The akamaumba ndondomeko ndi kuchuluka kwa prepreg mu zitsulo nkhungu patsekeke wa nkhungu, ntchito makina osindikizira ndi kutentha gwero kutulutsa ena kutentha ndi kuthamanga kuti prepreg mu nkhungu patsekeke ndi wofewetsa ndi kutentha, kuthamanga otaya, wodzaza ndi otaya, wodzazidwa ndi nkhungu patsekeke akamaumba ndi kuchiritsa mankhwala a ndondomeko njira.
Thekuumba ndondomekoimadziwika ndi kufunikira kwa kutentha pakuumba, cholinga chotenthetsera ndikupangitsa kuti prepreg utomoni wofewetsa utuluke, wodzaza ndi nkhungu, ndikufulumizitsa momwe machiritso amachitidwe a utomoni wa matrix. Panthawi yodzaza nkhungu ndi prepreg, osati utomoni wokhawokha umayenda, komanso zinthu zolimbitsa, ndiutomonimatrix ndi ulusi wolimbitsa amadzaza mbali zonse za nkhungu nthawi imodzi.
Kukhuthala kwa utomoni wokhawokha ndi waukulu kwambiri, ndipo chomangiracho ndi champhamvu kwambiri kuti chizitha kuyenda ndi ulusi wolimbitsa, kotero kuumba kumafunikira kukakamiza kokulirapo. Izi zimafuna nkhungu zachitsulo zokhala ndi mphamvu zambiri, zolondola kwambiri, komanso kukana kwa dzimbiri, ndipo zimafuna kugwiritsa ntchito makina osindikizira apadera otentha kuti athetse kutentha kwa kuchiritsa kuumba, kupanikizika, kusunga nthawi, ndi zina za ndondomeko.
The akamaumba njira ya dzuwa mkulu, mankhwala kukula kulondola, ndi pamwamba mapeto, makamaka dongosolo zovuta za gulu zinthu zakuthupi akhoza zambiri kuumbidwa kamodzi, ndipo sizidzawononga ntchito ya gulu zinthu zakuthupi. Cholakwika chake chachikulu ndikuti mapangidwe a nkhungu ndi kupanga zimakhala zovuta kwambiri, ndipo ndalama zoyamba zimakhala zazikulu. Ngakhale kuti akamaumba ali ndi zofooka pamwamba, nkhungukuumba ndondomekoakadali ndi udindo wofunikira pakupanga zinthu zambiri.
1. Kukonzekera
Chitani ntchito yabwino ya prepreg, akamaumba tooling zisamere pachakudya, ndi ng'anjo mayeso chidutswa cha ntchito yothandizira, ndi kuyeretsa nkhungu mu ntchito yotsalira utomoni wotsalira, ndi zinyalala, kusunga nkhungu woyera ndi yosalala.
2. Kudula ndi kuika prepregs
Adzapangidwa kukhala mankhwala a carbon CHIKWANGWANI zopangira zokonzeka, prepreg atatha kubwereza, kuwerengera dera la zipangizo, zipangizo, chiwerengero cha mapepala, zopangira wosanjikiza ndi wosanjikiza zofukiza anawonjezera, nthawi yomweyo pa superposition wa zinthu za pre-pressure, mbamuikha mu mawonekedwe a wokhazikika, khalidwe la chiwerengero cha wandiweyani mabungwe.
3. Kuumba ndi kuchiritsa
Ikani zopangira zopangira mu nkhungu, ndipo nthawi yomweyo m'matumba apulasitiki amkati, kutseka nkhungu, zonse mu makina opangira, ma airbags apulasitiki amkati kuphatikiza kupanikizika kosalekeza, kutentha kosalekeza, khazikitsani nthawi yokhazikika kuti ichiritse.
4. Kuziziritsa ndi kugwetsa
Patapita nthawi ya mavuto kunja nkhungu choyamba ozizira kudziwa kwa nthawi, ndiyeno kutsegula nkhungu, demolding kunja diso kuyeretsa tooling nkhungu.
5. Processing akamaumba
Pambuyo pogwetsa mankhwalawo ayenera kutsukidwa, ndi burashi yachitsulo kapena burashi yamkuwa kuti achotse pulasitiki yotsalira, ndikuwomba ndi mpweya woponderezedwa, mankhwala opangidwawo amapukutidwa, kuti pamwamba pakhale bwino komanso oyera.
6. Kuyesa kosawonongeka ndi kuyendera komaliza
Kuyesa kosawononga ndikuwunika komaliza kwa zinthuzo kumachitika molingana ndi zofunikira za zolemba zopanga.
Kuyambira kubadwa kwakaboni fiber kompositi, yomwe nthawi zonse imachepetsedwa ndi mtengo wopangira ndi kugunda kwa kupanga, sikunagwiritsidwe ntchito mochuluka. Chisankho cha mtengo wa carbon fiber kupanga ndi kugunda ndi njira yopangira, carbon fiber composite material composite process pali zambiri, monga RTM, VARI, tank yotentha yosindikizira, uvuni kuchiritsa prepreg (OOA), ndi zina zotero, koma pali zopinga ziwiri: 1, nthawi yozungulira yozungulira ndi yaitali; 2, mtengo wake ndi wokwera mtengo (poyerekeza ndi zitsulo ndi pulasitiki). Prepreg akamaumba ndondomeko, monga mtundu wa akamaumba ndondomeko, akhoza kuzindikira mtanda kupanga ndi kuchepetsa mtengo kupanga, amene kwambiri ndi ambiri ambiri.
