(1) Imikhiqizo yezinto ezibonakalayo ezivikela ukushisa
Izindlela eziyinhloko zenqubo yendabuko ye-aerospace yokusebenza kwesakhiwo sokusebenza okuphezulu okuhlanganisiweizinto zokuvikela ukushisakukhona i-RTM (I-Resin Transfer Molding), ukubumba, nokuhlelwa, njll. Le phrojekthi isebenzisa inqubo entsha yokubumba eminingi.
I-RTM Iyacubungula:
① Ukubekwa kwendwangu ye-fiber: indwangu ye-quartz fiber elungisiwe ifakwa emgodini wokukhunta ngesikhathi esisodwa;
② Umjovo we-resin: i-resin kanye ne-catalyst ixutshwa kumxube omile ngaphambili kwesibhamu somjovo bese kufakwa emgodini wokubunjwa ombozwe ngendwangu yefayibha.
③ Ukwelashwa kwe-resin: isikhunta siyashiswa ukuze kusheshiswe ukuphulukiswa kwe-resin;
(iv) Ukwakhiwa komkhiqizo: Ngemva kokuba i-resin ilashwa futhi ibunjwe, isikhunta sivulwa ukuze kutholwe ingxenye yokugcina eyinhlanganisela.
Ngemuva kwenqubo ye-RTM (Resin Transfer Molding), indwangu ye-quartz fiber iyacutshungulwa futhi isethwe ngegobolondo lensimbi, futhi umkhiqizo ngemva kwesethi ufanelekile ngemva kokuhlolwa kokusebenza, okuwumkhiqizo oqediwe.

(2)Izinto eziyinhlanganisela zamagagasi ezibonisa ngale
I-quartz fiber iqinisiweizinhlanganisela ze-ceramic wave-transparent ezilungiselelwe indlela ye-organic precursor impregnation cracking (PIP) .Indlela ye-PIP ukusebenzisa i-organic precursor impregnated fiber preforms, bese i-pyrolysis, ukukhiqizwa kwe-quartz fibre matrix efakwe ezikhaleni ze-preform ku-billet, ku-billet ngemva kokwelashwa kokupenda kwesifutho ukuze kuhlolwe umkhiqizo wawo, lokho kuwukuhlola kanye nokuqedwa kokuhlolwa komkhiqizo. Ukuze kuqinisekiswe ukuthi indawo engaphezulu yezinga lokushisa elidingekayo le-densification iphansi kakhulu kunenqubo yendabuko yomshini wokushisa oshisayo, inganciphisa umonakalo emicu ye-quartz, futhi inezici zokubunjwa kwenethi eseduze, elungele ukulungiswa kwezingxenye zezinto ezibonakalayo ezinosayizi omkhulu wamagagasi.

(3) Izinto ezikhethekile zokufaka ugesi
Iindwangu ye-quartz fiberizolungiselelwa emgodini wesikhunta, i-resin izofakwa emgodini wesikhunta ukuze igcwale i-fiber cloth mold cavity, ukushisa i-mold cavity ukuze kusheshiswe ukuphulukiswa kwe-resin, ukubunjwa kwe-resin ukuphulukisa, ukuvula isikhunta futhi kungathola okokugcina okukhethekile okusebenzayo okusebenzayo.
