Carbon Fiber Composites: Chitsogozo Chokonzekera
Kupanga zida za carbon fiber (CF) ndi bizinesi yovuta, poganizira mainjiniya ambiri omwe amaganiza zopanga kapena kupanga amachokera ku maziko opangira zida zachitsulo.amatchedwa aluminiyamu wakuda, ndipo mapangidwe ake ndi kupanga kwake akutchedwa luso lakuda.Ndi chiyani kwenikweni?
Cholinga cha kalozera kamangidwe kameneka ndikupereka zidziwitso zonse ndi mafotokozedwe a zinthu zophatikizika ndi kaboni fiber komanso malangizo ena opangira zinthu zopepuka zowoneka bwino kwambiri zokhala ndi kaboni fiber kompositi.
Chifukwa chiyani Carbon Fiber
Zophatikizika za carbon fiber zimakhala ndi makina apadera kwambiri poyerekeza ndi zitsulo ndi mapulasitiki ofanana.Zinthu zake ndi zamphamvu, zolimba, komanso zopepuka.Zophatikizirazi ndizomwe zimasankhidwa pamagwiritsidwe omwe ntchito zopepuka & zapamwamba ndizofunikira kwambiri, monga zida zapamlengalenga, ndege zankhondo, ndi magalimoto othamanga.
Kodi Carbon Fiber Composites ndi chiyani
Zida zophatikizika zimapangidwa pophatikiza kulimbikitsa (fiber) ndi matrix (resin), ndipo kuphatikiza kwa utomoni ndi matrix kumapereka mawonekedwe apamwamba kuposa chilichonse mwazinthu zokha.Muzinthu zophatikizika, ulusi umanyamula katundu wambiri ndipo ndiwothandiza kwambiri pazinthu zakuthupi.Utoto umathandizira kusamutsa katundu pakati pa ulusi, umalepheretsa ulusi kuti usamangirire, ndikumangirira zidazo.
Ndi ndalama zingati?
M'mbuyomu, zopangira kaboni fiber zakhala zokwera mtengo kwambiri, zomwe zachepetsa kugwiritsidwa ntchito kwake kuzinthu zapadera zokha.Komabe, pazaka khumi ndi zisanu ndi ziwiri zapitazi, momwe kugwiritsidwira ntchito kwachulukira komanso makina opangira zinthu zawonjezeka, mtengo wa carbon fiber composites watsika.Kuphatikizikako kwatsitsa mtengo wonse wazinthu zapamwamba za aluminiyamu.Masiku ano, ma composites a carbon fiber ndi othandiza pazachuma pazinthu zambiri monga zamasewera, mabwato ochita masewera olimbitsa thupi, magalimoto ochita bwino, komanso makina apamwamba kwambiri amakampani.
Mapulogalamu
Zopangidwa ndi kompositi ndizosiyanasiyana kwambiri.Mainjiniya amatha kusankha kuchokera kumitundu yosiyanasiyana ya ulusi ndi utomoni kuti apeze zomwe akufuna.Komanso makulidwe azinthu ndi mawonekedwe a fiber amatha kukonzedwa pakugwiritsa ntchito kulikonse.
Ubwino wa carbon fiber composites ndi:
1.Kuuma kwakukulu kwapadera (kuuma kugawanika ndi kachulukidwe)
2. Mphamvu yeniyeni yeniyeni (mphamvu yogawidwa ndi kachulukidwe)
3.Kutsika kwambiri kwa mphamvu yowonjezera kutentha (CTE)
4. X-ray transparent (chifukwa cha kuchepa kwake kwa maselo)
Kodi ma composites a carbon fiber amagwiritsidwa ntchito bwanji?
Kuyika kwapadera kwa ma carbon fiber composites okhala ndi mphamvu zenizeni zenizeni, kuuma, ndi kutsika kwa CTE kumawapatsa malo apadera m'malo ambiri ogwiritsira ntchito monga momwe tawonetsera patebulo ili pansipa:
Zomwe zimagwiritsidwa ntchito pazophatikizira za carbon fiber
Zambiri Zopanga
Ma composites a Carbon Fiber amatengedwa ngati "zinthu zopanga" chifukwa magawowa amatha kupangidwa kuti akhale ndi mphamvu kapena kuuma komwe kuli kofunikira.Izi zimatheka poyika zida mwanzeru ndikuwongolera ulusi kuti zigwirizane ndi zofunikira.Komanso, mapangidwe ndi kusinthasintha kopanga komwe ma kaboni fiber composites amapereka kumapereka mwayi wokhathamiritsa mapangidwe, monga kuphatikiza ndi kuphatikiza zinthu zambiri mu-situ, kuti muchepetse mtengo wathunthu.
Zida
Nkhungu zimagwiritsidwa ntchito kufotokoza mawonekedwe a zigawo zamagulu.Gawo lophatikizika lidzatenga mawonekedwe onse ndi mawonekedwe a nkhungu;choncho ubwino wa gawolo umakhudzidwa kwambiri ndi ubwino wa nkhungu.Amatha kukhala amuna kapena akazi.Nkhungu zazikazi ndizofala kwambiri ndipo zidzatulutsa gawo lokhala ndi kunja kosalala pamene nkhungu yamphongo idzatulutsa mkati mwa mkati.Chikombole chofananira (chachimuna ndi chachikazi) chimafunika ngati gawolo likuphatikizidwa pogwiritsa ntchito makina osindikizira.
Zida ziwiri, zomwe zimatchedwa "clamshell"
Zoumba zimatha kupangidwa ndi zida zophatikizika, epoxy yodzaza ndi chitsulo kapena yopangidwa ndi aluminiyamu kapena chitsulo.Mtundu wa nkhungu ndi zipangizo zomwe zimagwiritsidwa ntchito zimadalira mtundu wa gawo ndi kuchuluka kwa kupanga.
Njira Yopangira
Kupanga kwapamwamba kwa mpweya wa kaboni nthawi zambiri kumachitika pogwiritsa ntchito utomoni wa kaboni wopangidwa kale ndi thermoset resins.Njira ziwiri zazikuluzikulu zomwe zimagwiritsidwa ntchito ndi:
1. Kuyika manja
Kuyika kwa manja kwa zida zolukidwa asanalowe m'thupi akadali gawo lalikulu lamakampani opanga zinthu zambiri, zomwe zimafunikira luso ndi chidziwitso cha anthu ogwira ntchito kuti apange ma plies osalala kukhala mawonekedwe ovuta.Imatha kupanga magwiridwe antchito apamwamba komanso magawo ovuta koma imatha kukhala yokwera mtengo komanso yosinthika kwambiri.
2. Automated Fiber Placement (AFP)
Zinthu zazikulu zomwe muyenera kuziganizira ndikukula kwa ulusi womwe mukugwiritsa ntchito komanso utali wa compaction roller.
