(1) Iimveliso zezinto ezisebenzayo zokukhusela ubushushu
Iindlela eziphambili zenkqubo yendabuko ye-aerospace esebenza kakuhle kakhulu, imisebenzi yesakhiwo edibeneyoizixhobo zokukhusela ubushushuyi-RTM (Resin Transfer Molding), ukubumba, kunye ne-layup, njl. Le projekthi yamkela inkqubo entsha yokubumba emininzi.
Ukucutshungulwa kwe-RTM:
① Ukubeka ilaphu lefayibha: ilaphu lefayibha ye-quartz elilungisiweyo lifakwa kwindawo yokubumba ngaxeshanye;
② Inaliti yeresin: iresin kunye ne-catalyst zixutywa kwi-mixer engashukumiyo ngaphambili kwesibhamu se-injection kwaye zifakwe kwi-mold cavity egqunywe ngelaphu lefayibha.
③ Ukulungiswa kweresin: umngxuma wokubumba uyafudunyezwa ukuze kukhawuleziswe ukwenziwa kweresin;
(iv) Ukususwa kwemveliso: Emva kokuba i-resin ilungisiwe kwaye ibunjiwe, isikhunta siyavulwa ukuze kufunyanwe icandelo lokugqibela elihlanganisiweyo.
Emva kwenkqubo ye-RTM (Resin Transfer Molding), ilaphu le-quartz fiber liyacutshungulwa lize libekwe ngeqokobhe lesinyithi, kwaye imveliso emva kweseti iyafaneleka emva kovavanyo lokusebenza, oluyimveliso egqityiweyo.

(2) Izinto ezidityanisiweyo ezibonakalayo ngamaza
Ifayibha yeQuartz eqinisiweyoIi-composites ze-ceramic-transparent wave ezilungiselelwe yindlela yokuqhekeka kwe-organic precursor impregnation (PIP). Indlela ye-PIP kukusebenzisa ii-precursor ze-organic precursor impregnated fiber preforms, emva koko i-pyrolysis, ukuveliswa kwe-quartz fiber matrix efakwe kwi-preform blanks kwi-billet, kwi-billet emva kokupenda i-spray unyango lokuhlola, ukuhlola kunye nokufaneleka kwayo, oko kukuthi imveliso egqityiweyo. Ukuqinisekisa ukuba umphezulu wezinto ezifunekayo zobushushu boxinzelelo olufunekayo uphantsi kakhulu kunenkqubo yesiqhelo yokunyibilikisa i-hot press, kunokunciphisa umonakalo kwii-fibers ze-quartz, kwaye uneempawu zokubumba i-near-net, ezifanelekileyo ngakumbi ekulungiseleleni izinto ezinkulu ze-wave-transparent material.

(3) Izixhobo zokukhusela ezikhethekileyo
Iilaphu lefayibha ye-quartzIza kulungiswa kwingxobo yesikhunta, i-resin iza kufakwa kwingxobo yesikhunta ukuze izaliswe yingxobo yelaphu lefayibha, ifudumale ingxobo yesikhunta ukuze ikhawulezise ukucocwa kwe-resin, i-resin icoca, ivule i-mold kwaye ifumane izixhobo zokusebenza ezikhethekileyo zokugqibela zokukhusela.
