iindaba

Kwintsimi ye-aviation, ukusebenza kwezinto eziphathekayo kuhambelana ngokuthe ngqo nokusebenza, ukhuseleko kunye nophuhliso olunokwenzeka lweenqwelo-moya. Ngenkqubela phambili ekhawulezayo yetekhnoloji yezomoya, iimfuno zemathiriyeli ziya ziba ngqongqo ngakumbi, kungekuphela nje ngamandla aphezulu kunye noxinaniso oluphantsi, kodwa nakwizinga eliphezulu lokumelana nobushushu, ukumelana nemichiza, ukugqunywa kombane kunye neempawu zedielectric kunye neminye imiba yokusebenza kakuhle.I-quartz fiberiikompositi ze-silicone ziye zavela ngenxa yoko, kwaye kunye nendibaniselwano yazo ekhethekileyo yeepropati, ziye zaba yinto entsha kwintsimi ye-aviation, ifake amandla amatsha ekuphuhliseni izithuthi ze-aviation zanamhlanje.

I-Fiber Pretreatment iphucula iBonding
Unyango lwangaphambili lwemicu ye-quartz linyathelo elibalulekileyo ngaphambi kokudibanisa imicu ye-quartz kunye ne-silicone resin. Ekubeni ubuso be-quartz fibers buhlala bugudileyo, obungenakulungelelaniswa ngokuqinileyo kunye ne-silicone resin, umphezulu we-quartz fibers unokuguqulwa ngonyango lwamachiza, unyango lwe-plasma kunye nezinye iindlela.
Uqulunqo lweResin oluchanekileyo lokuhlangabezana neemfuno
Iireyini ze-silicone kufuneka zenziwe ngokuchanekileyo ukuze zihlangabezane neemfuno ezahlukeneyo zokusebenza kwezinto ezidibeneyo zokusetyenziswa kweemeko ezahlukeneyo zokusetyenziswa kwintsimi ye-aerospace. Oku kubandakanya ukuyila ngokucokisekileyo kunye nokulungelelaniswa kwesakhiwo se-molecular ye-silicone resin, kunye nokongezwa kweemali ezifanelekileyo zokuphilisa, i-catalysts, iifayili kunye nezinye izongezo.
Iinkqubo zokuBumba ezininzi zokuqinisekisa uMgangatho
Iinkqubo eziqhelekileyo zokubumba i-quartz fiber silicone composite zibandakanya i-Resin Transfer Molding (RTM), i-Vacuum Assisted Resin Injection (VARI), kunye ne-Hot Press Molding, nganye ineenzuzo zayo ezizodwa kunye nobubanzi bokusetyenziswa.
I-Resin Transfer Molding (RTM) yinkqubo apho i-pre-treatedi-quartz fiberi-preform ifakwe kwi-mold, kwaye i-resin elungiselelwe abicah ifakwe kwi-mold phantsi kwendawo ye-vacuum ukuze ingene ngokupheleleyo kwi-fiber nge-resin, kwaye ekugqibeleni iphiliswe kwaye ibunjwe phantsi kobushushu obuthile kunye noxinzelelo.
Inkqubo yokutofa i-vacuum-assisted resin, kwelinye icala, isebenzisa i-vacuum suction ukutsala i-resin kwi-mold egqunywe nge-quartz fibers ukuqonda i-composite ye-fibers kunye ne-resin.
Inkqubo yokubumba i-hot compression kukuxuba i-quartz fibers kunye ne-silicone resin kumlinganiselo othile, ifakwe kwi-mold, kwaye emva koko wenze i-resin iphilise phantsi kobushushu obuphezulu kunye noxinzelelo, ukwenzela ukuba yenze into edibeneyo.
Emva kokunyanga ukugqibelela iipropati eziphathekayo
Emva kokuba izinto ezidibeneyo zibunjwe, uchungechunge lweenkqubo zonyango emva kokunyanga, njengonyango lokushisa kunye nomatshini, ziyadingeka ukuze kuphuculwe ngakumbi izinto eziphathekayo kunye nokuhlangabezana neemfuno eziqinileyo zentsimi ye-aviation. Ukunyangwa kobushushu kunokuphelisa uxinzelelo olushiyekileyo ngaphakathi kwezinto ezidibeneyo, ukuphucula ukuhlangana phakathi kwefiber kunye ne-matrix, kunye nokuphucula ukuzinza kunye nokuqina kwezinto. Ngokulawula ngokuchanekileyo iiparitha zonyango lokushisa njengeqondo lokushisa, ixesha kunye nesantya sokupholisa, ukusebenza kwezinto ezidibeneyo kunokulungiswa.
Inzuzo yokusebenza:

