Carbon fiber yog ib cov khoom siv muaj zog zoo. Cov khoom lag luam ua los ntawm carbon fiber muaj teeb meem tseem ceeb ua kom pom muaj lub zog tshwj xeeb, muab cov ntawv thov tseem ceeb tshaj plaws. Txawm li cas los xij, kev sib tham txog carbon fiber ntau ntau tsa cov lus nug: Puas yog nws ua txhaum? Puas yog nkig? Cia peb tshawb cov lus nug no hauv kev nthuav dav.
Puas muaj carbon fiber ntau yuav tawg?
Cov neeg carbon fiber yog tsis yooj yim, tab sis carbon fiber composites yog cov muaj kev cuam tshuam rau khoov thiab pob txha lov.
Ib qho carbon fiber fiber fiber heev yog hais txog ib-peb lub thickness ntawm tib neeg cov plaub hau-nyias txaus rau snap nrog cov ntiv tes siab tsawg. Txawm li cas los xij, qhov no yog siv tsuas yog rau tus kheej strands. Thaum ntau txhiab tus ua tiav no yog sib xyaw ua ke rau hauv cov khoom siv
Piv txwv li, cov teeb roj carbon fiber ntau faib sab nraud cov rog hla ntau txhiab tus ua haujlwm txuas ntxiv. Txawm hais tias ib co filaments tawg nyob rau hauv kev ntxhov siab, txheej txheem txheej txheem tag nrho khaws nws ncaj ncees. Cov qauv tsim no muab cov roj carbon fiber ntau lub tensile lub zog tsib zaug ntau dua li cov hlau, ua rau lawv muaj kev puas tsuaj hauv qab.
Puas muaj carbon fiber nkab?
Lo lus "brittle" feem ntau sib tshooj nrog "nquag tawg," tab sis Carbon Fiber kev coj cwj pwm yog nyob ntawm nws daim ntawv thov thiab Engineering:
Zoo tshaj qhov kev ua tau zoo:
Carbon Fiber composites Far cov tshuaj tiv thaiv nyob rau hauv khoov tsis kam. Cov raj roj carbon fiber, piv txwv, tuaj yeem tiv thaiv ntau dua khoov cov tub rog ntau dua li cov raj txij ntawm lub cev hnyav dua.
Brittle tsis ua tiav ntawm kev txwv:
Thaum raug rau cov tub rog dhau nws cov qauv kev txwv, cov roj carbon fiberites tsis dhau dheev tsis yog qhov plasticating plastically es tsis yog deforming plastically. Qhov kev tsis txaus siab no yog feem ntau sau npe tias yog "nkig."
Kev Ua Tes Taw
NojT300 Carbon FiberUa piv txwv:
Lub zog flexural: 1,300 MPa
FLEXURAL Modulus: 140 GPA
Cov kev ntseeg siab no deb ntawm cov hlau feem ntau. Los ntawm kev ua kom zoo fiber ntau nteg (piv txwv li, kho cov kev qhia fiber ntau thiab cov chaw tsim khoom), txuas ntxiv txhim kho kev lag luam tsis kam thiab ua kom ntev.
Tseem Ceeb Takaway
Carbon Fiber tus perceiving brittleness stems los ntawm nws daim ntawv raw fws. Thaum engineered rau hauv cov composites, nws hloov mus rau cov khoom muaj zog uas sib npaug tsim nrog lub zog tshwj xeeb. Thaum nws tuaj yeem fracture kev puas tsuaj yog tias muaj cov txheej txheem tsim nyog, tsim nyog tsim ua kom nws ntseeg tau tias cov cuab yeej siv ntaus pob ncaws pob.
Hauv ntej:Tus neeg cov fibers yog muag heev, tab sis cov composites nyuaj.Cov khoom siv "Brittleness" yog kev ua lag luam tawm rau nws lub zog tsis sib xws-rau-qhov hnyav sib piv los ntawm kev sib cav sib ceg.
