Cov pa roj carbon fiber ntau yog ib hom tshwj xeeb ntawm fiber ntau uas muaj cov ntsiab lus carbon; nws cov ntsiab lus carbon txawv nyob ntawm seb hom tshwj xeeb, feem ntau tshaj 90%. Cov pa roj carbon fiber muaj cov yam ntxwv ntawm cov pa roj carbon monoxide-raws li cov ntaub ntawv- xws li siab- kub tsis kam, tsis kam tiv taus, hluav taws xob conductivity, thermal conductivity, thiab corrosion kuj. Txawm li cas los xij, tsis zoo li cov ntaub ntawv carbon zoo tib yam, nws nthuav tawm cov anisotropy hauv nws daim ntawv lub cev; Nws yog hloov tau, tuaj yeem ua tiav rau hauv ntau cov qauv ntaub, thiab ua kom pom qhov muaj zog tensile tshwj xeeb raws li cov kev taw qhia ntawm fiber ntau. Tsis tas li ntawd, cov pa roj carbon fiber muaj qhov sib nqus tshwj xeeb, uas ua rau muaj lub zog tshwj xeeb zoo heev.
Cov pa roj carbon fiber ntau yog tsim los ntawm cov khoom siv hluavtaws fibers uas muaj cov ntsiab lus carbon siab thiab tsis yaj thaum ua haujlwm thermal. Cov fibers precursor no tau dhau los ua cov txheej txheem tsim khoom, suav nrog thermal stabilization (oxidation), carbonization, thiab graphitization.
Cov pa roj carbon fiber ntau yog cov khoom siv tshiab txawv los ntawm nws cov khoom siv zoo tshaj plaws. Nws lub ntiajteb txawj nqus tshwj xeeb yog tsawg tshaj li ib -quarter ntawm hlau.
Cov pa roj carbon fiber ntau-cov khoom siv polymer (CFRP) feem ntau pom muaj lub zog tensile tshaj 3500 MPa- xya mus rau cuaj npaug ntawm cov hlau- thiab tensile elastic modulus xws li 23,000 txog 43,000 MPa, uas yog siab dua li cov hlau. Yog li ntawd, lub zog tshwj xeeb ntawm CFRP- txhais raws li qhov piv ntawm cov khoom siv lub zog rau nws qhov ntom ntom - tuaj yeem tshaj 2000 MPa / (g / cm³), qhov tshwj xeeb lub zog ntawm A3 steel tsuas yog nyob ib ncig ntawm 59 MPa / (g / cm³); Ib yam li ntawd, nws qhov tshwj xeeb modulus kuj siab dua li cov hlau.
