Kev hloov pauv ntawm carbon fiber nyob rau hauv huab cua kub
Cov pa roj carbon fiber ntau yog siv dav hauv aerospace, kev tsim tsheb, thiab cov khoom siv ncaws pob vim nws cov khoom siv zoo heev thiab kev tiv thaiv corrosion. Txawm li cas los xij, kev ua haujlwm ntawm carbon fiber nyob rau hauv huab cua kub kuj yog ib qho tseem ceeb hauv kev ntsuas nws qhov kev siv tau. Kab lus no yuav tshawb txog cov kev hloov pauv ntawm cov pa roj carbon fiber ntau nyob rau hauv qhov kub thiab txias ib puag ncig.
Hloov nyob rau hauv ib puag ncig kub
Thermal stability
Cov pa roj carbon fiber nws tus kheej muaj kev kub ntxhov siab. Raws li kev tshawb fawb tau, qhov kub tsis kam ntawm carbon fiber cab tuaj yeem ncav cuag ntau tshaj 1000 degree. Txawm li cas los xij, thaum carbon fiber tau sib xyaw nrog lwm cov ntaub ntawv (xws li epoxy resin) los ua cov pa roj carbon fiber ntau, nws cov cua sov yuav cuam tshuam los ntawm cov ntaub ntawv no. Piv txwv li, epoxy resin yuav pib oxidize thiab decompose ntawm 180 ~ 200 degree, yog li epoxy resin carbon fiber board tsuas tuaj yeem tiv taus qhov kub ntawm 150 degree feem ntau ntawm kev siv tiag tiag.
Kev txhim kho ntawm cov thermoplastic cob
Lub tshav kub tsis kam ntawm carbon fiber board ua los ntawm thermoplastic resin (xws li polyphenylene sulfide, polyetheretherketone, thiab lwm yam) tuaj yeem txhim kho rau qee yam thiab tuaj yeem tiv taus qhov kub ntawm 250 degree. Tsis tas li ntawd, muaj qee cov pa roj carbon fiber ntau ua los ntawm kev ntxiv lwm cov ntaub ntawv kub-resistant rau carbon fiber prepreg, thiab lawv cov kub-kub kuj tuaj yeem txhim kho ntxiv, tab sis feem ntau tsis ntau tshaj 300 degree.

Txias stability
Carbon fiber kuj ua tau zoo heev nyob rau hauv ib puag ncig uas tsis kub. Cov pa roj carbon fiber ntau thiab nws cov ntaub ntawv sib xyaw yuav tsis nkig lossis degrade hauv kev ua tau zoo nyob rau hauv cov xwm txheej txias heev. Qhov no ua rau cov pa roj carbon fiber ntau yog cov khoom siv zoo tshaj plaws rau kev siv hauv qhov chaw txias, xws li hauv Arctic lossis qhov chaw tshawb nrhiav.
Cov ntaub ntawv thov tiag tiag
Nyob rau hauv lub tshav dav hlau, carbon fiber composites feem ntau yuav tsum fim huab cua hloov pauv, los ntawm ib txwm kub nyob rau hauv av mus rau huab cua txias nyob rau hauv lub ntuj, thiab tom qab ntawd mus rau high kub thaum rov nkag mus rau hauv huab cua. Lub peev xwm ntawm cov pa roj carbon fiber ntau los tswj kev ua haujlwm ruaj khov nyob rau hauv qhov kev hloov pauv huab cua no ua pov thawj nws txoj kev ntseeg siab hauv qhov chaw huab cua.
Xaus
Hauv cov ntsiab lus, kev ua tau zoo ntawm cov roj carbon fiber ntau ntawm qhov kub siab yog nyob ntawm hom khoom sib xyaw thiab ib puag ncig uas nws siv. Txawm hais tias carbon fiber nws tus kheej muaj qhov kub thiab txias tsis kam, qhov kub tsis kam ntawm nws cov khoom sib xyaw yuav cuam tshuam los ntawm cov khoom siv matrix. Yog li ntawd, thaum xaiv cov khoom siv carbon fiber ntau, xaiv cov khoom tsim nyog yuav tsum tau ua raws li cov ntawv thov tshwj xeeb thiab cov kev xav tau kub.
