Kutentha kochuluka bwanji kungathe kupirira kaboni fiber, chifukwa chiyani zinthu zambiri za carbon fiber sizimalimbana ndi kutentha kwakukulu

Momwe kutentha kwa kaboni kungapirire
Mpweya wa carbon womwewo uli ndi kutentha kwambiri, ndipo ukhoza kunenedwa kuti ndi chinthu chopanda kutentha kwambiri, koma zipangizo za carbon fiber zimadalira matrix.
Yan F cone amachotsa zopangira kuchokera ku petroleum ndi malasha.Choyamba, polyacrylonitrile imachotsedwa, ndiyeno mpweya wa carbon umachokera ku polyacrylonitrile.The luso zofunika pano ndi apamwamba kwambiri, ndi makutidwe ndi okosijeni, carbonization ndi graphitization mu ndondomeko yonse ndi zonse Zimafunika kutentha mkulu kuti amalize, makamaka pansi pa kutentha kwa madigiri zikwi zingapo za miyala miyala, pambuyo kuchotsa magazini, ndi mpweya CHIKWANGWANI tow. ndi analandira, kotero mpweya CHIKWANGWANI palokha ali kwambiri kutentha kukana, akhoza kupirira kutentha kwa 3000 ℃, ndipo akhoza kukhala wabwino ntchito mwayi.
Chifukwa chiyani zinthu zambiri za carbon fiber sizimalimbana ndi kutentha kwambiri?
Monga tanena kale, kaboni fiber imakhala yabwino komanso kutentha kwambiri.Popanga zinthu za carbon fiber, sizinthu za carbon fiber.Chida cha matrix chimafunikanso kuti amalize kupanga zinthu zochedwa fiber.Zopangira kaboni fiber zimalimbana ndi kutentha kwambiri.Ganizirani za kutentha kwakukulu kwa zinthu zoyambira.
Mfundo yakuti zinthu zambiri za carbon fiber sizimakwinya ndi kutentha ndi chifukwa chakuti zida za carbon CHIKWANGWANI zimakhala ndi zinthu zambiri za carbon fiber + resin-based composite materials, ndipo zomwe zili kumapeto kwa fiber muzinthu zophatikizika zimakhala pafupifupi 40% -45%, kotero. kupanga Kukana kwa kutentha kwakukulu kwa zinthu zomalizidwa za carbon fiber kumagwirizana ndi kukana kwa kutentha kwa utomoni.Izi zili ngati mfundo ya migolo yamatabwa.Kuchuluka kwa kutentha kwa resin kwakhala malire apamwamba a kutentha kwambiri kwa zinthu za carbon fiber.
Nthawi zonse, kukana kutentha kwa matrix a resin ndi pafupifupi 180C.Ngati kupitirira kutentha kumeneku kwa nthawi yaitali, kumapangitsa kuti matrix a resin asungunuke, zomwe zidzakhudza ntchito yomaliza ya mankhwala.
Kuonjezera apo, pofuna kupititsa patsogolo kutentha kwa kutentha, mtengo wa chala udzasankha matrix omwe ali ndi kutentha kwapamwamba kwambiri, ndiko kuti, pulasitiki yapadera.Ngati muli ndi matrix okhala ndi maubwino apamwamba kwambiri monga PEK ndi PPS, ndiye kuti zinthu zomwe zimapangidwa ndi kaboni fiber sizingagwirizane ndi Kutentha kumatha kufika pamwamba pa 20YC.Ngati kutentha kwapamwamba kumafunika, matrix opangidwa ndi kaboni kapena ceramic metal ayenera kusankhidwa.Kukana kutentha koteroko kungakhale bwinoko.
