Yog carbon fiber ntau zog dua hlau
Carbon fiber yog ib yam khoom uas tau coj lub ntiaj teb engineering los ntawm cua daj cua dub. Nws yog lub teeb yuag, ruaj thiab ntau yam khoom siv uas tau dhau los ua kev xaiv nrov rau ntau yam lag luam xws li aerospace, automotive, marine, khoom ua si thiab ntau ntxiv. Cov pa roj carbon fiber ntau feem ntau piv rau cov hlau, uas tau siv los ua cov khoom siv rau ntau xyoo. Cov lus nug, txawm li cas los xij, puas yog carbon fiber ntau dua li cov hlau? Hauv tsab ntawv no, peb yuav tshawb xyuas cov khoom ntawm carbon fiber thiab hlau thiab txiav txim siab tias carbon fiber puas muaj zog dua.
Hlau yog cov khoom siv dav siv uas muaj zog, ruaj khov thiab muaj zog tensile siab. Lub zog tensile yog qhov ntsuas ntawm qhov siab tshaj plaws uas cov khoom tuaj yeem tiv taus ua ntej tawg. Hlau tau siv ntau xyoo, thiab nws lub zog thiab ruaj khov tau ua rau nws muaj kev xaiv nrov rau ntau yam kev siv xws li kev tsim kho, tsheb thiab tshuab kev lag luam. Hlau tseem paub txog nws lub peev xwm los tiv thaiv kev khoov thiab deformation.
Ntawm qhov tod tes, carbon fiber yog cov khoom sib xyaw ua ke ntawm ib tus neeg fibers uas tau khi ua ke nrog cov cob. Cov pa roj carbon fiber tau paub tias yog cov khoom siv ultra-hnav, nrog lub zog siab-rau-hnyav piv. Carbon fiber kuj tseem muaj zog dua hlau, nrog lub zog tensile ntau dua. Cov pa roj carbon fiber ntau muaj qhov nruj, uas txhais tau tias nws tsis tuaj yeem khoov lossis deform yooj yim. Cov pa roj carbon fibers yog tsim los ntawm cua sov cov ntaub ntawv uas muaj cov pa roj carbon ntau rau qhov kub thiab txias, ua rau cov fibers uas muaj zog heev thiab hnav.
Ib qho tseem ceeb uas ua rau carbon fiber ntau zog dua hlau yog nws lub zog tensile. Cov pa roj carbon fiber muaj lub zog tensile ntawm 1, 000 MPa (megapascal), thaum hlau muaj lub zog ntawm 400-550 MPa. Qhov no txhais tau hais tias cov pa roj carbon fiber ntau tuaj yeem siv txog li 2.5 npaug ntawm kev ntxhov siab ntau dua li cov hlau ua ntej tawg. Cov pa roj carbon fiber kuj muaj qhov nruj dua, uas txhais tau tias nws yuav tsis yooj yim khoov lossis deform.
Lwm yam uas ua rau carbon fiber ntau zog dua hlau yog nws qhov ntom. Carbon fiber muaj qhov ceev ntawm 1.75 g / cm3, thaum hlau muaj qhov ceev ntawm 7.8 g / cm3. Qhov no ua rau cov pa roj carbon fiber ntau dua li cov hlau, thiab qhov no yog vim li cas carbon fiber yog qhov kev xaiv nrov rau kev siv qhov hnyav yog qhov kev txhawj xeeb.
Txawm hais tias nws lub zog, txawm li cas los xij, carbon fiber muaj ib qho teeb meem loj, thiab qhov ntawd yog nws qhov brittleness. Cov pa roj carbon fiber ntau tuaj yeem tawg tau yooj yim nyob rau hauv kev cuam tshuam tam sim lossis poob siab, tsis zoo li cov hlau, uas muaj peev xwm nqus tau cov zog no ntau dua. Tsis tas li ntawd, cov pa roj carbon fiber kuj zoo li degrade thaum lub sij hawm raug UV teeb los yog ya raws. Qhov no txhais tau hais tias carbon fiber yuav tsum tau khaws cia kom zoo los xyuas kom meej nws lub neej ntev.
Tag nrho cov nyob rau hauv tag nrho cov, carbon fiber yog muaj zog tshaj hlau nyob rau hauv cov nqe lus ntawm tag nrho cov tensile zog thiab ceev. Cov pa roj carbon fiber kuj yog cov khoom siv hnyav uas zoo tagnrho rau kev siv qhov hnyav yog qhov tseem ceeb. Txawm li cas los xij, cov pa roj carbon fiber yog nkig thiab tuaj yeem tawg tau yooj yim nyob rau hauv kev cuam tshuam los yog poob siab, tsis zoo li cov hlau, uas yog qhov zoo dua ntawm absorbing cov rog. Kev txiav txim siab siv carbon fiber lossis hlau thaum kawg yog nyob ntawm daim ntawv thov tshwj xeeb, nrog rau txhua yam khoom muaj nws qhov zoo thiab qhov tsis zoo.
