izindaba

Emkhakheni wezindiza, ukusebenza kwezinto kuhlobene ngokuqondile nokusebenza, ukuphepha kanye namandla okuthuthukiswa kwezindiza. Ngokuthuthuka okusheshayo kobuchwepheshe bezindiza, izidingo zezinto zokwakha ziya ngokuya ziba nzima, hhayi nje kuphela ngamandla aphezulu kanye nokuminyana okuphansi, kodwa futhi nasekumelaneni nokushisa okuphezulu, ukumelana nokugqwala kwamakhemikhali, ukufakwa kukagesi kanye nezakhiwo ze-dielectric nezinye izici zokusebenza okuhle kakhulu.I-quartz fiberizinhlanganisela ze-silicone ziye zavela ngenxa yalokho, futhi ngokuhlanganiswa kwazo okuyingqayizivele kwezakhiwo, ziye zaba amandla amasha emkhakheni wezokundiza, ezifaka ubungqabavu obusha ekuthuthukisweni kwezimoto zesimanje zezindiza.

I-Fiber Pretreatment Ithuthukisa Ukubopha
Ukwelashwa kwangaphambili kwemicu ye-quartz kuyisinyathelo esibalulekile ngaphambi kokuhlanganisa imicu ye-quartz ne-silicone resin. Njengoba ubuso bezintambo ze-quartz buvame ukubushelelezi, okungahambisani nokubopha okuqinile ne-silicone resin, ubuso bezintambo ze-quartz bungashintshwa ngokwelashwa kwamakhemikhali, ukwelashwa kwe-plasma nezinye izindlela.
Ukwakhiwa Kwe-resin Okunembile Ukuhlangabezana Nezidingo
Ama-silicone resins adinga ukwakhiwa ngokunembile ukuze ahlangabezane nezimfuneko ezihlukene zokusebenza kwezinto eziyinhlanganisela yezimo ezihlukene zohlelo lokusebenza endaweni ye-aerospace. Lokhu kuhilela ukuklama ngokucophelela nokulungiswa kwesakhiwo samangqamuzana e-silicone resin, kanye nokwengezwa kwamanani afanele ama-ejenti okwelapha, ama-catalysts, ama-fillers nezinye izithasiselo.
Izinqubo Zokubumba Eziningi Zokuqinisekisa Ikhwalithi
Izinqubo ezijwayelekile zokubumba zezinhlanganisela ze-quartz fiber silicone zifaka i-Resin Transfer Molding (RTM), i-Vacuum Assisted Resin Injection (VARI), kanye ne-Hot Press Molding, ngayinye enezinzuzo zayo ezihlukile kanye nobubanzi bokusebenza.
I-Resin Transfer Molding (RTM) iyinqubo lapho ukwelashwa kwangaphambilinii-quartz fiberI-preform ifakwe esikhunjini, bese i-resin elungiselelwe ye-silicone ijojowe esikhunjeni ngaphansi kwemvelo ye-vacuum ukuze ingene ngokugcwele ku-fiber nge-resin, bese ekugcineni ilashwa futhi ibunjwe ngaphansi kwezinga lokushisa elithile nokucindezela.
Inqubo yomjovo we-vacuum-assisted resin, ngakolunye uhlangothi, isebenzisa ukumuncwa kwe-vacuum ukudonsa inhlaka ekubunjweni okumbozwe ngemicu ye-quartz ukuze kubonakale inhlanganisela yemicu nenhlaka.
Inqubo yokubumba yokucindezelwa okushisayo iwukuxuba imicu ye-quartz ne-silicone resin ngesilinganiso esithile, ifakwe esibunjeni, bese wenza inhlaka yelaphe ngaphansi kwezinga lokushisa eliphezulu nokucindezela, ukuze kwakheke into eyinhlanganisela.
Ngemuva kokwelashwa ukuze kupheleliswe izakhiwo zezinto ezibonakalayo
Ngemva kokubunjwa kwezinto ezihlanganisiwe, uchungechunge lwezinqubo zokwelashwa emva kokwelashwa, njengokwelashwa kokushisa nomshini womshini, kuyadingeka ukuze kuthuthukiswe izinto ezibonakalayo futhi kuhlangabezane nezidingo eziqinile zenkundla yezindiza. Ukwelashwa kokushisa kungaqeda ingcindezi esele ngaphakathi kwezinto eziyinhlanganisela, kuthuthukise ukuhlangana kobuso phakathi kwefayibha ne-matrix, futhi kuthuthukise ukuzinza nokuqina kwempahla. Ngokulawula ngokunembile imingcele yokwelashwa kokushisa njengezinga lokushisa, isikhathi kanye nezinga lokupholisa, ukusebenza kwezinto eziyinhlanganisela kungenziwa kahle.
Inzuzo Yokusebenza:

