izindaba

Emkhakheni wezindiza, ukusebenza kwezinto kuhlobene ngqo nokusebenza, ukuphepha kanye nekhono lokuthuthukiswa kwezindiza. Ngokuthuthuka okusheshayo kobuchwepheshe bezindiza, izidingo zezinto ziya ngokuya ziba nzima, hhayi nje kuphela ngamandla aphezulu kanye nobuningi obuphansi, kodwa futhi nasekumelaneni nokushisa okuphezulu, ukumelana nokugqwala kwamakhemikhali, ukufudumala kukagesi kanye nezakhiwo ze-dielectric kanye nezinye izici zokusebenza okuhle kakhulu.I-fibre ye-quartzNgenxa yalokho, kuye kwavela izinhlanganisela ze-silicone, futhi ngenhlanganisela yazo eyingqayizivele yezakhiwo, ziye zaba amandla amasha emkhakheni wezindiza, zifaka amandla amasha ekuthuthukisweni kwezimoto zezindiza zesimanje.

Ukwelashwa Kwangaphambi Kwefayibha Kuthuthukisa Ukubopha
Ukwelashwa kwangaphambi kwemicu ye-quartz kuyisinyathelo esibalulekile ngaphambi kokuhlanganisa imicu ye-quartz nge-silicone resin. Njengoba ubuso bemicu ye-quartz buvame ukuba bushelelezi, okungavumeli ukubopha okuqinile ne-silicone resin, ubuso bemicu ye-quartz bungashintshwa ngokwelashwa ngamakhemikhali, ukwelashwa nge-plasma nezinye izindlela.
Ukwakhiwa Kwe-Resin Okunembile Ukuze Kuhlangatshezwane Nezidingo
Ama-resin e-silicone adinga ukwakheka ngokunembile ukuze ahlangabezane nezidingo zokusebenza kwezinto ezihlanganisiwe ezahlukahlukene zezimo ezahlukene zokusetshenziswa emkhakheni wezindiza. Lokhu kuhilela ukuklama ngokucophelela nokulungiswa kwesakhiwo sama-molecule e-resin ye-silicone, kanye nokwengezwa kwamanani afanele ama-curing agents, ama-catalyst, ama-fillers nezinye izithasiselo.
Izinqubo Zokubumba Eziningi Ukuqinisekisa Ikhwalithi
Izinqubo zokubumba ezivamile ze-quartz fiber silicone composites zifaka phakathi i-Resin Transfer Molding (RTM), i-Vacuum Assisted Resin Injection (VARI), kanye ne-Hot Press Molding, ngayinye enezinzuzo zayo ezihlukile kanye nobubanzi bokusetshenziswa.
I-Resin Transfer Molding (RTM) inqubo lapho i-Resin Transfer Molding (RTM) iphathwa khona.i-fibre ye-quartzI-preform ifakwa ku-mold, bese kuthi i-silicone resin elungisiwe ifakwe ku-mold ngaphansi kwendawo ye-vacuum ukuze ingene ngokuphelele ku-fiber ne-resin, bese ekugcineni iphola futhi ibunjwe ngaphansi kwezinga lokushisa elithile kanye nengcindezi.
Ngakolunye uhlangothi, inqubo yokujova i-resin esizwa yi-vacuum, isebenzisa i-vacuum suction ukudonsa i-resin ezikhumbeni ezimbozwe ngemicu ye-quartz ukuze kutholakale inhlanganisela yemicu ne-resin.
Inqubo yokubumba ngokucindezela okushisayo iwukuxuba imicu ye-quartz kanye ne-silicone resin ngesilinganiso esithile, ifakwe esikhumbeni, bese yenza i-resin iqine ngaphansi kokushisa okuphezulu kanye nengcindezi, ukuze kwakheke izinto ezihlanganisiwe.
Ngemva kokwelashwa ukuze kuthuthukiswe izakhiwo zezinto ezibonakalayo
Ngemva kokuba izinto ezihlanganisiwe sezibunjiwe, uchungechunge lwezinqubo zangemva kokwelashwa, njengokwelashwa kokushisa kanye nomshini, luyadingeka ukuze kuthuthukiswe izakhiwo zezinto futhi kuhlangatshezwane nezidingo eziqinile zensimu yezindiza. Ukwelashwa kokushisa kungasusa ukucindezeleka okusele ngaphakathi kwezinto ezihlanganisiwe, kuthuthukise ukubopha phakathi kwefayibha kanye ne-matrix, futhi kuthuthukise ukuzinza nokuqina kwezinto. Ngokulawula ngokunembile imingcele yokwelashwa kokushisa njengokushisa, isikhathi kanye nesivinini sokupholisa, ukusebenza kwezinto ezihlanganisiwe kungathuthukiswa.
Inzuzo Yokusebenza:

