Mu gawo la ndege, magwiridwe antchito a zipangizo amagwirizana mwachindunji ndi magwiridwe antchito, chitetezo ndi kuthekera kwa chitukuko cha ndege. Chifukwa cha kupita patsogolo mwachangu kwa ukadaulo wa ndege, zofunikira pa zipangizo zikukulirakulira, osati kokha ndi mphamvu yayikulu komanso kupsinjika kochepa, komanso kukana kutentha kwambiri, kukana dzimbiri la mankhwala, kutchinjiriza magetsi ndi mphamvu zamagetsi ndi zina mwazinthu zabwino kwambiri.Ulusi wa quartzZotsatira zake n'zakuti zinthu zopangidwa ndi silicone zatulukira, ndipo chifukwa cha kuphatikiza kwawo kwapadera kwa zinthu, zakhala mphamvu zatsopano pankhani ya ndege, zomwe zawonjezera mphamvu zatsopano pakupanga magalimoto amakono oyendetsa ndege.

Kuchiza Ulusi Pasadakhale Kumathandiza Kugwirizana
Kukonza ulusi wa quartz musanayambe ndi gawo lofunika kwambiri musanaphatikize ulusi wa quartz ndi silicone resin. Popeza pamwamba pa ulusi wa quartz nthawi zambiri pamakhala posalala, zomwe sizikugwirizana bwino ndi silicone resin, pamwamba pa ulusi wa quartz pakhoza kusinthidwa kudzera mu mankhwala, chithandizo cha plasma ndi njira zina.
Kupanga Resin Koyenera Kuti Kukwaniritse Zosowa
Ma resini a silicone ayenera kupangidwa molondola kuti akwaniritse zofunikira zosiyanasiyana zogwirira ntchito pazinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito m'munda wa ndege. Izi zimaphatikizapo kupanga mosamala ndi kusintha kapangidwe ka mamolekyu a resini ya silicone, komanso kuwonjezera kuchuluka koyenera kwa zinthu zochiritsa, zoyambitsa, zodzaza ndi zina zowonjezera.
Njira Zambiri Zopangira Ubwino
Njira zodziwika bwino zopangira zinthu zopangidwa ndi silicone zopangidwa ndi quartz fiber zimaphatikizapo Resin Transfer Molding (RTM), Vacuum Assisted Resin Injection (VARI), ndi Hot Press Molding, iliyonse ili ndi ubwino wake wapadera komanso momwe imagwiritsidwira ntchito.
Kuumba kwa Resin Transfer (RTM) ndi njira yomwe mankhwala oyeretsera asanayambe kukonzedwa.ulusi wa quartzPreform imayikidwa mu nkhungu, kenako silicone resin yokonzedwayo imalowetsedwa mu nkhungu pansi pa malo opanda mpweya kuti ilowetse ulusi wonse ndi utomoni, kenako kenako imachiritsidwa ndikuwumbidwa pansi pa kutentha ndi kupanikizika kwina.
Njira yojambulira utomoni pogwiritsa ntchito vacuum-assisted resin, kumbali ina, imagwiritsa ntchito vacuum suction kuti ikoke utomoniwo mu nkhungu zomwe zili ndi ulusi wa quartz kuti zipange ulusi ndi utomoni wosakanikirana.
Njira yopangira zinthu zotentha ndi kusakaniza ulusi wa quartz ndi silicone resin mu gawo linalake, ndikuyika mu nkhungu, kenako ndikupanga utomoni wouma pansi pa kutentha kwakukulu ndi kupanikizika, kuti apange zinthu zophatikizika.
Kukonza zinthu pambuyo pa chithandizo kuti zinthuzo zikhale bwino
Pambuyo poti zinthu zopangidwa ndi zinthu zosiyanasiyana zapangidwa, njira zingapo zochizira pambuyo pake, monga kutentha ndi makina, zimafunika kuti zinthuzo ziwongolere bwino ndikukwaniritsa zofunikira za ndege. Kuchiza kutentha kumatha kuchotsa kupsinjika komwe kulipo mkati mwa zinthu zopangidwa ndi zinthu zosiyanasiyana, kukulitsa mgwirizano pakati pa ulusi ndi matrix, ndikuwonjezera kukhazikika ndi kulimba kwa zinthuzo. Mwa kuwongolera bwino magawo a kutentha monga kutentha, nthawi ndi liwiro lozizira, magwiridwe antchito a zinthu zopangidwa ndi zinthu zosiyanasiyana amatha kukonzedwa bwino.
Ubwino wa Kuchita:

