1. Kuumba kwa Dzanja

Kumanga kwa manja ndi njira yachikhalidwe yopangira ma flanges a fiberglass-reinforced plastic (FRP). Njira imeneyi imaphatikizapo kuika pamanja utomoni-impregnatednsalu ya fiberglasskapena mphasa mu nkhungu ndi kuwalola kuchiza. Njira yeniyeni ndi iyi: Choyamba, chingwe chamkati chokhala ndi utomoni wamkati chimapangidwa pogwiritsa ntchito utomoni ndi nsalu za fiberglass. Pambuyo pochiza liner, amachotsedwa mu nkhungu, ndipo mapangidwe apangidwe amapangidwa. Kenako utomoni umatsukidwa pamwamba pa nkhungu ndi chingwe chamkati. Zigawo zansalu za fiberglass zodulidwa zisanakhale zimayikidwa molingana ndi dongosolo losanjikiza lokonzedweratu, ndi gawo lililonse lopangidwa ndi chodzigudubuza kuti liwonetsetse kuti kulowetsedwa bwino. Pamene makulidwe ofunidwa akwaniritsidwa, msonkhanowo umachiritsidwa ndikugwetsedwa.

Utoto wa matrix wopangira zoyika manja nthawi zambiri umagwiritsa ntchito poliyesitala ya epoxy kapena unsaturated, pomwe chowonjezera chimakhala chapakati-alkali kapenansalu ya fiberglass yopanda alkali.

Ubwino: Zofunikira pazida zotsika, kuthekera kopanga ma flange osakhala wamba, komanso palibe zoletsa pa geometry ya flange.

Zoipa: Kuphulika kwa mpweya komwe kumapangidwa panthawi yochiritsa utomoni kungayambitse porosity, kuchepetsa mphamvu zamakina; otsika kupanga dzuwa; ndi kutsirizitsa kosagwirizana, kosayengedwa pamwamba.

2. Compression Kuumba

Kumangirira kumaphatikizapo kuyika kuchuluka kwa zinthu zomwe zimapangidwira mu nkhungu ya flange ndikuchiza mopanikizika pogwiritsa ntchito makina osindikizira. Zipangizo zomangira zimasiyanasiyana ndipo zingaphatikizepo ulusi wosakanizidwa kapena woikidwiratu wodulidwa waufupi, zinyalala za nsalu za fiberglass zobwezerezedwanso, mphete za nsalu za magalasi ambiri osanjikiza, mapepala a SMC (mapepala omangira ma sheet), kapena ma preforms a nsalu ya fiberglass yowombedwa kale. Mwanjira iyi, flange disk ndi khosi zimapangidwira nthawi imodzi, kupititsa patsogolo mphamvu zamagulu ndi kukhulupirika kwapangidwe.

Ubwino: Kulondola kwapamwamba kwambiri, kubwerezabwereza, kukwanira kwa kupanga makina ambiri, luso lopanga ma flanges ovuta a khosi mu sitepe imodzi, ndi malo osalala bwino omwe safuna kukonzanso pambuyo pake.

Zoipa: Kukwera mtengo kwa nkhungu ndi malire pa kukula kwa flange chifukwa cha zovuta za bedi.

3. Resin Transfer Molding (RTM)  

RTM imaphatikizapo kuyika chilimbikitso cha fiberglass mu nkhungu yotsekedwa, kubaya utomoni kuti ulowetse ulusi, ndikuchiritsa. Njirayi ikuphatikizapo:

• Kuyika preform ya fiberglass yofananira ndi geometry ya flange mu nkhungu.
• Kulowetsa utomoni wocheperako ndikuwongolera kutentha ndi kukakamizidwa kuti kukhutitse preform ndikuchotsa mpweya.
• Kutentha kuchiritsa ndi kugwetsa flange yomalizidwa.

Ma resins nthawi zambiri amakhala poliyesitala wopanda unsaturated kapena epoxy, pomwe zolimbikitsira zimaphatikizapoma fiberglass mosalekeza mphasakapena nsalu zoluka. Zodzaza ngati calcium carbonate, mica, kapena aluminiyamu hydroxide zitha kuwonjezeredwa kukulitsa katundu kapena kuchepetsa mtengo.

Ubwino: Malo osalala, zokolola zambiri, kugwira ntchito kwa nkhungu zotsekedwa (kuchepetsa mpweya woipa ndi zoopsa za thanzi), kuyanjanitsa kwa ulusi wolunjika kuti mukhale ndi mphamvu zowonjezera, ndalama zotsika mtengo, komanso kuchepetsa kugwiritsa ntchito zinthu / mphamvu.

4. Vuto-Assisted Resin Transfer Molding (VARTM)

VARTM imasintha RTM pobaya utomoni pansi pa vacuum. Ntchitoyi imaphatikizapo kusindikiza chithunzithunzi cha fiberglass pa nkhungu yamphongo ndi thumba la vacuum, kutulutsa mpweya mu nkhungu, ndi kujambula utomoni mu preform pogwiritsa ntchito vacuum pressure.

Poyerekeza ndi RTM, VARTM imapanga ma flanges okhala ndi porosity yotsika, fiber yambiri, ndi mphamvu zapamwamba zamakina.

5. Airbag-anathandiza utomoni kutengerapo akamaumba

Airbag yothandizidwa ndi RTM ndi mtundu waukadaulo wopangira womwe umapangidwa pamaziko a RTM. Njira yokonzekera ma flanges ndi njira iyi yopangira ili motere: galasi lopangidwa ndi galasi lopangidwa ndi galasi lopangidwa ndi flange limayikidwa pamwamba pa thumba la airbag, lomwe limadzazidwa ndi mpweya, kenako limatuluka kunja ndipo limakhala ndi danga la nkhungu ya cathode, ndi preform ya flange pakati pa nkhungu ya cathode ndi thumba la airbag ndi lopangidwa ndi kuchiritsidwa.

Ubwino: Kukula kwa thumba la airbag kungapangitse kuti utomoni upite ku gawo la preform lomwe silinalowetsedwe, kuonetsetsa kuti preform imayikidwa bwino ndi utomoni; utomoni zili akhoza kusinthidwa ndi kuthamanga kwa airbag; Kupanikizika kwa airbag kumagwiritsidwa ntchito mkati mwa flange, ndipo flange pambuyo pochiritsa imakhala ndi porosity yochepa komanso makina abwino. Nthawi zambiri, mutatha kukonzekeraMtengo wa FRPflange ndi njira yopangira pamwambayi, kunja kwa flange iyeneranso kukonzedwa molingana ndi zofunikira zogwiritsira ntchito kutembenuza ndi kubowola m'mabowo ozungulira kuzungulira kwa flange.
