Carbon Fiber vs Aluminium

Cov pa roj carbon fiber yog hloov cov txhuas hauv ntau daim ntawv thov thiab tau ua li ntawd rau ob peb lub xyoo dhau los. Cov fibers no paub txog lawv lub zog tshwj xeeb thiab rigidity thiab kuj yog qhov hnyav heev. Cov pa roj carbon fiber ntau yog ua ke nrog ntau yam resins los tsim cov khoom sib xyaw. Cov ntaub ntawv sib xyaw no siv qhov zoo ntawm cov khoom ntawm fiber ntau thiab cob. Kab lus no muab kev sib piv ntawm cov khoom ntawm carbon fiber piv rau txhuas, nrog rau qee qhov zoo thiab qhov tsis zoo ntawm txhua yam khoom.

Carbon Fiber vs Aluminium Ntsuas

Hauv qab no yog cov ntsiab lus ntawm cov khoom sib txawv siv los sib piv ob cov ntaub ntawv:

Modulus ntawm elasticity = "txhim kho" ntawm cov khoom. Qhov piv ntawm kev ntxhov siab rau lub zog rau ib yam khoom. Txoj kab nqes ntawm qhov kev ntxhov siab vs strain nkhaus rau cov khoom hauv nws thaj tsam elastic.

Lub zog tensile kawg = qhov siab tshaj plaws ntawm cov khoom siv tuaj yeem tiv taus ua ntej tawg.

Density = cov khoom loj ntawm ib chav tsev ntim.

Cov tawv nqaij tshwj xeeb = Modulus ntawm elasticity muab faib los ntawm cov khoom ntom ntom. Siv los sib piv cov ntaub ntawv nrog qhov sib txawv ntawm qhov sib txawv.

Lub zog tensile tshwj xeeb = Tensile lub zog muab faib los ntawm cov khoom siv ceev.

Nrog rau cov ntaub ntawv no hauv siab, daim ntawv qhia hauv qab no piv cov carbon fiber thiab txhuas.

Lus Cim: Ntau yam tuaj yeem cuam tshuam cov lej no. Cov no yog generalizations; tsis yog kev ntsuas kiag li. Piv txwv li, cov ntaub ntawv sib txawv ntawm cov khoom siv carbon fiber ntau muaj nrog ntau zog los yog lub zog, feem ntau nrog kev lag luam tawm hauv kev txo qis ntawm lwm yam khoom.

Daim ntawv qhia no qhia tau hais tias cov pa roj carbon fiber ntau muaj lub zog tensile ntawm kwv yees li 3.8 npaug ntawm txhuas thiab ib qho kev nruj ntawm 1.71 npaug ntawm txhuas.

Sib piv thermal zog ntawm carbon fiber thiab txhuas

Ob qho khoom ntxiv uas qhia qhov sib txawv ntawm carbon fiber thiab txhuas yog thermal expansion thiab thermal conductivity.

Thermal expansion piav qhia txog yuav ua li cas cov khoom siv qhov ntev hloov thaum kub hloov.

Aluminium muaj kwv yees li rau lub sij hawm thermal expansion ntawm carbon fiber.

Pros thiab Cons

Thaum tsim cov khoom siv siab heev thiab cov tshuab, cov engineers yuav tsum txiav txim siab seb cov khoom siv twg yog qhov tseem ceeb tshaj plaws rau cov kev siv tshwj xeeb. Thaum muaj zog-rau-hnyav lossis siab tawv-rau-hnyav teeb meem, carbon fiber yog qhov kev xaiv pom tseeb. Hais txog kev tsim qauv, thaum ntxiv qhov hnyav tuaj yeem ua rau lub neej luv lossis ua rau kev ua haujlwm tsis zoo, cov neeg tsim qauv yuav tsum saib carbon fiber ntau li cov khoom siv hauv tsev zoo dua. Thaum toughness yog qhov tseem ceeb, carbon fiber tau yooj yim ua ke nrog lwm cov ntaub ntawv kom tau txais cov yam ntxwv tsim nyog.

Cov pa roj carbon fiber ntau cov khoom siv hluav taws xob tsawg yog qhov muaj txiaj ntsig zoo thaum tsim cov khoom lag luam uas xav tau qib siab ntawm qhov tseeb, thiab qhov ruaj khov nyob rau hauv cov xwm txheej uas kub hloov pauv: cov khoom siv kho qhov muag, 3D scanners, telescopes, thiab lwm yam.

Kuj tseem muaj qee qhov tsis zoo rau kev siv carbon fiber. Carbon fiber tsis tawm los. Nyob rau hauv lub load, carbon fiber yuav khoov tab sis yuav tsis mus tas li raws li cov duab tshiab (elastic). Thaum lub zog tensile kawg ntawm cov khoom siv carbon fiber ntau tshaj cov pa roj carbon fiber tsis tau dheev. Cov kws tsim khoom yuav tsum nkag siab txog tus cwj pwm no thiab suav nrog cov xwm txheej kev nyab xeeb los suav rau nws thaum tsim khoom. Cov pa roj carbon fiber ntau kuj tseem kim dua li txhuas vim yog tus nqi siab los tsim cov pa roj carbon fiber ntau thiab cov txuj ci zoo thiab kev koom tes hauv kev tsim cov khoom zoo sib xws.
