Kodi chopped carbon fiber ndi chiyani?

Mpweya wa carbon wodulidwa ndi carbon fiber yomwe imadulidwa mwachidule. Apa kaboni CHIKWANGWANI ndi chabe morphological kusintha, kuchokera mpweya CHIKWANGWANI filament mu filament lalifupi, koma ntchito yachidule mpweya CHIKWANGWANI palokha sanasinthe. Ndiye n'chifukwa chiyani mukufuna kudula filament yabwino mwachidule?
Choyamba, tiyenera kuyamba kuumba ndondomeko ya zinthu kompositi. Nthawi zambiri mpweya CHIKWANGWANI filament kuti alukidwe mu mpweya CHIKWANGWANI nsalu kapena kukhala mpweya CHIKWANGWANI prepreg, ndiyeno kupyolera mukuumba, RTM, vacuum bagging, zitini otentha atolankhani ndi njira zinamu mitundu yosiyanasiyana ya carbon fiber composite. Kumene, palinso njira akamaumba kuti safuna zipangizo wapakatikati, mwachindunji kudzera mpweya CHIKWANGWANI filament kwa akamaumba, monga pultrusion akamaumba, mapiringidzo akamaumba ndi zina zotero.
Mpweya wa mpweya wolukidwa mu nsalu za kaboni CHIKWANGWANI kapena kupangidwa prepreg, kupita kupanga zinthu, pali kuipa kwachilengedwe, sikwabwino kumata nkhungu. Kukhalapo kwa nkhungu ndiko kupereka mawonekedwe kwa zinthu zophatikizika, nkhungu imakhala ndi mawonekedwe otani, chinthu chomaliza chophatikizika chimakhalanso ndi mawonekedwe otani. Komabe, ngati nsalu ya kaboni fiber kapena prepreg sichikukwanira bwino nkhungu, mawonekedwe azinthu zophatikizika sizikugwirizana ndi mawonekedwe a nkhungu. Kuphatikiza apo, m'makona ena, nsalu ya kaboni fiber imakhala yosavuta kulumikiza, kupanga malo am'deralo, omwe pamapeto pake amayambitsa kuchepa kwa magwiridwe antchito a carbon fiber composite.
Mpweya wa carbon fiber mkati mwa nsalu ya carbon fiber kapena prepreg ndi womangidwa ndipo si wophweka kusuntha. Makamaka pankhani ya kukakamizidwa, utomoni ndi carbon fiber filament kuyenda ndi koyipa kwambiri, zomwe pamapeto pake zimabweretsa zovuta kuumba kapena kuwonongeka kwa magwiridwe antchito.
The wamfupi kutalika, bwino fluidity wacarbon fiber wodulidwa. Ziyenera kudziwika kuti jekeseni akamaumba ndi ambiri ankagwiritsa ntchito ndi okhwima luso mu ndondomeko akamaumba pulasitiki. Ngati atagwiritsidwa ntchito popanga zinthu zophatikizika, kudzakhala kusintha kwakukulu.
Komabe, kutalika kwa kaboni wamtundu waufupi sungathe kuchepetsedwa, chifukwa kufupikitsa kutalika kwa kaboni wamtundu waufupi, utomoni ndi carbon fiber kugwirizana zidzakhala zofooka. Chifukwa mgwirizano pakati pa utomoni ndi mpweya wa carbon umagwirizana mwachindunji ndi malo okhudzana ndi pakati pawo, ngati kutalika kwafupikitsidwa, ndiye kuti malo okhudzidwawo achepetsedwa.
Ndiye pali kutsutsana apa, ndiko kuti, kutsutsana pakati pa machitidwe a fiber-cut-cut fiber ndi kuyenda. Utali wa ulusi, umakhala wocheperako kuti umwazikane, ulusi ndi ulusi ndizosavuta kulumikiza, koma kulimba kwa ulusi ndi utomoni kuphatikizika, kuchokera kuzinthu zophatikizika kumakhala kokwezeka. Kufupikitsa kwa ulusi wa utomoni, ndikosavuta kufalikira, ndikuyenda bwino, koma mgwirizano wa utomoni ndi utomoni ndi wofooka pang'ono. Momwe mungasinthire zotsutsanazi, ziyenera kuphunziridwa, nthawi zambiri, kuti muchepetse mpweya wowonjezera wa kaboni wolimbitsa ma pellets apulasitiki, kutalika kwa 1-9mm osiyanasiyana.
Palinso njira yopititsira patsogolo mphamvu yolumikizirana pakati pa kaboni fiber ndi utomoni, womwe ndi wothandizila. Kawirikawiri, pali sizing wothandizira pamwamba pacarbon fiberfakitale, yomwe imagwiritsidwa ntchito kuteteza kaboni CHIKWANGWANI kuti linting mu ndondomeko kulongedza katundu, kusamutsa ndi ntchito, ndipo Komano, ntchito kuphatikiza mpweya CHIKWANGWANI ndi utomoni, ndi kuchita mbali ya utithandize kugwirizana mphamvu.
Komabe, izi sizing wothandizila kwenikweni ndi thermosetting resin. Ma resins ambiri omwe amagwiritsidwa ntchito popanga ma pellets ndi ma resins a thermoplastic, kotero kuti saizi iyenera kusinthidwa. Imodzi ndikuwotcha choyambira choyambirira ndikupanga chosanjikiza chatsopano. Imodzi ndikuwotcha choyambira choyambirira ndikupanga chosanjikiza chatsopano; ina ndi yopangira saizi kachiwiri pamaziko a choyambirira saizi, chomwe chimatchedwa secondary sizing.
Kuphatikiza pa kupanga ma granules opangira jakisoni,carbon fiber wodulidwaali ndi ntchito zina, monga zopangidwa ndi carbon fiber mat, kapena zopangidwa ndi pepala la carbon fiber. Utali wofunikira wa ulusi wodulidwa wa kaboni udzakhala wautali kuposa kutalika kwa ulusi wodulidwa wa granules.
Kuonjezera apo, kuwonjezera pa ulusi wa carbon wodulidwa mwachisawawa, palinso nsonga za carbon fibers. Chingwe chodulachi chili mu njira yachidule isanachitike chikoka cha kaboni chamtundu wina wodziwikiratu, ndiye kuti ulusi wodulidwa wafupika uli ndi mawonekedwe a mtolo, wokhala ndi kuchuluka kwa utomoni udzakhala wochuluka kuposa ulusi wina wamfupi.
