(1) Iimveliso zezinto ezisebenzayo zokushisa ubushushu
Iindlela eziphambili zenkqubo yemveli ye-aerospace ephezulu yokusebenza kwesakhiwo esisebenzayo esidibeneyoizinto zokukhusela ukushisaare RTM (Resin Transfer Molding), ukubumba, kunye nokubeka, njl. Le projekthi ithatha inkqubo entsha yokubumba.
Ukuqhubekeka kwe-RTM:
① Ukubekwa kwelaphu lefiber: ilaphu lefiber yequartz elungisiweyo ifakwa kumgodi wokungunda ngaxeshanye;
② Isitofu se-resin: I-resin kunye ne-catalyst ixutywe kwi-static mixer ngaphambili kwi-injection gun kwaye ifakwe kumgodi wokungunda ogqunywe ngelaphu lefayibha.
③ Ukunyanga intlaka: umgodi wokungunda uyafudunyezwa ukuze kukhawuleziswe ukunyangwa kwentlaka;
(iv) Ukwenziwa kwemveliso: Emva kokuba i-resin iphiliswe kwaye ibunjwe, isikhunta sivulwa ukuze sifumane inxalenye yokugqibela edibeneyo.
Emva kwenkqubo ye-RTM (i-Resin Transfer Molding), i-quartz fiber cloth icutshungulwa kwaye ibekwe kunye negobolondo yensimbi, kwaye imveliso emva kokuba isethi ifanelekile emva kovavanyo lokusebenza, oluyimveliso egqityiweyo.

(2)Izixhobo ezidityanisiweyo ezibonisa amaza
I-quartz fiber iqinisiweiicomposites ceramic wave-transparent ezilungiselelwe yi-organic precursor impregnation cracking method (PIP) .Indlela yePIP kukusebenzisa i-organic precursor impregnated fiber preforms, kwaye emva koko i-pyrolysis, ukuveliswa kwe-quartz fiber matrix efakwe kwi-preform blanks kwi-billet, kwi-billet emva kokutshiza unyango lokupeyinta ukufaneleka kokuhlolwa kwemveliso, ukuba ukuhlolwa kunye nokugqiba imveliso. Ukuze kuqinisekiswe ukuba umphezulu wezinto zobushushu obufunekayo ugxininiso ungaphantsi kakhulu kunenkqubo yemveli yokutshiza ishushu, inokunciphisa umonakalo kwimicu yequartz, kwaye ineempawu zokubunjwa kwe-net-net, ngakumbi ilungele ukulungiswa kwezixhobo zemathiriyeli ezibonisa ubungakanani obukhulu be-wave-transparent.

(3) Izinto ezikhethekileyo zokugquma
Iilaphu lefiber yequartziya kulungiswa kumgodi wokungunda, i-resin iya kugalelwa kumgodi wokungunda ukuze igcwale i-fiber cloth mold cavity, ukufudumeza umngxunya wokungunda ukuze kukhawuleziswe ukunyangwa kwe-resin, ukunyangwa kwe-resin, ukuvula ukubumba kwaye kunokufumana izixhobo zokugqibela ezikhethekileyo zokukhusela.
