Cov ntaub ntawv carbon/carbon sib xyaw tau dhau los ua ib tiam tshiab ntawm cov ntaub ntawv nres los hloov cov ntaub ntawv sib xyaw ua los ntawm hlau vim lawv cov yam ntxwv tshwj xeeb ntawm kev siv tshuab, kev ua kom sov thiab kev sib txhuam thiab kev hnav.
Nws cov yam ntxwv tseem ceeb yog raws li nram no:
(1) Qhov ceev ntawm cov khoom siv yog qis li 1.5g / cm3, uas tuaj yeem txo qhov hnyav ntawm cov qauv ntawm lub disc nres;
(2) Cov khoom siv muaj kev tiv thaiv zoo heev thiab lub disc nres muaj lub neej ntev, uas yog ntau dua ob npaug ntawm cov khoom siv hlau matrix composite;
(3) Qhov ruaj khov dynamic friction factor, zoo heev anti-sticking thiab anti-adhesion zog;
(4) Ua kom yooj yim rau kev tsim cov disc nres thiab tsis tas yuav muaj cov ntaub sib txhuam ntxiv, cov khoom sib txuas, cov pob txha nres, thiab lwm yam;
(5) Cov coefficient me me ntawm kev nthuav dav thermal, muaj peev xwm ua kom sov tshwj xeeb (ob npaug ntawm hlau), thiab kev ua kom sov tau zoo;
(6) Cov pa roj carbon / carbon nres disc muaj qhov kub ua haujlwm siab thiab tiv taus cua sov txog li 2700 ℃.
