-Thaum ntxov thaum Tsov Rog Nyab Laj, cov av mines tau ua los ntawm carbon fiber, thiab kaum xyoo tom qab F1 pib siv carbon fiber, thiab tom qab lwm xyoo caum, carbon fiber tau siv rau tsheb kauj vab.Cov keeb kwm ntawm carbon fiber tau ntev, tab sis koj puas paub tiag?
Cov pa roj carbon fiber ntau
Ua ntej tshaj plaws, peb paub txog cov ntaub ntawv carbon fiber ntau, cov pa roj carbon fiber ntau zoo me ntsis, ua ntej siv nws, peb yuav tsum weave cov fibers rau hauv daim ntaub, uas kuj yog cov ntaub ntawv carbon fiber.
Ib-txoj kev ntaub (UD, unidirectional)
Ntau tus neeg xav tias daim ntaub ib leeg tsis zoo thiab pheej yig, tab sis nws tsis zoo li ntawd kiag li. Cov pa roj carbon fiber yog ib pawg ntawm ib pawg, cov pa roj carbon fiber nyob rau hauv ib qho kev coj ua ib kab, yog ib daim ntaub. Qhov no tsuas yog cov txheej txheem carbon fiber ntau thiab tsis muaj dab tsi cuam tshuam nrog qhov zoo ntawm cov khoom siv carbon fiber nws tus kheej. Ib-txoj kev ntaub yog nrov dua nyob rau hauv lub thav duab ntawm lub tsheb kauj vab, lub zog raws li cov kev taw qhia ntawm carbon fiber ntau dua. Ntau qhov chaw ntawm lub tsheb kauj vab yog nyob rau hauv lub zog ntawm cov kev taw qhia sib txawv., yog li cov haujlwm no muaj zog dua thaum ua nrog ib txoj kev ntaub.
Woven Npuag
Feem ntau, woven npuag tau muab faib ua ob peb hom, xws li 1K, 3K, 12K, 1K txhais tau hais tias 1000 ntawm carbon fiber muaj li ntawm ib feem, thiab ces woven; 3K yog 3000, 12K yog 12000, yooj yim to taub.
Modulus
Nyob rau hauv ib txoj kev, modulus yog hardness, lub modulus feem ntau tuaj yeem ua rau peb xav txog kev sib dua thiab muaj zog dua.Qhov siab dua qhov modulus, qhov qis dua qhov deformation uas tshwm sim thaum lubcarbon fiber ntauyog cuam tshuam los ntawm sab nraud rog.Tab sis qhov tseeb thav duab tsim yuav kuj muab lwm yam, xws li kev nplij siab.
Tensile zog
Nws yog lub peev xwm ntawm cov khoom siv lossis cov qauv los tiv thaiv cov khoom uas zoo li elongated, es tsis yog compressive zog, thiab cov load nws dais nyhav txo qhov loj. Hauv lwm lo lus, lub zog tensile resists nro (rub tawm), thaum lub zog compressive resists compression (thov ua ke).
Resin
Cov pa roj carbon fibers muaj lub zog me me kom txog thaum lawv coated nrog cov resin, thiab 3000 carbon filaments tuaj yeem yooj yim ripped nrog tes. tab sis coated nrog resin curing, nws yuav ua nruj dua hlau thiab hlau. Muaj ob txoj hauv kev ntawm txheej txheej, ib qho yog hu ua Prepreg thiab lwm yam yog ib txoj hauv kev. Pre-immersion yog pre-coated nrog resin ua ntej cov ntaub ntawv carbon yog glued rau pwm; txoj hauv kev yog tias cov resin yog coated thaum cov ntaub ntawv carbon yuav siv tau. Kev khaws cia ntawm daim ntaub prepreg yuav tsum nyob rau ntawm qhov kub thiab txias, thaum kho yuav tsum muaj qhov kub thiab txias, kom cov khoom siv carbon fiber ntau yuav muaj zog dua.