Amandla Akhethekile Aphezulu kanye Nokunciphisa Isisindo Se-Modulus Ekhethekile
Uma kuqhathaniswa nezinto zensimbi zendabuko, izinhlanganisela ze-silicone ze-quartz fiber zinezinzuzo ezibalulekile zamandla aphezulu athile (isilinganiso samandla kuya kobuningi) kanye ne-modulus ephezulu ethile (isilinganiso se-modulus kuya kobuningi). Endizeni, isisindo semoto singenye yezinto ezibalulekile ezithinta ukusebenza kwayo. Ukunciphisa isisindo kusho ukuthi ukusetshenziswa kwamandla kungancishiswa, isivinini sokundiza sande, ububanzi kanye nomthwalo okhokhelwayo kwande. Ukusetshenziswa kwei-fibre ye-quartzIzinhlanganisela ze-silicone resin zokukhiqiza i-fuselage yendiza, amaphiko, umsila kanye nezinye izingxenye zesakhiwo zinganciphisa kakhulu isisindo sendiza ngaphansi kwesisekelo sokuqinisekisa amandla nokuqina kwesakhiwo.

Izakhiwo ezinhle ze-dielectric ukuqinisekisa ukuxhumana nokuzulazula
Ebuchwephesheni bezindiza banamuhla, ukuthembeka kwezinhlelo zokuxhumana kanye nokuzulazula kubalulekile. Ngezakhiwo zayo ezinhle ze-dielectric, izinto ezihlanganisiwe ze-quartz fiber silicone sezibe yinto efanelekile yokukhiqiza i-radome yendiza, i-antenna yokuxhumana nezinye izingxenye. Ama-Radomes adinga ukuvikela i-antenna ye-radar endaweni yangaphandle futhi ngesikhathi esifanayo aqinisekise ukuthi amagagasi kagesi angangena kahle futhi adlulise amasignali ngokunembile. Izici zokulahlekelwa yi-dielectric ezihlala njalo neziphansi ze-quartz fiber silicone composites zinganciphisa ngempumelelo ukulahleka nokuphambuka kwamagagasi kagesi enkambisweni yokudlulisa, kuqinisekiswe ukuthi uhlelo lwe-radar luthola ngokunembile ithagethi futhi luqondise ukundiza kwendiza.
Ukumelana nokukhishwa kwendle ezindaweni ezibucayi
Kwezinye izingxenye ezikhethekile zendiza, njengegumbi lokusha kanye nomlomo wenjini yendiza, njll., zidinga ukumelana nokushisa okuphezulu kakhulu kanye nokushaqeka kwegesi. Izinhlanganisela ze-silicone ze-quartz fiber zibonisa ukumelana okuhle kakhulu kwe-ablation ezindaweni zokushisa okuphezulu. Lapho ubuso bezinto buthinteka ilangabi lokushisa eliphezulu, i-silicone resin izobola futhi ibe yi-carbon, yakhe ungqimba lwezingqimba ze-carbonized ezinomphumela wokuvimbela ukushisa, kuyilapho imicu ye-quartz ikwazi ukugcina ubuqotho besakhiwo futhi iqhubeke nokunikeza ukwesekwa kwamandla kwezinto.

Izindawo Zokusebenza:
Ukusungula Izinto Ezintsha Zesakhiwo Se-Fuselage Ne-Wing
Izinhlanganisela ze-silicone ze-quartz fiberzithatha indawo yezinsimbi zendabuko ekwakhiweni kwama-fuselage namaphiko ezindiza, okuholela ekusungulweni okusha okuphawulekayo kwesakhiwo. Amafreyimu e-fuselage nama-wing girders enziwe ngalezi zinhlanganisela anikeza ukunciphisa okukhulu kwesisindo ngenkathi egcina amandla nokuqina kwesakhiwo.
Ukuthuthukiswa kwezingxenye ze-Aero-injini
Injini ye-Aero iyisici esiyinhloko sendiza, futhi ukuthuthukiswa kokusebenza kwayo kubalulekile ekusebenzeni kwayo konke kwendiza. Izinhlanganisela ze-silicone ze-quartz fiber zisetshenziswe ezingxenyeni eziningi zenjini ye-aero ukuze kufezwe ukulungiswa kanye nokuthuthukiswa kokusebenza kwezingxenye. Ezingxenyeni ezishisayo zenjini, njengegumbi lokushiswa kanye nama-blade e-turbine, ukumelana nokushisa okuphezulu kanye nokuguguleka kwezinto ezihlanganisiwe kungathuthukisa ngempumelelo impilo yesevisi kanye nokuthembeka kwezingxenye, futhi kunciphise izindleko zokugcinwa kwenjini.
