Lub rooj zaum muaj log fais fab, ua ib qho cuab yeej tshiab rau kev txav mus los qeeb, tau maj mam lees paub los ntawm ntau tus neeg laus thiab cov neeg xiam oob qhab. Peb yuav ua li cas thiaj yuav tau ib qholub rooj zaum muaj log hluav taws xob pheej yig?

Ua ib tug neeg paub txog kev lag luam no tau ntau tshaj kaum xyoo, kuv xav pab koj daws qhov teeb meem no los ntawm ntau yam. Thawj qhov uas peb yuav tsum paub yog tias txhua pawg thiab tus neeg siv khoom qhov xwm txheej thiab qhov chaw siv khoom sib txawv, uas kuj ua rau muaj kev sib txawv ntawm cov khoom uas yuav.

Cov ntaub ntawv feem ntau yog muab faib ua cov hlau carbon, txhuas alloy, aerospace titanium txhuas alloy thiab magnesium alloy, carbon fiber

1. Cov khoom siv hlau carbon.

Cov hlau carbon feem ntau yog siv rau hauv cov rooj zaum muaj log hnyav thiab qee lub npe tsim los ntawm cov chaw tsim khoom me me, cov rooj zaum muaj log hnyav siv cov hlau txhawm rau txhim kho qhov nyuaj ntawm lub cev thiab kev tsav tsheb ruaj khov, piv txwv li, ntau lub tsheb thauj khoom loj muaj cov hlau thiab cov tsheb me me tuaj yeem siv txhuas yog tib qho laj thawj, cov chaw tsim khoom me me tsim cov rooj zaum muaj log siv cov hlau vim tias hom kev ua thiab vuam cov txheej txheem no tsis tshua muaj, tus nqi kuj tseem tsawg. Vim li cas cov chaw tsim khoom me me siv cov hlau vim tias lawv xav tau tsawg dua kev ua haujlwm thiab vuam thiab pheej yig dua.

2. Aluminium & titanium-aluminium alloy

Aluminium alloy thiab titanium aluminium alloy, ob yam khoom no nyob hauv feem ntau ntawm kev ua lag luam rau lub rooj zaum muaj log fais fab, lawv yog 7001 thiab 7003 ob hom txhuas sib txawv, uas yog, txhuas nrog lwm cov khoom sib xyaw sib txawv ntxiv rau nws, lawv cov yam ntxwv zoo yog qhov ceev tsawg thiab lub zog siab, zoo plasticity tsis kam thiab corrosion tsis kam, kom muab nws intuitively yog lub teeb thiab muaj zog thiab ua tau zoo, thaum titanium aluminium alloy yog Nws tseem hu ua titanium-aluminium alloy vim nws lub zog thiab corrosion tsis kam. Raws li lub ntsiab lus melting ntawm titanium yog siab heev, ncav cuag 1942 degrees, uas yog ntau dua 900 degrees siab dua li kub, cov txheej txheem ua thiab vuam yog qhov nyuaj heev thiab tsis tuaj yeem tsim los ntawm lub Hoobkas ua me me, yog li lub rooj zaum ua los ntawm titanium-aluminium alloy kim dua. Tus thawj yog tsim rau kev siv tsis tshua muaj thiab txoj kev zoo thiab kev tsav tsheb, thaum cov neeg siv uas siv nws ntau zaus, feem ntau yuav tsum nqa nws, thiab feem ntau tsav tsheb ntawm cov qhov thiab txoj kev bumpy tuaj yeem xaiv lub rooj zaum ua los ntawm titanium-aluminium alloy.

3. Cov hlau magnesium

Cov hlau magnesium yog ua los ntawm magnesium los koom nrog lwm cov ntsiab lus ntawm cov hlau. Nws cov yam ntxwv yog: me me, muaj zog, modulus elasticity siab, zoo dissipation kub, zoo shock absorption, muaj peev xwm tiv taus cov khoom cuam tshuam ntau dua li cov hlau txhuas, feem ntau siv magnesium-aluminium alloy. Magnesium yog cov hlau siv tau yooj yim tshaj plaws, nrog rau qhov hnyav tshwj xeeb li ob feem peb ntawm cov hlau txhuas thiab ib feem plaub ntawm cov hlau, thiab siv magnesium rau cov thav duab rooj zaum muaj logyog npaj los ua kom tiav ntau dua "lub teeb" ntawm lub hauv paus ntawm txhuas.
