Yaya yawan zafin jiki na carbon fiber zai iya jurewa, me yasa yawancin samfuran fiber carbon ba sa jure yanayin zafi

Yadda babban zafin jiki na carbon fiber zai iya jurewa
Carbon fiber kanta yana da tsayin daka na zafin jiki, kuma ana iya cewa abu ne mai tsananin zafin jiki, amma kayan haɗin fiber carbon fiber sun dogara da kayan matrix.
Yan F mazugi yana hako albarkatun mai daga man fetur da kwal.Da farko, ana fitar da polyacrylonitrile, sannan kuma ana fitar da fiber carbon ta hanyar polyacrylonitrile.Abubuwan da ake buƙata na fasaha a nan suna da girma sosai, kuma hadawan abu da iskar shaka, carbonization da graphitization a cikin dukan tsari ne duk Yana buƙatar babban zafin jiki don kammalawa, musamman ma a ƙarƙashin yawan zafin jiki na dubban digiri na dutse quarrying, bayan cire mujallar, da carbon fiber tow. An samu, don haka carbon fiber kanta yana da musamman high zafin jiki juriya, iya jure high zafin jiki na 3000 ℃, kuma zai iya kula da mai kyau yi fa'ida.
Me yasa yawancin samfuran fiber carbon ba sa jure yanayin zafi?
Kamar yadda aka ambata a sama, carbon fiber yana da kyau da kuma high zafin jiki juriya.A cikin samar da samfuran fiber carbon, ba abu ne kawai na fiber carbon ba.Ana kuma buƙatar kayan matrix don kammala samar da samfuran fiber marigayi.Kayayyakin fiber carbon suna da juriya ga yanayin zafi.Yi la'akari da babban juriya na zafin jiki na kayan tushe.
Gaskiyar cewa yawancin samfuran fiber carbon ba sa murƙushewa kuma suna zafi sama shine saboda carbon fiber composite kayan sune galibin carbon fiber + kayan haɗaɗɗun guduro, kuma abun ciki na filayen fiber na ƙarshen a cikin kayan haɗin yana kusan 40% -45%, don haka samarwa Babban juriya na zafin jiki na ƙãre carbon fiber kayayyakin yana da alaka da babban zafin jiki juriya na guduro.Wannan kamar ka'idar ganga katako ne.Matsakaicin juriya na zafin jiki na guduro ya zama babban iyakar juriya mai zafi na samfuran fiber carbon.
A karkashin yanayi na al'ada, babban juriya na resin matrix yana kusan 180C.Idan ya wuce wannan zafin jiki na dogon lokaci, zai sa matrix resin ya narke, wanda zai shafi aikin ƙarshe na samfurin.
Bugu da ƙari, don ƙara haɓaka ƙarfin juriya na zafin jiki, tushen yatsan itacen zai zaɓi matrix tare da babban juriya na zafin jiki, wato, filastik na musamman.Idan kuna da kayan matrix tare da fa'idodin aiki mafi girma kamar PEK da PPS, to samfuran fiber carbon da aka samar za su yi tsayayya da zafin jiki na iya kaiwa sama da 20YC.Idan ana buƙatar juriya mafi girma na zafin jiki, ya kamata a zaɓi tushen carbon ko matrix ƙarfe na yumbu.Irin wannan juriya mai zafi na iya zama mafi kyau.
