Tshawb xyuas cov yam ntxwv ntawm cov khoom siv carbon fiber
Cov pa roj carbon fiber ntau, raws li cov khoom tsim tawm tshiab, tau siv dav hauv ntau qhov chaw. Txawm li cas los xij, cov neeg feem coob tsis paub txog cov yam ntxwv ntawm cov ntaub ntawv carbon fiber. Tsab ntawv xov xwm no yog npaj los muab cov lus qhia dav dav rau cov ntaub ntawv carbon fiber, vam tias yuav ua rau txhua tus nkag siab txog carbon fiber ntau.
Qhov zoo tshaj plaws paub zoo ntawm cov ntaub ntawv carbon fiber yog lawv lub zog siab thiab lub teeb yuag.
Cov ntaub ntawv carbon fiber muaj qhov ntom ntawm tsuas yog 1.7 g / cm3, uas yog tsawg tshaj li ib feem plaub ntawm cov hlau. Txawm li cas los xij, lawv lub zog tensile tuaj yeem ncav cuag ntau dua 3000 MPa, uas yog ob peb zaug siab dua li cov hlau. Qhov tshwj xeeb lub zog thiab cov qauv ntawm cov pa roj carbon fiber ntau tshaj cov khoom siv hauv cov qauv, tso cai rau kev tsim lub teeb yuag thaum tseem ua tau raws li qhov yuav tsum tau muaj zog. Tsis tas li ntawd, carbon fiber yog cov khoom siv anisotropic, nrog rau qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov fiber ntau. Cov yam ntxwv no tso cai rau kev pom zoo tsim ntawm carbon fiber composites los ntawm kev teeb tsa cov txheej txheem hauv kev tawm tswv yim.
Txawm hais tias thermal conductivity ntawm carbon fiber yog qis dua piv rau cov hlau, nws yog qhov siab dua li cov khoom siv organic thiab polymer. Cov cuab yeej no ua rau cov pa roj carbon fiber ntau haum rau cov ntawv thov xws li cov khoom siv hnub ci, cov khoom siv nrog cov cua sov hloov pauv, thiab qhov chaw ua haujlwm kub. Cov pa roj carbon fiber ntau nthuav tawm cov thermal expansion coefficients tsawg, txhais tau tias nws muaj tsawg deformation nrog kev hloov pauv ntawm qhov kub thiab txias, ua kom muaj qhov ruaj khov.
Ua cov khoom siv tsis yog xim hlau, carbon fiber muaj qhov ua haujlwm zoo rau cov organic solvents, acids, thiab alkalis. Cov cuab yeej no ua rau cov khoom siv carbon fiber ntau siv rau hauv ntau qhov chaw ua haujlwm thiab txuas ntxiv lawv lub neej kev pabcuam.
