"Manje senza izinhlelo zangaphakathi futhi sisebenzisana namakhasimende ukuthola izingxenye zalobu buchwepheshe obusha," kusho uCorvaglia."Lezi zingxenye kungase kudingeke ziklanywe kabusha futhi zifaneleke ngaphambi kokuthi kuqale ukukhiqizwa."Kungani?“Inhloso wukwenza indiza ibe lula ngangokunokwenzeka, kodwa ngentengo encintisanayo.Ngakho-ke, kufanele futhi nokwandisa ukushuba.Nokho, singathola ukuthi ingxenye eyodwa inganciphisa isisindo, noma ihlonze izingxenye eziningi ezinemimo efanayo, engonga izindleko zemali eningi.”
Uphinde wagcizelela ukuthi kuze kube manje, lobu buchwepheshe busezandleni zabantu abambalwa.“Kodwa sithuthukise obunye ubuchwepheshe bokuzenza lezi zinqubo ngokuzenzakalelayo ngokwengeza ukubumba kwezindaba okuthuthuke kakhulu.Sifaka i-laminate eyisicaba bese sikhipha ingxenye yayo, isilungele ukusetshenziswa.Sisezinhlelweni zokuklama kabusha izingxenye futhi sithuthukise izingxenye eziyisicaba noma ezinephrofayili.Isigaba se-CCM.”
"Manje sesinolayini wokukhiqiza we-CCM oguquguqukayo kakhulu ku-CETMA," kusho uPappadà.“Lapha singasebenzisa izingcindezi ezehlukene njengoba kudingeka ukuze sifinyelele izimo eziyinkimbinkimbi.Ulayini womkhiqizo esizowuthuthukisa kanye no-Leonardo uzogxila kakhulu ekuhlangabezaneni nezingxenye zawo ezithile ezidingekayo.Sikholelwa ukuthi imigqa ehlukene ye-CCM ingasetshenziselwa izintambo eziyisicaba nezimise okwe-L esikhundleni somumo oyinkimbinkimbi.Ngale ndlela, uma kuqhathaniswa nemishini emikhulu yokunyathelisa esetshenziswa njengamanje ukukhiqiza izingxenye ze-TPC zejometri eziyinkimbinkimbi, singenza izindleko zemishini Igcine iphansi.”
I-CETMA isebenzisa i-CCM ukuze ikhiqize ama-stringers namaphaneli asuka ku-carbon fiber/PEKK one-way way tape, bese isebenzisa ukushiselwa kwalesi sibonisi senqwaba ye-keel ukuze iwaxhume kuphrojekthi ye-Clean Sky 2 KEELBEMAN ephethwe yi-EURECAT.Umthombo|“Umbukiso wokushisela imishayo ye-thermoplastic keel uyabonakala.”
"I-induction welding iyathakazelisa kakhulu ngezinto ezihlanganisiwe, ngoba izinga lokushisa lingalungiswa futhi lilawulwe kahle kakhulu, ukushisa kuyashesha kakhulu futhi ukulawula kunembile kakhulu," kusho uPappadà.“Ngokubambisana noLeonardo, sakha i-induction welding ukuze sijoyine izingxenye ze-TPC.Kodwa manje sesicabanga ukusebenzisa i-induction welding for in-situ consolidation (ISC) ye-TPC tape.Kuze kube manje, senze i-carbon fibre tape entsha, Ingashiswa ngokushesha ngokushisela induction usebenzisa umshini okhethekile.Itheyiphu isebenzisa izinto eziyisisekelo ezifanayo njengetheyiphu yezohwebo, kodwa inokwakheka okuhlukile ukuze kuthuthukiswe ukushisisa kwe-electromagnetic.Ngenkathi sithuthukisa izakhiwo zemishini, siphinde sicubungula inqubo yokuzama ukuhlangabezana nezidingo Ezihlukene, njengokuthi singabhekana kanjani nazo ngendlela engabizi kakhulu nangempumelelo nge-automation.”