Mphamvu Yaikulu Kwambiri ndi Kuchepetsa Kulemera kwa Modulus Yaikulu Kwambiri
Poyerekeza ndi zipangizo zachitsulo zachikhalidwe, ma silicone a quartz fiber ali ndi ubwino waukulu wa mphamvu yeniyeni (chiŵerengero cha mphamvu ndi kuchulukana) ndi modulus yeniyeni (chiŵerengero cha modulus ndi kuchulukana). Mu ndege, kulemera kwa galimoto ndi chimodzi mwa zinthu zofunika kwambiri zomwe zimakhudza magwiridwe antchito ake. Kuchepetsa kulemera kumatanthauza kuti kugwiritsa ntchito mphamvu kumatha kuchepetsedwa, liwiro la ndege likuwonjezeka, kutalika ndi katundu wokwera zikuwonjezeka. Kugwiritsa ntchitoulusi wa quartzZopangira silicone resin zopangira fuselage ya ndege, mapiko, mchira ndi zinthu zina zomangira ndege zimatha kuchepetsa kwambiri kulemera kwa ndegeyo chifukwa cha kutsimikiza kuti kapangidwe kake ndi kolimba.

Katundu wabwino wa dielectric kuti atsimikizire kulumikizana ndi kuyenda
Mu ukadaulo wamakono wa ndege, kudalirika kwa njira zolumikizirana ndi zoyendera ndikofunikira kwambiri. Ndi mphamvu zake zabwino za dielectric, zinthu zopangidwa ndi silicone ya quartz fiber zakhala chinthu chabwino kwambiri chopangira radome ya ndege, antenna yolumikizirana ndi zinthu zina. Radomes amafunika kuteteza antenna ya radar ku chilengedwe chakunja komanso nthawi yomweyo kuonetsetsa kuti mafunde amagetsi amatha kulowa bwino komanso molondola. Makhalidwe otsika a dielectric constant komanso otsika a tangent tangent a quartz fiber silicone composites amatha kuchepetsa bwino kutayika ndi kusokonekera kwa mafunde amagetsi munjira yotumizira, kuonetsetsa kuti radar system imazindikira molondola cholinga ndikuwongolera ndege.
Kukana kwa ablation m'malo ovuta kwambiri
M'malo ena apadera a ndege, monga chipinda choyaka moto ndi nozzle ya injini ya ndege, ndi zina zotero, amafunika kupirira kutentha kwambiri komanso kusungunuka kwa mpweya. Ma silicone opangidwa ndi ulusi wa quartz amasonyeza kukana bwino kwambiri kwa ablation m'malo otentha kwambiri. Pamene pamwamba pa chinthucho payaka moto wotentha kwambiri, silicone resin imawola ndi kupanga carbonization, ndikupanga wosanjikiza wa carbonized wosanjikiza wokhala ndi mphamvu yoteteza kutentha, pomwe ulusi wa quartz umatha kusunga mawonekedwe ake ndikupitiliza kupereka chithandizo champhamvu cha chinthucho.

Kupangidwa kwa Kapangidwe ka Fuselage ndi Mapiko
Zosakaniza za silicone za Quartz fiberakulowa m'malo mwa zitsulo zachikhalidwe popanga ma fuselage ndi mapiko a ndege, zomwe zikupangitsa kuti pakhale zatsopano zambiri. Mafelemu a fuselage ndi ma girders a mapiko opangidwa kuchokera ku zinthuzi amapereka kuchepetsa kulemera kwakukulu pamene akusunga mphamvu ndi kuuma kwa kapangidwe kake.
Kukonza bwino kwa zigawo za injini ya Aero
Injini ya Aero ndiye gawo lalikulu la ndege, ndipo kusintha kwa magwiridwe ake ndikofunikira kwambiri pakugwira ntchito konse kwa ndege. Ma silicone a Quartz fiber agwiritsidwa ntchito m'malo ambiri a injini ya aero kuti akwaniritse bwino komanso kukonza magwiridwe antchito a ziwalozo. M'malo otentha a injini, monga chipinda choyaka moto ndi masamba a turbine, kukana kutentha kwambiri ndi kupsinjika kwa zinthu zomwe zimapangidwa ndi zinthuzi kumatha kusintha moyo wautumiki ndi kudalirika kwa ziwalozo, ndikuchepetsa mtengo wosamalira injini.
