Lub zog ntawm carbon fiber ntau yog dab tsi? Muaj zog dua hlau

Txoj kev siv feem ntau ua rau cov pa roj carbon fiber ntau yog ua cov pas nrig, cov kav dej, daim hlau, thiab cov khoom zoo li qub. Lub zog ntawm qhov sib txawv tuaj yeem sib txawv heev, nyob ntawm qhov kev ntxhib los mos thiab kev siv tshuab ntawm cov khoom siv fiber ntau. Noj cov roj carbon fiber ntau ua piv txwv, lawv lub zog zoo li cas? Puas yog nws muaj zog dua hlau? Cia peb saib qee cov ntaub ntawv ua ntej.

Kev sib piv ntawm tensile lub zog ntawm carbon fiber, carbon fiber tube, thiab hlau

1. Lub zog tensile ntawm carbon fiber yog 3000MPa;

2. Lub zog tensile ntawm carbon fiber kav ua los ntawm composite nrog resin matrix yog hais txog 1500MPa;

3. Lub zog tensile ntawm cov hlau tsuas yog 300-600MPa;

4. Lub zog tensile ntawm steel kav (xws li Q235) tsuas yog 370MPa-500MP.

Tom qab sib piv cov ntaub ntawv kab rov tav, txhua tus tuaj yeem nkag siab tias zoo li cov pa roj carbon fiber ntau muaj lub zog tensile zoo li no. Hlau yuav zoo li nyuaj, tab sis qhov tseeb, lub zog tensile sib txawv heev.

Dab tsi yog lub hauv paus ntsiab lus ntawm ultra-siab zog carbon fiber raj?

Qhov no pib nrog lub cim ntawm carbon fiber nws tus kheej thiab carbon fiber ntau cov ntaub ntawv.

Ua ntej, nws yog dav ntseeg tias qhov no yog vim qhov zoo ntawm cov pa roj carbon atoms. Tsis tas li ntawd, cov fibers zoo dua, qhov ntau dua nws cov txheeb ze lub zog, vim tias muaj tsawg dua ntawm cov fibers zoo. Nce thaj tsam ntawm cov txheej txheem txheej. Thiab stacking lawv txheej los ntawm txheej tuaj yeem txhim kho qhov hardness modulus ntawm fibers. Fibers nrog siab modulus hardness zoo li nyuaj elasticity, thiab thaum raug rau ib tug loj load, lawv elongation kuj yog heev me me.

Cov ntaub ntawv carbon fiber ntau yog cov carbon fibers uas tau teem rau hauv ib qho kev taw qhia thiab tom qab ntawd sib koom ua ke siv cov resin los ua tag nrho. Nyob rau hauv cov ntaub ntawv carbon fiber ntau, qhov denser cov carbon fibers, ntau cov pa roj carbon fibers tam sim no nyob rau hauv ib chav tsev ntim, thiab siab dua lub zog raws li cov kev taw qhia ntawm cov carbon fibers.

Kev tsim cov pa roj carbon fiber ntau yog ua tiav los ntawm stacking ntau txheej ntawm carbon fiber pre impregnated daim kab xev hauv ntau cov lus qhia, thiab tom qab ntawd siv cov pwm los tsim cov duab tubular, uas yog tsim los ntawm high-temperature molding. Cov khoom siv ntawm cov ntaub nplaum ua ntej impregnated, tus naj npawb thiab cov txheej txheem ntawm cov txheej txheem, thiab cov txheej txheem ua haujlwm siab yog txhua yam uas cuam tshuam rau lub zog ntawm cov kav dej carbon fiber.
