Inkqubo yokubumba isixa esithile se-prepreg kumgodi wokubumba wesinyithi wokubumba, ukusetyenziswa kocinezelo kunye nomthombo wobushushu ukuvelisa ubushushu obuthile kunye noxinzelelo ukuze i-prepreg kumgodi wokubumba ithambe ngenxa yobushushu, ukuhamba koxinzelelo, igcwele ukuhamba, izaliswe ngumgodi wokubumba kunye nokunyanga iimveliso zendlela yenkqubo.
Iinkqubo yokubumbaluphawulwa ngesidingo sokufudumeza kwinkqubo yokubumba, injongo yokufudumeza kukwenza i-prepreg resin ethambileyo iqukuqele, igcwele umngxuma wokungunda, kwaye ikhawulezise ukusabela kokunyanga kwe-resin matrix. Ngexesha lenkqubo yokuzalisa umgodi wokubumba nge-prepreg, kungekuphela nje i-resin matrix ehambayo, kodwa kunye nezinto eziqinisayo, kunyeintlakai-matrix kunye ne-fibers yokuqinisa izalise zonke iinxalenye ze-mold cavity ngaxeshanye.
Kuphela i-resin matrix viscosity inkulu kakhulu, kwaye ibhondi yomelele ngokwaneleyo ukuba ihambe kunye nemicu yokuqinisa, ngoko ke inkqubo yokubumba idinga uxinzelelo olukhulu lokubumba. Oku kufuna iimbumba zetsimbi ezinamandla aphezulu, ukuchaneka okuphezulu, kunye nokuxhathisa ukubola, kwaye kufuna ukusetyenziswa koxinzelelo olukhethekileyo olushushu ukulawula ubushushu bokubumba ukunyanga, uxinzelelo, ixesha lokubamba, kunye nezinye iiparameters zenkqubo.
Indlela yokubumba yokusebenza kakuhle kwemveliso, ukuchaneka kobungakanani bemveliso, kunye nokugqiba komphezulu, ngakumbi kwisakhiwo esintsonkothileyo semveliso yemathiriyeli edibeneyo inokubunjwa kanye, kwaye ayisayi konakalisa ukusebenza kwemveliso yezinto ezidibeneyo. Intsilelo yayo ephambili kukuba uyilo lokubumba kunye nokuvelisa kunzima ngakumbi, kwaye utyalo-mali lokuqala lukhulu. Nangona inkqubo yokubumba ineziphene ezingentla, i-moldinkqubo yokubumbaisabambe indawo ebalulekileyo kwinkqubo yokubumba izinto ezidibeneyo.
1. Ukulungiselela
Yenza umsebenzi omhle we-prepreg, ukubumba i-tooling molds, kunye neqhekeza lovavanyo lweziko lomsebenzi oxhasayo, kwaye ucoce i-mold kusetyenziso lokugqibela lwe-resin eseleyo, kunye ne-debris, ukugcina i-mold icocekile kwaye igudile.
2. Ukusika kunye nokubeka prepregs
Iya kwenziwa ibe yimveliso yecarbon fiber izinto eziluhlaza zilungile, prepreg emva kokuphumelela uphononongo, ukubala indawo yemathiriyeli ekrwada, imathiriyeli, inani lamaphepha, umaleko wezinto ezikrwada ngomaleko wesiqhumiso esongeziweyo, ngaxeshanye kwindawo ephezulu yesixhobo soxinzelelo lwangaphambili, lucinezelwe kwimilo yesiqhelo, umgangatho wenani elithile lamaqumrhu axineneyo.
3. Ukubumba kunye nokunyanga
Beka izinto ezikrwada ezipakishweyo kwi-mold, kwaye kwangaxeshanye kwiingxowa zomoya zeplastiki zangaphakathi, vala ukungunda, yonke into kumatshini wokubumba, ii-airbags zeplastiki zangaphakathi kunye noxinzelelo oluthile olungaguqukiyo, ubushushu obungaguqukiyo, seta ixesha elingaguqukiyo ukuze linyange.
4. Ukupholisa kunye nokudiliza
Emva kwexesha loxinzelelo ngaphandle ngundo kuqala ukubanda ukwazi ixesha elithile, uze uvule ngundo, demolding ngaphandle iliso ukucoca ngundo tooling.
5. Ukwenziwa kokubumba
Emva kokudiliza imveliso kufuneka ihlanjululwe, nge-brush yensimbi okanye ibrashi yobhedu ukukrazula iplastiki eseleyo, kunye nokuvuthela ngomoya oxinyiweyo, imveliso ebunjiweyo iyacolwa, ukuze umphezulu ube lula kwaye ucoceke.
6. Uvavanyo olungonakalisi kunye nokuhlolwa kokugqibela
Uvavanyo olungonakalisi kunye nokuhlolwa kokugqibela kweemveliso zenziwa ngokweemfuno zamaxwebhu oyilo.
Ukususela ekuzalweni kwei-carbon fiber composites, ehlala inqunyanyiswa yindleko yokuvelisa kunye nokubethelwa kwemveliso, ayizange isetyenziswe ngobuninzi. Isigqibo seendleko zokuvelisa i-carbon fiber kunye nokubetha yinkqubo yokubumba, inkqubo yokubumba i-carbon fiber composite kukho ezininzi, ezifana ne-RTM, i-VARI, itanki ye-hot press, i-oven curing prepreg (OOA), njl. 2, ixabiso liyabiza (xa kuthelekiswa nentsimbi kunye neplastiki). Inkqubo yokubumba i-Prepreg, njengohlobo lwenkqubo yokubumba, inokuqonda imveliso ye-batch kunye nokunciphisa iindleko zemveliso, ezisetyenziswa ngokubanzi nangaphezulu.
