Cov Khoom Siv C/C Composite lossis Carbon-Carbon Composite

Cov Khoom Siv Carbon Composites:
Cov khoom sib xyaw ua los ntawm cov pa roj carbon (Carbon-fiber-reinforced carbon composites) (CFC) yog ib hom khoom siv uas tsim los ntawm cov pa roj carbon fiber ntau thiab cov pa roj carbon matrix tom qab kev ua kom zoo dua ntawm graphitization.

Nws tuaj yeem siv dav hauv qhov chaw kub siab ntawm ntau yam qauv, cua sov thiab lub nkoj. Piv nrog rau cov ntaub ntawv engineering ib txwm muaj, carbon carbon composite muaj cov txiaj ntsig zoo li nram no:

1) Lub zog siab

2) Kub siab txog li 2000 ℃

3) Kev tiv thaiv thermal poob siab

4) Cov coefficient qis ntawm kev nthuav dav thermal

5) Muaj peev xwm ua kom sov me me

6) Kev tiv thaiv corrosion zoo heev thiab kev tiv thaiv hluav taws xob

Daim Ntawv Thov:
1. Siv rau hauv kev tsim dav hlau. Vim yog cov khoom sib xyaw ua ke, nws muaj kev ruaj khov zoo, muaj zog tshwj xeeb thiab tawv. Nws tuaj yeem siv rau kev tsim cov nres dav hlau, tis thiab lub fuselage, lub kav hlau txais xov tooj cua thiab cov qauv txhawb nqa, tis thiab lub plhaub hnub ci, lub plhaub foob pob hluav taws loj, lub plhaub cav, thiab lwm yam.

2. Kev lag luam tsheb.

3. Thaj chaw kho mob.

4. Kev rwb thaiv cua sov

5. Chav Ua Kub

6. Kev rwb thaiv tshav ntuj