Uveze ukuthi kunzima ukufeza i-ISC nge-TPC tape ngokukhiqiza okuhle.“Ukuze uyisebenzisele ukukhiqizwa kwezimboni, kufanele ufudumale futhi uphole ngokushesha futhi ufake ingcindezi ngendlela elawuleke kakhulu.Ngakho-ke, sinqume ukusebenzisa i-induction welding ukushisa indawo encane kuphela lapho izinto zihlanganiswa khona, kanti amanye amaLaminate agcinwa ebanda.UPappadà uthi i-TRL ye-induction welding esetshenziselwa ukuhlanganisa iphezulu.“
Ukuhlanganiswa kwesayithi kusetshenziswa ukushisisa kokungeniswa kubonakala kuphazamisa kakhulu-okwamanje, akekho omunye umphakeli we-OEM noma wesigaba owenza lokhu esidlangalaleni."Yebo, lokhu kungase kube ubuchwepheshe obuphazamisayo," kusho uCorvaglia.“Sifake izicelo zobunikazi bomshini nezinto zokwakha.Umgomo wethu umkhiqizo ofana nezinto eziyinhlanganisela ye-thermoset.Abantu abaningi bazama ukusebenzisa i-TPC ye-AFP (i-Automatic Fiber Placement), kodwa isinyathelo sesibili kufanele sihlanganiswe.Ngokwejiyomethri, Lona umkhawulo omkhulu ngokwezindleko, isikhathi somjikelezo kanye nosayizi wengxenye.Eqinisweni, singase sishintshe indlela esikhiqiza ngayo izingxenye ze-aerospace.”
Ngaphezu kwe-thermoplastics, uLeonardo uyaqhubeka nokucwaninga ubuchwepheshe be-RTM.“Lena ngenye indawo lapho sibambisene khona ne-CETMA, futhi intuthuko entsha esekelwe kubuchwepheshe obudala (SQRTM kulokhu) inelungelo lobunikazi.Ukubumba okufanelekile kokudluliswa kwe-resin kwaqalwa yi-Radius Engineering (Salt Lake City, Utah, USA) (SQRTM).UCorvaglia uthe: “Kubalulekile ukuthi sibe nendlela ye-autoclave (OOA) esivumela ukuthi sisebenzise izinto esezivele zifanelekile.“Lokhu futhi kusivumela ukuthi sisebenzise ama-prepregs anezici nezimfanelo ezaziwayo.Sisebenzise lobu buchwepheshe ukuze sidizayine, sibonise futhi sifake isicelo selungelo lobunikazi lamafreyimu ewindi lendiza.“
Naphezu kwe-COVID-19, i-CETMA isacubungula uhlelo lukaLeonardo, lapha kuboniswa ukusetshenziswa kwe-SQRTM ukwenza izakhiwo zamawindi endiza ukuze kuzuzwe izingxenye ezingenasici futhi kusheshiswe ukwakheka kwangaphambili uma kuqhathaniswa nobuchwepheshe bendabuko be-RTM.Ngakho-ke, uLeonardo angashintsha izingxenye zensimbi eziyinkimbinkimbi ngezingxenye ezihlanganisiwe ze-mesh ngaphandle kokucubungula okwengeziwe.Umthombo |CETMA, Leonardo.