Amandla aKhethekileyo aphezulu kunye nokuNcitshiswa kobunzima beModulus ePhakamileyo
Xa kuthelekiswa nezixhobo zetsimbi zemveli, i-quartz fibre silicone compotes ineenzuzo ezibalulekileyo zamandla athile aphezulu (umlinganiselo wamandla kuxinaniso) kunye nemodulus ethile ephezulu (umlinganiselo wemodulus ukuya kuxinaniso). Kwi-aerospace, ubunzima besithuthi yenye yezinto eziphambili ezichaphazela ukusebenza kwayo. Ukunciphisa ubunzima kuthetha ukuba ukusetyenziswa kwamandla kunokuncitshiswa, isantya sokuhamba ngenqwelomoya sanyuswa, uluhlu kunye nomthwalo wokuhlawula. Ukusetyenziswa kwei-quartz fiberi-silicone resin composites ukwenza i-fuselage yenqwelomoya, amaphiko, umsila kunye nezinye izinto ezisisiseko zinokunciphisa kakhulu ubunzima benqwelomoya phantsi kwesiseko sokuqinisekisa ukomelela kunye nokuqina kwesakhiwo.

Iimpawu ezilungileyo ze-dielectric zokuqinisekisa unxibelelwano kunye nokuhamba
Kubuchwephesha bezophapho bale mihla, ukuthembeka konxibelelwano kunye neenkqubo zokuqhuba inqanawa kubalulekile. Ngeempawu zayo ezilungileyo ze-dielectric, i-quartz fiber silicone composite material iye yaba yinto efanelekileyo yokwenza i-radome yeenqwelomoya, i-antenna yonxibelelwano kunye nezinye izinto. IiRadomes kufuneka zikhusele i-antenna ye-radar kwindawo yangaphandle kwaye kwangaxeshanye iqinisekise ukuba amaza e-electromagnetic anokungena ngokutyibilikayo nangokuchanekileyo ukuhambisa imiqondiso. I-dielectric ephantsi rhoqo kunye ne-tangent ephantsi yelahleko yeempawu ze-quartz fibre silicone composite inokunciphisa ngokufanelekileyo ilahleko kunye nokuphazamiseka kwamaza e-electromagnetic kwinkqubo yokuhambisa, ukuqinisekisa ukuba inkqubo ye-radar ifumanisa ngokuchanekileyo ekujoliswe kuyo kwaye ikhokela indiza yendiza.
Ukuchasana nokuchithwa kweemeko ezingqongileyo ezigqithisileyo
Kwezinye iindawo ezikhethekileyo zenqwelomoya, ezifana negumbi lokutsha kunye nomlomo wenjini yenqwelomoya, njl.njl., kufuneka zimelane nobushushu obuphezulu kakhulu kunye nokugungxulwa kwegesi. Imidibaniso ye-silicone yefiber ye-quartz ibonisa ukuxhathisa okugqwesileyo kokukhupha umoya kwindawo yobushushu obuphezulu. Xa ubuso bezinto eziphathekayo buxhomekeke kwimpembelelo yomlilo ophezulu, i-silicone resin iya kubola kunye ne-carbonize, yenza umaleko we-carbonized layer kunye ne-heat-insulating effect, ngelixa i-quartz fibers iyakwazi ukugcina ingqibelelo yesakhiwo kwaye iqhubeke nokubonelela ngenkxaso yamandla kwizinto eziphathekayo.

Iindawo zokuSebenza:
I-Fuselage kunye ne-Wing Structural Innovation
Iimpawu ze-silicone ze-quartz fiberbathatha indawo yesinyithi semveli ekwenzeni iifuselage zenqwelomoya kunye namaphiko, okukhokelela kutshintsho olubalulekileyo lwesakhiwo. Iifreyimu ze-Fuselage kunye nama-wing girders ezenziwe kula ma-composites zinika ukunciphisa ubunzima obubalulekileyo ngelixa ugcina amandla okwakhiwa kunye nokuqina.
Ukulungiswa kwecandelo le-injini yomoya
I-aero-injini yeyona nto ingundoqo kwinqwelo-moya, kwaye ukuphuculwa kokusebenza kwayo kubalulekile ekusebenzeni kwenqwelo-moya iyonke. I-Quartz fiber silicone composites isetyenziswe kwiindawo ezininzi ze-aero-injini ukufezekisa ukulungiswa kunye nokuphucula ukusebenza kwamalungu. Kwiindawo ezitshisayo ze-injini, ezifana negumbi lokutsha kunye nee-turbine blades, ubushushu obuphezulu be-composite kunye nokuxhatshazwa kwe-abrasion kunokuphucula ngokufanelekileyo ubomi benkonzo kunye nokuthembeka kwamacandelo, kunye nokunciphisa iindleko zokugcina injini.
