Carbon fiber yana da ƙayyadaddun ƙayyadaddun ƙarfi, ƙayyadaddun ƙayyadaddun modulus, juriya na gajiya, juriya na lalata da sauran kyawawan kaddarorin, ana amfani da su sosai a sararin samaniya, masana'antar soja, kayan wasanni da sauran fannoni. Carbon fiber ƙarfafa polymerization

Carbon fiber yana da ƙayyadaddun ƙayyadaddun ƙarfi, ƙayyadaddun ƙayyadaddun modulus, juriya na gajiya, juriya na lalata da sauran kyawawan kaddarorin, ana amfani da su sosai a sararin samaniya, masana'antar soja, kayan wasanni da sauran fannoni. Kaddarorin injina na fiber carbon sun ƙarfafa abubuwan haɗin matrix na polymer sun fi mayar da hankali kan kaddarorin mu'amala tsakanin fiber carbon da matrix. Duk da haka, santsin saman fiber carbon fiber, manyan kaddarorin motsin rai da ƴan ƙungiyoyi masu aiki da sinadarai suna haifar da haɗin kai mai rauni tsakanin fiber carbon da guduro matrix, kuma lokaci na mu'amala shine sau da yawa raunin haɗin kayan haɗin gwiwa. Ƙirƙirar microstructure na haɗin fiber carbon yana da alaƙa da alaƙa da abubuwan haɗin kai. Matsakaicin filaye na fiber carbon a ƙarshe ya ta'allaka ne a cikin yanayin yanayin halittar fiber carbon da nau'ikan ƙungiyoyin aikin sinadarai. Dukansu haɓakar ƙungiyoyi masu aiki da haɓakar roughness na fiber fiber surface ne m ga karuwa da carbon fiber surface makamashi. Kaddarorin jiki na fiber carbon galibi sun haɗa da ilimin halittar jiki, girman tsagi da rarrabawa, ƙarancin ƙasa, makamashi kyauta da sauransu. Dangane da ilimin halittar jiki, akwai pores da yawa, tsagi, ƙazanta da lu'ulu'u a saman fiber na carbon, waɗanda ke da babban tasiri akan abubuwan haɗin gwiwa na kayan haɗin gwiwa. The sinadaran reactivity na carbon fiber surface yana da kusanci da tattarawar ƙungiyoyi masu aiki, kuma waɗannan ƙungiyoyin masu aiki sune galibi oxygen ɗauke da ƙungiyoyin aiki kamar ƙungiyar haske, ƙungiyar spindle da ƙungiyar epoxy. Adadin ƙungiyoyi masu aiki akan saman fiber carbon ya dogara ne akan hanyar jiyya ta hanyar electrochemical da matakin ko zazzabi na fiber carbonization. Alal misali, maganin acid zai ba da fiber daban-daban ƙungiyoyi masu aiki fiye da maganin alkali, kuma don yanayin jiyya ɗaya, mafi girma da zafin jiki na carbonization, ƙananan ƙungiyoyi masu aiki. Low modulus carbon fiber gabaɗaya yana da ƙarin ƙungiyoyi masu aiki saboda ƙarancin ƙarancin carbonization, don haka zai amsa tare da rukunin epoxy a cikin shirye-shiryen abubuwan haɗin gwiwar epoxy matrix, yayin da za'a iya watsi da amsawar tsarin fiber carbon fiber mai girma, da fiber da guduro. galibi suna da raunin mu'amala. Yawancin karatu sun nuna cewa za a iya inganta abubuwan haɗin gwiwar haɗin gwiwar da kyau ta hanyar gyaggyara ƙirar ƙirar ƙira ta hanyar gyaran gyare-gyare na fiber carbon, wanda shine ɗayan wuraren bincike a fagen kayan kwalliyar carbon fiber.