UPappadà waveza: “Lobu futhi ubuchwepheshe obudala, kodwa uma ungena ku-inthanethi, awukwazi ukuthola ulwazi ngalobu buchwepheshe.”Nakulokhu, sisebenzisa amamodeli okuhlaziya ukuze sibikezele futhi silungiselele amapharamitha enqubo.Ngalobu buchwepheshe, singathola ukusabalalisa okuhle kwe-resin-azikho izindawo ezomile noma ukuqoqwa kwe-resin-futhi cishe i-zero porosity.Ngenxa yokuthi singakwazi ukulawula okuqukethwe kwefayibha, singakwazi ukukhiqiza izakhiwo eziphakeme kakhulu, futhi ubuchwepheshe bungasetshenziswa ukukhiqiza izimo eziyinkimbinkimbi.Sisebenzisa izinto ezifanayo ezihlangabezana nezidingo zokwelashwa kwe-autoclave, kodwa sebenzisa indlela ye-OOA, kodwa futhi unganquma ukusebenzisa inhlaka epholisa ngokushesha ukuze unciphise isikhathi somjikelezo sibe imizuzu embalwa.“
"Ngisho nange-prepreg yamanje, sehlise isikhathi sokwelapha," kusho uCorvaglia.“Isibonelo, uma kuqhathaniswa nomjikelezo ojwayelekile we-autoclave wamahora angu-8-10, ezingxenyeni ezifana namafreyimu ewindi, i-SQRTM ingasetshenziswa amahora angu-3-4.Ukushisa nokucindezela kusetshenziswa ngokuqondile ezingxenyeni, futhi isisindo sokushisa sincane.Ngaphezu kwalokho, ukushiswa kwe-resin ewuketshezi ku-autoclave kuyashesha kunomoya, futhi ikhwalithi yezingxenye nayo ihle kakhulu, ezuzisa kakhulu izimo eziyinkimbinkimbi.Akukho kuphinda kusetshenzwe, cishe ku-zero voids kanye nekhwalithi ephezulu kakhulu, ngoba ithuluzi likuLawula, hhayi isikhwama se-vacuum.
ULeonardo usebenzisa ubuchwepheshe obuhlukahlukene ukuze asungule izinto ezintsha.Ngenxa yokuthuthuka okusheshayo kobuchwepheshe, ikholelwa ukuthi ukutshalwa kwezimali ku-R&D (i-TRL ephansi) enobungozi obukhulu kubalulekile ekuthuthukisweni kobuchwepheshe obusha obudingekayo emikhiqizweni yesikhathi esizayo, obudlula amandla okuthuthukisa (isikhathi esifushane) imikhiqizo ekhona kakade enayo. .Uhlelo lukaLeonardo lwe-R&D luka-2030 luhlanganisa inhlanganisela enjalo yamasu esikhathi esifushane nawesikhathi eside, okuwumbono obumbene wenkampani esimeme nencintisanayo.
Njengengxenye yalolu hlelo, izokwethula i-Leonardo Labs, inethiwekhi yelabhorethri yenkampani yamazwe ngamazwe ye-R&D enikezelwe ku-R&D nokusungula izinto ezintsha.Ngo-2020, inkampani izofuna ukuvula amalabhorethri ayisithupha okuqala kaLeonardo eMilan, Turin, Genoa, Rome, Naples naseTaranto, futhi iqasha abacwaningi abangama-68 (abakwaLeonardo Research Fellows) abanamakhono emikhakheni elandelayo): Izinhlelo ezingama-36 ezihlakaniphile ezizimele ze izikhundla zobuhlakani bokwenziwa, ukuhlaziywa kwedatha okukhulu okungu-15, ikhompyutha esebenza kahle kakhulu engu-6, ukufakwa kukagesi kwenkundla yezindiza ezi-4, izinto ezisetshenziswayo nezakhiwo ezi-5, kanye nobuchwepheshe be-quantum obungu-2.I-Leonardo Laboratory izodlala indima yokuqamba okusha kanye nomqambi wobuchwepheshe besikhathi esizayo bukaLeonardo.
Kuyaphawuleka ukuthi ubuchwepheshe bukaLeonardo obuthengiswa ezindizeni bungase busetshenziswe eminyangweni yabo yezwe nezasolwandle.Hlala ubukele ukuze uthole izibuyekezo ezengeziwe ngo-Leonardo nomthelela wawo ongaba khona ezintweni eziyinhlanganisela.
I-matrix ibopha i-fiber-reinforced material, inikeze ingxenye eyinhlanganisela ukuma kwayo, futhi inquma ikhwalithi yayo engaphezulu.I-matrix eyinhlanganisela ingaba i-polymer, i-ceramic, insimbi noma i-carbon.Lona umhlahlandlela wokukhetha.
Kuzinhlelo zokusebenza eziyinhlanganisela, lezi zakhiwo ezincane ezingenalutho zithatha indawo yevolumu eningi ngesisindo esincane, futhi zikhuphule umthamo wokucubungula kanye nekhwalithi yomkhiqizo.
