Ingakanani izinga lokushisa eliphezulu elingamelana ne-carbon fibre, kungani imikhiqizo eminingi ye-carbon fiber ingamelani nezinga lokushisa eliphezulu

Izinga lokushisa eliphezulu lingakwazi ukumelana ne-carbon fiber
I-Carbon fiber ngokwayo inokumelana nezinga lokushisa eliphezulu kakhulu, futhi kungathiwa iyimpahla ekwazi ukumelana nokushisa okuphezulu kakhulu, kodwa izinto ezihlanganisiwe ze-carbon fibre zincike ezintweni ze-matrix.
I-Yan F cone ikhipha izinto zokusetshenziswa ku-petroleum namalahle.Okokuqala, i-polyacrylonitrile ikhishwa, bese i-carbon fiber ikhishwa nge-polyacrylonitrile.Izidingo zobuchwepheshe lapha ziphezulu kakhulu, futhi i-oxidation, i-carbonization kanye ne-graphitization kuyo yonke inqubo idinga izinga lokushisa eliphezulu ukuze liqedele, ikakhulukazi ngaphansi kwezinga lokushisa eliphakeme lama-degree ayizinkulungwane ezimbalwa zokumba amatshe, ngemva kokukhipha umagazini, i-carbon fiber tow. iyatholakala, ngakho-ke i-carbon fiber ngokwayo inokumelana nokushisa okuphezulu kakhulu, ingamelana nezinga lokushisa eliphakeme lika-3000 ℃, futhi ingagcina inzuzo yokusebenza okuhle.
Kungani imikhiqizo eminingi ye-carbon fiber ingamelani nezinga lokushisa eliphezulu?
Njengoba kushiwo ngenhla, i-carbon fiber inokumelana okuhle nokushisa okuphezulu.Ekukhiqizeni imikhiqizo ye-carbon fiber, akuyona nje into ye-carbon fiber.Impahla ye-matrix nayo iyadingeka ukuze kuqedelwe ukukhiqizwa kwemikhiqizo yefiber ephuzile.Imikhiqizo ye-carbon fiber imelana nokushisa okuphezulu.Cabanga ukumelana nokushisa okuphezulu kwezinto eziyisisekelo.
Iqiniso lokuthi imikhiqizo eminingi ye-carbon fiber ayishwabani futhi iyashisisa kungenxa yokuthi izinto ezihlanganisiwe ze-carbon fibre ziyizinto eziyinhlanganisela ezisekelwe ku-carbon fiber + ne-resin-based composite, futhi okuqukethwe kwe-fiber tow sekwephuzile ezintweni eziyinhlanganisela cishe ku-40% -45%, ngakho-ke. ukukhiqizwa Ukumelana nokushisa okuphezulu kwemikhiqizo ye-carbon fiber eqediwe kuhlobene nokumelana nokushisa okuphezulu kwe-resin.Lokhu kufana nesimiso semiphongolo yokhuni.Umkhawulo wokumelana nokushisa okuphezulu kwe-resin usuphenduke umkhawulo ophezulu wokumelana nokushisa okuphezulu kwemikhiqizo ye-carbon fiber.
Ngaphansi kwezimo ezijwayelekile, ukumelana nokushisa okuphezulu kwe-resin matrix cishe ku-180C.Uma idlula lelizinga lokushisa isikhathi eside, lizokwenza ukuthi i-resin matrix incibilike, okuzothinta ukusebenza kokugcina komkhiqizo.
Ngaphezu kwalokho, ukuze kuthuthukiswe ukumelana nokushisa okuphezulu, isisekelo somunwe wesihlahla sizokhetha i-matrix enokumelana nokushisa okuphezulu, okungukuthi, ipulasitiki ekhethekile.Uma unempahla ye-matrix enezinzuzo zokusebenza okuphezulu njenge-PEK ne-PPS, khona-ke imikhiqizo ye-carbon fiber ekhiqizwayo izomelana nezinga lokushisa lingafinyelela ngaphezu kuka-20YC.Uma kudingeka ukumelana nokushisa okuphezulu, i-carbon-based noma i-ceramic metal matrix kufanele ikhethwe.Ukumelana nokushisa okunjalo okuphezulu kungaba ngcono.
