Cov ntaub ntawv carbon fiber ntau yog siv dav hauv aerospace, tsheb tsim, tsheb thauj mus los thiab lwm yam kev lag luam vim lawv cov khoom siv zoo heev thiab tshuaj lom neeg. Txawm li cas los xij, nws lub zog hloov pauv ntawm qhov kub thiab txias yog ib qho tseem ceeb uas txiav txim siab nws daim ntawv thov ntau yam. Kab lus no yuav tshawb txog lub zog hloov pauv ntawm cov pa roj carbon fiber ntau ntawm qhov kub thiab txias.
Lub siab kub tsis kam ntawm carbon fiber nws tus kheej
Cov pa roj carbon fiber nws tus kheej muaj qhov kub thiab txias tsis kam. Raws li kev xav, carbon fiber tuaj yeem tiv taus qhov kub siab txog 2600 degree. Txawm li cas los xij, carbon fiber feem ntau tsis siv ib leeg, tab sis muaj cov khoom siv xws li cob los tsim cov khoom tiav. Lub zog hloov ntawm qhov sib xyaw no ntawm qhov kub thiab txias tuaj yeem cuam tshuam los ntawm hom resin siv.

Epoxy cob composite
Epoxy resin yog ib qho ntawm cov khoom siv feem ntau siv hauv cov pa roj carbon fiber ntau. Txawm li cas los xij, epoxy resin muaj qhov kub tsis zoo thiab feem ntau oxidizes thiab decomposes ntawm 180 ~ 200 degree. Yog li ntawd, lub zog ntawm epoxy-based carbon fiber composites yuav txo qis ntawm qhov kub thiab txias.
thermoplastic cob composite
Piv rau epoxy resins, thermoplastic resins (xws li polyphenylene sulfide thiab polyether ether ketone) muaj qhov kub zoo dua. Cov pa roj carbon fiber ntau ua los ntawm cov khoom siv no qhia tias tsis muaj zog ntawm qhov kub thiab txias.
ceramic matrix sib xyaw
Ntawm tag nrho cov hom ntawm carbon fiber composites, ceramic matrix composites muaj zog tiv thaiv rau siab kub. Cov khoom siv no tuaj yeem nyob ruaj khov ntawm qhov kub txog li 1500 degree, thiab nws lub zog tsis tshua muaj kev hloov pauv ntawm qhov kub thiab txias.
nyob rau hauv xaus
Lub zog ntawm carbon fiber composites ntawm kub kub hloov feem ntau nyob ntawm seb hom resin siv. Lub zog ntawm epoxy resin-based composites txo qis ntawm qhov kub thiab txias, thaum cov thermoplastic resin thiab ceramic-based composites tau zoo dua qhov kub thiab txias. Kev nkag siab txog cov khoom no yog qhov tseem ceeb rau kev xaiv cov pa roj carbon fiber ntau uas tsim nyog rau ib daim ntawv thov tshwj xeeb.
