iindaba

Kwicandelo leenqwelo-moya, ukusebenza kwezixhobo kunxulumene ngokuthe ngqo nokusebenza, ukhuseleko kunye nokukwazi uphuhliso lweenqwelo-moya. Ngokuhamba ngokukhawuleza kweteknoloji yeenqwelo-moya, iimfuno zezixhobo ziya ziba nzima ngakumbi, kungekuphela nje ngamandla aphezulu kunye noxinano oluphantsi, kodwa nakwimeko yokumelana nobushushu obuphezulu, ukumelana nokugqwala kweekhemikhali, ukugquma kombane kunye neempawu ze-dielectric kunye nezinye iinkalo zokusebenza okugqwesileyo.Ifayibha yeQuartzNgenxa yoko kuye kwavela izinto ezidityanisiweyo ze-silicone, kwaye ngokudibanisa kwazo iipropati ezikhethekileyo, ziye zaba ngamandla amatsha kwicandelo leenqwelomoya, zifaka amandla amatsha kuphuhliso lweenqwelomoya zanamhlanje.

Unyango lwangaphambi kwefayibha luphucula ukubopha
Unyango lwangaphambi kokulungiswa kweefayibha ze-quartz linyathelo elibalulekileyo ngaphambi kokudibanisa iifayibha ze-quartz nge-silicone resin. Ekubeni umphezulu weefayibha ze-quartz uhlala uthambile, nto leyo engayi kunceda ekubambeni okuqinileyo nge-silicone resin, umphezulu weefayibha ze-quartz unokutshintshwa ngonyango lweekhemikhali, unyango lwe-plasma kunye nezinye iindlela.
Ukwenziwa kweResin echanekileyo ukuhlangabezana neemfuno
Iiresini zesilicone kufuneka zenziwe ngokuchanekileyo ukuze zihlangabezane neemfuno ezahlukeneyo zokusebenza kwezinto ezidityanisiweyo kwiimeko ezahlukeneyo zokusetyenziswa kwicandelo leenqwelo moya. Oku kubandakanya uyilo olucokisekileyo kunye nohlengahlengiso lwesakhiwo semolekyuli yeresini yesilicone, kunye nokongezwa kwezixa ezifanelekileyo zeearhente zokuphilisa, ii-catalysts, izizalisi kunye nezinye izongezo.
Iinkqubo ezininzi zokubumba ukuqinisekisa umgangatho
Iinkqubo zokubumba eziqhelekileyo ze-quartz fiber silicone composites ziquka iResin Transfer Molding (RTM), iVacuum Assisted Resin Injection (VARI), kunye neHot Press Molding, nganye kuzo ineenzuzo zayo ezizodwa kunye nobubanzi bokusetyenziswa.
I-Resin Transfer Molding (RTM) yinkqubo apho i-Resin Transfer Molding ilungisiwe kwangaphambili.ifayibha ye-quartzI-preform ifakwa kwi-mold, ize i-silicone resin elungisiweyo ifakwe kwi-mold phantsi kwendawo yokungangeni ukuze ingene ngokupheleleyo kwi-fiber kunye ne-resin, ize ekugqibeleni inyangwe kwaye ibunjwe phantsi kobushushu obuthile kunye noxinzelelo.
Kwelinye icala, inkqubo yokufaka i-resin encediswa yi-vacuum, isebenzisa i-vacuum suction ukutsala i-resin kwiimolds ezigqunywe zii-quartz fibers ukuze kuphumeze umxube wee-fibers kunye ne-resin.
Inkqubo yokubumba ngoxinzelelo olushushu kukuxuba imicu ye-quartz kunye ne-silicone resin ngomlinganiselo othile, ibekwe kwi-mold, ize emva koko i-resin iqine phantsi kobushushu obuphezulu kunye noxinzelelo, ukuze kwenziwe izinto ezidityanisiweyo.
Emva konyango ukuze kuphuculwe iipropati zezinto eziphathekayo
Emva kokuba izinto ezidityanisiweyo zibunjiwe, uthotho lweenkqubo emva konyango, ezinje ngonyango lobushushu kunye nomatshini, ziyafuneka ukuphucula ngakumbi iimpawu zezinto kunye nokuhlangabezana neemfuno ezingqongqo zentsimi yeenqwelo moya. Unyango lobushushu lunokususa uxinzelelo oluseleyo ngaphakathi kwezinto ezidityanisiweyo, luphucule ukubopha phakathi kwefayibha kunye ne-matrix, kwaye luphucule uzinzo kunye nokuqina kwezinto. Ngokulawula ngokuchanekileyo iiparameter zonyango lobushushu ezifana nobushushu, ixesha kunye nesantya sokupholisa, ukusebenza kwezinto ezidityanisiweyo kunokulungiswa.
Inzuzo yokusebenza:

