Cov khoom sib xyaw ua los ntawm cov pa roj carbon / carbon(txij no mus hu ua "C / C lossis CFC) yog ib hom khoom sib xyaw ua ke uas yog ua los ntawm carbon thiab txhawb nqa los ntawm carbon fiber thiab nws cov khoom (carbon fiber preform). Nws muaj ob qho tib si inertia ntawm carbon thiab lub zog siab ntawm carbon fiber. Nws muaj cov khoom siv kho tshuab zoo, tiv taus cua sov, tiv taus corrosion, txhuam damping thiab thermal thiab hluav taws xob conductivity yam ntxwv.
CVD-SiCtxheej muaj cov yam ntxwv ntawm cov qauv sib xws, cov khoom siv compact, kub tsis kam, oxidation tsis kam, siab purity, acid & alkali tsis kam thiab organic reagent, nrog cov khoom ruaj khov thiab tshuaj lom neeg.
Cov yam ntxwv tseem ceeb:
1. Kev tiv thaiv oxidation kub siab:qhov kev tiv thaiv oxidation tseem zoo heev thaum qhov kub siab txog 1600 C.
2. Kev huv siab: ua los ntawm cov tshuaj lom neeg ua pa hauv qab qhov kub siab chlorination.
3. Kev tiv thaiv kev yaig: kev nyuaj siab, qhov chaw me me, cov khoom me me.
4. Kev tiv thaiv corrosion: acid, alkali, ntsev thiab cov organic reagents.