Amandla Akhethekile Aphakeme kanye Nokwehliswa Kwesisindo Esiqondile Se-Modulus
Uma kuqhathaniswa nezinto zensimbi zendabuko, izinhlanganisela ze-quartz fibre silicone zinezinzuzo ezibalulekile zamandla athile aphezulu (isilinganiso samandla nokuminyana) kanye nemodulus ethize ephezulu (isilinganiso semodulus ukuminyana). Emkhathini, isisindo semoto singenye yezinto ezibalulekile ezithinta ukusebenza kwayo. Ukwehliswa kwesisindo kusho ukuthi ukusetshenziswa kwamandla kungancishiswa, isivinini sendiza senyuswe, ububanzi kanye nomthwalo okhokhelwayo kunyuswe. Ukusetshenziswa kwei-quartz fiberizinhlanganisela ze-silicone resin ukwenza i-fuselage yendiza, amaphiko, umsila nezinye izingxenye zesakhiwo zinganciphisa kakhulu isisindo sendiza ngaphansi kwesisekelo sokuqinisekisa amandla esakhiwo nokuqina.

Izakhiwo ezinhle ze-dielectric zokuqinisekisa ukuxhumana nokuhamba
Kubuchwepheshe besimanje bezindiza, ukwethembeka kwezinhlelo zokuxhumana kanye nokuhamba kubalulekile. Ngezakhiwo zayo ezinhle ze-dielectric, i-quartz fiber silicone composite material isibe yinto ekahle yokukhiqiza i-radome yendiza, i-antenna yokuxhumana nezinye izinto. Ama-radome adinga ukuvikela i-radar antenna endaweni engaphandle futhi ngesikhathi esifanayo aqinisekise ukuthi amagagasi kagesi angangena ngokushelela nangokunembile amasignali. Izici eziphansi ze-dielectric ezihlala njalo neziphansi ze-tangent zokulahlekelwa kwezinhlanganisela ze-quartz fibre silicone zinganciphisa ngempumelelo ukulahlekelwa nokuhlanekezela kwamagagasi kagesi kunqubo yokudlulisa, iqinisekise ukuthi isistimu ye-radar ithola ngokunembile okuhlosiwe futhi iqondise indiza yendiza.
Ukumelana ne-ablation ezindaweni eziyingozi kakhulu
Kwezinye izingxenye zendiza ezikhethekile, njengegumbi elivuthayo kanye nombhobho wenjini yendiza, njll., zidinga ukumelana nezinga lokushisa eliphezulu kakhulu kanye nokushaywa kwegesi. Izinhlanganisela ze-quartz fiber silicone zibonisa ukumelana nokukhipha umoya okuhle kakhulu ezindaweni ezishisa kakhulu. Lapho ingaphezulu lezinto ezibonakalayo lingaphansi komthelela wokushisa okushisa okuphezulu, i-silicone resin izobola futhi i-carbonize, yakhe ungqimba lwe-carbonized layer enomphumela wokushisa ukushisa, kuyilapho imicu ye-quartz ikwazi ukugcina ubuqotho besakhiwo futhi iqhubeke nokunikeza ukusekelwa kwamandla kwento.

Izindawo zokufaka isicelo:
I-Fuselage kanye ne-Wing Structural Innovation
Izinhlanganisela ze-quartz fiber siliconezishintsha izinsimbi zendabuko lapho kwakhiwa ama-fuselages namaphiko endiza, okuholela ekwakhiweni okusha okubalulekile. Amafreyimu e-Fuselage namagida amaphiko enziwe ngalezi zinhlanganisela anikezela ngokuncishiswa kwesisindo esikhulu ngenkathi egcina amandla esakhiwo nokuqina.
Ukulungiswa kwengxenye ye-Aero-injini
I-Aero-injini iyingxenye eyinhloko yendiza, futhi ukuthuthukiswa kokusebenza kwayo kubalulekile ekusebenzeni okuphelele kwendiza. Izinhlanganisela ze-quartz fibre silicone zisetshenziswe ezingxenyeni eziningi ze-aero-injini ukuze kuzuzwe ukulungiselelwa nokuthuthukiswa kokusebenza kwezingxenye. Ezingxenyeni ezishisayo zenjini, njengegumbi elivuthayo nama-turbine blades, ukumelana nokushisa okuphezulu kwento eyinhlanganisela nokuhuzuka kungathuthukisa impilo yesevisi nokuthembeka kwezingxenye, futhi kunciphise izindleko zokunakekela injini.
