Dab tsi yog qhov txawv ntawm cov ntaub ntawv carbon fiber thiab aramid fiber ntau daim ntaub?

Nyob rau hauv kev txhawb nqa ntawm lub tsev, cov kabmob muaj peev xwm thiab kev ua haujlwm ntev ntawm cov khoom siv fiber ntau sib xyaw yog ntau thiab ntau qhov kev lees paub. Nws qhov zoo yog lub sijhawm tsim kho luv luv, cuam tshuam me ntsis ntawm cov qauv qub, thiab tsis muaj qhov nce ntawm tus kheej qhov hnyav ntawm cov qauv. Los ntawm kev txhim kho txuas ntxiv ntawm cov khoom siv ntxiv, cov ntaub ntawv fiber ntau yog cov tsev neeg loj. Feem ntau siv cov ntaub ntawv fiber ntau hauv kev txhawb nqa yog cov ntaub ntawv carbon fiber thiab aramid fiber ntau daim ntaub, uas muaj cov yam ntxwv sib txawv thiab siv. Lub tsev txhawb nqa hauv qab no yuav qhia rau koj seb qhov txawv ntawm cov ntaub ntawv carbon fiber thiab aramid fiber ntau yog dab tsi?

Txawm hais tias cov ntaub ntawv carbon fiber thiab aramid fiber ntau yog cov khoom siv fiber ntau zoo, muaj qhov sib txawv ntawm lawv lub zog. Piv txwv li, lub zog tensile ntawm cov ntaub fiber ntau tuaj yeem ncav cuag 3400 MPa, thaum lub zog tensile ntawm aramid fiber ntau tuaj yeem ncav cuag 2100 MPa. Los ntawm kev xav ntawm cov khoom siv kho tshuab, cov ntaub ntawv carbon fiber muaj qhov zoo ntawm aramid fiber ntau daim ntaub, tab sis ob qho tib si tuaj yeem ua tau raws li qhov tsis sib xws ntawm cov pob zeb thiab tiv thaiv kev puas tsuaj hauv kev siv tiag tiag.

Carbon fiber ntaub yog conductive. Thaum qhov chaw txhawb zog muaj cov kev cai nruj ntawm hluav taws xob, yuav tsum tau them nyiaj rau seb cov ntaub ntawv carbon fiber puas tuaj yeem siv tau. Aramid fiber ntau daim ntaub yog tsis-conductive thiab haum rau nyob ib puag ncig. Yog hais tias lub subway tunnel xav tau cov ntaub ntawv rwb thaiv tsev thiab cov khoom siv ntxiv, aramid fiber ntau yuav tsum siv cov ntaub ntawv carbon fiber ntau. Tsis tas li ntawd, aramid fiber ntau daim ntaub muaj qhov toughness zoo dua thiab kev cuam tshuam tsis zoo dua li cov ntaub ntawv carbon fiber, thiab yog qhov tsim nyog rau kev siv nyob rau hauv ib puag ncig dynamic load.

Nyob rau hauv qhov kev txhawb nqa ntawm lub tsev, peb yuav tsum xaiv cov khoom siv fiber ntau uas tsim nyog rau kev txhawb nqa raws li qhov xwm txheej tiag tiag. Feem ntau hais lus, cov ntaub ntawv carbon fiber reinforcement tuaj yeem ua tau raws li cov kev xav tau ntawm ntau lub tsev, thiab muaj zog dua thiab muaj kev nyab xeeb, thiab nws tau dhau los ua cov khoom tseem ceeb hauv cov khoom siv fiber ntau. Carbon fiber reinforcement muaj xws li carbon fiber ntaub thiab carbon fiber phaj reinforcement. Ntawm lawv, cov ntaub ntawv carbon fiber reinforcement yog lwm yam tshiab ntawm cov cuab yeej siv cuab yeej cuab tam tom qab nce cov pob zeb thiab cov hlau sib txuas.
