Yuav ua li cas corrosion kuj ua tau zoo ntawm carbon fiber composites?
Thaum nws los txog rau cov khoom siv hlau tsoos, qhov kev txiav txim siab tseem ceeb yog lawv lub neej ua haujlwm. Peb paub tias cov khoom siv hlau muaj cov khoom siv hluav taws xob siab thiab muaj kev cuam tshuam rau corrosion. Nrog kev tshwm sim ntawm cov khoom siv tshiab carbon fiber, nws tsis tsuas yog muaj qhov zoo xws li lub teeb yuag thiab lub zog siab, tab sis kuj nthuav tawm cov kev ua haujlwm zoo corrosion kuj. Hauv tsab xov xwm no, cia peb tshawb txog qhov no ua ke.
Ua ntej, cov ntaub ntawv carbon fiber yog tsim los ntawm kev kho mob siab graphitization los tsim cov qauv crystalline zoo li graphite. Cov qauv no inherently muaj zoo heev tsis kam mus rau corrosive ib puag ncig, xyuas kom meej tias cov khoom xws li elastic modulus thiab lub zog nyob twj ywm unchanged loj nyob rau hauv nruab nrab xws li acids, alkalis, thiab ntsev. Yog li ntawd, carbon fiber muab kev ruaj ntseg txaus nyob rau hauv cov nqe lus ntawm kev pab cuam lub neej.
Hauv kev siv cov tswv yim, carbon fiber feem ntau yog siv los ntawm cov ntaub ntawv sib xyaw. Cov yam ntxwv xws li cov resin matrix siv ua ke nrog carbon fiber tuaj yeem cuam tshuam qhov corrosion kuj ntawm cov khoom siv fiber ntau. Cov resins sib txawv siv yuav ua rau muaj kev sib txawv corrosion kuj muaj peev xwm ntawm cov khoom siv fiber ntau. Nws tau raug pom nyob rau hauv cov ntaub ntawv siv tau hais tias thaum lub sij hawm molding txheej txheem ntawm cov khoom siv fiber ntau, txhim khu kev kho saum npoo ncaj qha cuam tshuam rau lawv cov corrosion kuj. Kev kho saum npoo zoo tuaj yeem tiv thaiv cov fiber ntau, tiv thaiv kev nkag mus rau nruab nrab. Tau kawg, qhov cuam tshuam corrosion los ntawm cov khoom siv carbon fiber ntau tuaj yeem sib txawv nyob ntawm cov ntawv thov tshwj xeeb.