Amandla Aphezulu Acacileyo kunye Nokunciphisa Ubunzima BeModulus Ekhethekileyo
Xa kuthelekiswa nezinto zesinyithi zemveli, ii-silicone ze-quartz fiber composites zinezibonelelo ezibalulekileyo zamandla aphezulu athile (umlinganiselo wamandla ukuya kuxinano) kunye ne-modulus ephezulu ethile (umlinganiselo we-modulus ukuya kuxinano). Kwi-aerospace, ubunzima besithuthi yenye yezinto eziphambili ezichaphazela ukusebenza kwaso. Ukunciphisa ubunzima kuthetha ukuba ukusetyenziswa kwamandla kunokuncitshiswa, isantya sokubhabha sinyuswe, uluhlu kunye nomthwalo womthwalo unyuswe. Ukusetyenziswa kweifayibha ye-quartzIi-silicone resin composites zokwenza i-fuselage yeenqwelo moya, amaphiko, umsila kunye nezinye izinto zokwakha zinokunciphisa kakhulu ubunzima benqwelo moya phantsi kwesiseko sokuqinisekisa amandla nokuqina kwesakhiwo.

Iipropati ezilungileyo ze-dielectric ukuqinisekisa unxibelelwano kunye nokuhamba
Kwiteknoloji yeenqwelo-moya zanamhlanje, ukuthembeka kweenkqubo zonxibelelwano kunye nokuhamba kubaluleke kakhulu. Ngenxa yeempawu zayo ezilungileyo ze-dielectric, izinto ze-silicone ze-quartz fiber ziye zaba zizinto ezifanelekileyo zokwenza i-radome yeenqwelo-moya, i-antenna yonxibelelwano kunye nezinye izinto. Ii-Radomes kufuneka zikhusele i-antenna ye-radar kwindawo engaphandle kwaye kwangaxeshanye ziqinisekise ukuba amaza e-electromagnetic anokungena kakuhle nangokuchanekileyo adlulise imiqondiso. Iimpawu eziphantsi ze-dielectric ezingaguqukiyo kunye nezingaguqukiyo ze-quartz fiber silicone composites zinokunciphisa ngempumelelo ukulahleka kunye nokugqwetheka kwamaza e-electromagnetic kwinkqubo yokudlulisa, ukuqinisekisa ukuba inkqubo ye-radar ibona ngokuchanekileyo ithagethi kwaye ikhokela uhambo lwenqwelo-moya.
Ukumelana nokukhupha umoya kwiindawo eziyingozi kakhulu
Kwezinye iindawo ezikhethekileyo zenqwelo-moya, njengegumbi lokutsha kunye nomlomo wenjini yenqwelo-moya, njl.njl., kufuneka zimelane nobushushu obuphezulu kakhulu kunye nokutsha kwegesi. Ii-silicone ze-quartz fiber composites zibonisa ukumelana okuhle kakhulu nokukhupha umoya kwiindawo ezinobushushu obuphezulu. Xa umphezulu wezinto uchaphazeleka kubushushu obuphezulu, i-silicone resin iya kubola kwaye ibe yi-carbonize, yenze umaleko womaleko we-carbonize onefuthe lokuthintela ubushushu, ngelixa ii-fibers ze-quartz zikwazi ukugcina ukuqina kwesakhiwo kwaye ziqhubeke nokubonelela ngenkxaso yamandla kwizixhobo.

Iindawo zokusetyenziswa:
Uyilo lweFuselage kunye neWing Structure
Ii-silicone ze-quartz fiber compositeszithatha indawo yesinyithi semveli ekwenzeni ii-fuselage kunye namaphiko eenqwelo moya, nto leyo ekhokelela kwinguqu ebalulekileyo yesakhiwo. Iifreyimu ze-fuselage kunye nee-wing girders ezenziwe ngezi zixhobo zibonelela ngokunciphisa ubunzima obukhulu ngelixa zigcina amandla kunye nokuqina kwesakhiwo.
Ukulungiswa kwecandelo leenjini ze-Aero
I-Aero-injini yeyona nto iphambili kwinqwelo-moya, kwaye ukuphuculwa kokusebenza kwayo kubalulekile ekusebenzeni kwenqwelo-moya iyonke. Ii-silicone ze-quartz fiber ziye zasetyenziswa kwiindawo ezininzi ze-aero-injini ukuze kufezekiswe ukwenziwa ngcono kunye nokuphuculwa kokusebenza kwamalungu. Kwiindawo ezishushu zenjini, ezifana negumbi lokutsha kunye nee-turbine blades, ukumelana nobushushu obuphezulu kunye nokukrala kwezinto ezidityanisiweyo kunokuphucula ngokufanelekileyo ubomi benkonzo kunye nokuthembeka kwamalungu, kwaye kunciphise iindleko zokugcina injini.
