Cov pa roj carbon / carbon composites(tom qab no hu ua "C / C lossis CFC") yog ib hom khoom sib xyaw uas yog raws li cov pa roj 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 siab zog ntawm carbon fiber. Nws muaj cov khoom siv zoo, ua haujlwm kub, tiv thaiv corrosion, kev sib txhuam damping thiab thermal thiab hluav taws xob conductivity yam ntxwv
CVD-SiCtxheej txheej muaj cov yam ntxwv ntawm cov qauv zoo, cov khoom siv compact, kub tsis kam, oxidation tsis kam, siab purity, acid & alkali tsis kam thiab organic reagent, nrog lub cev ruaj khov thiab tshuaj lom neeg.
Cov yam ntxwv tseem ceeb:
1. Kub oxidation kuj:oxidation kuj tseem zoo heev thaum kub siab li 1600 C.
2. High purity: ua los ntawm cov tshuaj vapor deposition nyob rau hauv siab kub chlorination mob.
3. Erosion kuj: siab hardness, compact nto, zoo hais.
4. Corrosion kuj: acid, alkali, ntsev thiab organic reagents.
