.

1.Ukuthuthukiswa Kobuchwepheshe:Kusukela emahoreni kuya emaminithini ngesikhathi sokwelapha

Izinqubo zokwelapha zendabuko ezisekelwe ku-autoclave zebanga lezindizai-carbon fiberIzinhlanganisela zidla isikhathi futhi zidinga amandla amaningi, zinciphisa ukwamukelwa okukhulu. Uhlelo lwe-Syensqo lwe-CYCOM® EP2750 epoxy prepreg lubhekana nale nselele ngokufeza ukuqina okugcwele ngemizuzu embalwa—okungaphezu kuka-70% ngokushesha kunezinto ezivamile—ngenkathi ludinga i-oven kuphela kune-autoclave. Izinto zigcina izakhiwo zemishini ze-T800-grade, okwenza zifanele izakhiwo eziyinhloko njengalezo ezisetshenziswa endizeni ye-Bell's V-280 Valor tiltrotor. Ukuhambisana kwayo namajiyometri agobile futhi ayinkimbinkimbi kuqinisekisa ukufakwa kwefayibha efanayo kanye nokufakwa kwe-resin, okuvumela ukukhiqizwa okukhulu kwezingxenye ezinkulu ngaphandle kokuphazamisa ukusebenza.

2.Inqubo Ehlanganisiwe:I-DDF + Ukukhulelwa Okusheshayo Okuphulukisa Ngaphambi Kokukhulelwa

Ubuchwepheshe be-DDF bukaSyensqo buvumela ukubekwa okunembile kwefayibha eyomile ngokuqondisa okulawulwayo kanye nokuqukethwe kwe-resin, okuhlanganiswa kalula nohlelo lwe-CYCOM® EP2750. Lokhu kuhlangana "okumanzi okomile" kuvumela ukulungiswa kwesikhathi sangempela ngesikhathi sokulala, ukwenza ngcono ukusebenza kwamaphiko, ama-fuselage, nezinye izimo eziyinkimbinkimbi. UBell uhlela ukusebenzisa le ndlela ehlanganisiwe ezingxenyeni ezifana nama-rotor cowlings nama-nacelles endiza enophephela emhlane iBell 429, ehlose ukunciphisa isikhathi somjikelezo wokukhiqiza ngo-40% kanye nokuncipha kwesibalo semishini kanye nokuthembela kwabasebenzi.

3.Umongo Wemboni:Ukushintsha kusuka ekusungulweni kwezinto ezibonakalayo kuya ekusebenzeni kahle kokukhiqiza

Ukubambisana kweSyensqo-Bell kubonisa ukuthambekela okubanzi embonini lapho abahlinzeki bezinto ezibonakalayo kanye nama-OEM bethuthukisa khona izixazululo zokukhiqiza eziklanyelwe bona. Ngenkathi abanye abadlali—njengeCovestro neGKN Aerospace (ama-UV-curing composites) kanye ne-Arkema ne-Airbus (ama-thermoplastics)—begxila ezindleleni ezihlukile, isu likaSyensqo ligcizelela inqubo ekwazi ukwandiswa, esebenza kuphela kuhhavini ehambisana nezinketho zokuphakelwa kwezindiza ezikhona ngaphandle kokudinga ukutshalwa kwezimali okukhulu.

4. Imiphumela yeAbakhiqizi Bezinhlanganisela ZaseShayina

Nakuba iShayina ifinyelele impumelelo ku-T700/T800 ukukhiqizwa kwe-carbon fiber, ukuthembela ezintweni ezithunyelwe kwamanye amazwe kanye nemininingwane yenqubo yangaphandle kusalokhu kuyisithiyo. Imodeli yeSyensqo-Bell inikeza ukuqonda okubalulekile:

∙Qinisa ukuthuthukiswa ngokubambisana kwenqubo yezinto ezibonakalayo ukuze wakhe amakhono ahlanganisiwe;

∙Beka phambili amasu ashibhile, asheshayo njengokufaka ukucindezela okusheshayo noma ukufaka i-resin ukuze kukhiqizwe ngobuningi izakhiwo zesibili;

∙Sebenzisana nabakhiqizi be-eVTOL kanye ne-UAV ukuze kuhlolwe amaketanga okukhiqiza asheshayo futhi kuqhutshwe ukusetshenziswa kobuchwepheshe obuphindaphindayo.

Isiphetho

Ubambiswano phakathi kukaSyensqo noBell lubonisa ushintsho olubalulekile kusukela ekwenzeni ngokwezifiso kwelebhu kuya ekukhiqizweni okulungiselelwa ifektri okukwazi ukulinganiswa ezinhlanganisela zezindiza. Ukuze iShayina incintisane emhlabeni jikelele, ukuvala igebe kubuchwepheshe bokukhiqiza—hhayi izinto zokwakha kuphela—kuzoba yinto ebalulekile eminyakeni eyishumi ezayo.
