Cov teb thov ntawm cov pa roj carbon / Carbon Composites

Cov khoom sib xyaw ua los ntawm cov pa roj carbon / carbon yog cov khoom sib xyaw ua los ntawm cov pa roj carbon uas muaj zog nrogcov roj carbon fiber or cov fiber graphite. Lawv cov qauv carbon tag nrho tsis yog tsuas yog khaws cov khoom siv zoo heev thiab kev tsim qauv yooj yim ntawm cov khoom siv fiber reinforced, tab sis kuj muaj ntau qhov zoo ntawm cov khoom siv carbon, xws li qhov ceev tsawg, coefficient nthuav dav thermal qis, conductivity thermal siab, tiv taus cua sov zoo heev, tiv taus ablation thiab tiv taus kev sib txhuam, Nws yog qhov tseem ceeb tshwj xeeb uas cov khoom siv kho tshuab ntawm cov khoom siv nce nrog qhov nce ntawm qhov kub, uas ua rau nws yog cov khoom siv zoo tagnrho hauv aerospace, automotive, kev kho mob thiab lwm yam teb.

Cov khoom sib xyaw ua los ntawm cov pa roj carbon / carbon yog siv dav hauv cov ntaub ntawv tiv thaiv cua sov hauv aerospace thiab cov khoom siv thermal ntawm lub dav hlau. Tus neeg sawv cev zoo tshaj plaws ntawm kev lag luam carbon / carbon composites yog lub dav hlau nres disc ua los ntawm cov pa roj carbon /cov khoom sib xyaw ua los ntawm cov pa roj carbon.

Hauv thaj chaw pej xeem, cov pa roj carbon / carbon composites yog cov laus dua, uas yog siv los ua cov ntaub ntawv thermal teb raumonocrystalline silicon cub tawg, polycrystalline silicon ingot cub tawg thiab hydrogenation cub tawg hauv thaj teb ntawmlub zog hnub ci.

Hauv kev kho mob biomedical, cov pa roj carbon / carbon composites muaj cov kev thov dav dav vim lawv zoo sib xwsmodulus elasticthiab biocompatibility nrog pob txha cuav.

Hauv kev lag luam, cov pa roj carbon / carbon composites tuaj yeem siv ua cov khoom siv piston thiab cov pas nrig txuas ntawm lub cav diesel. Qhov kub ntawm cov khoom siv cav diesel carbon / carbon composite tuaj yeem nce ntxiv los ntawm 300 ℃ txog 1100 ℃. Tib lub sijhawm, nws qhov ceev yog qis, txo qhov poob ntawm lub zog, thiab kev ua haujlwm ntawm lub cav cua sov tuaj yeem ncav cuag 48%; Vim yog qhov coefficient qis ntawm thermal expansion ntawm C / C composites,lub nplhaib kaws thiab lwm yam ntaub ntawv siv tsis tau rau hauv qhov kub thiab txias zoo, uas ua rau cov qauv ntawm cov khoom yooj yim dua.
