Dab tsi yog carbon fiber phaj ua los ntawm? Dab tsi yog cov yam ntxwv ntawm cov pa roj carbon fiber ntau?

Muaj ntau txoj hauv kev los ua cov ntawv carbon fiber ntau, tab sis nyob rau hauv ob qho tib si, cov khoom tseem ceeb ntawm daim ntawv yog cov carbon fiber filament thiab resin matrix. Cov pa roj carbon fiber ntau muaj zog dua li cov pa roj carbon fiber ntau, tab sis lawv tsis tuaj yeem siv ib leeg. Cov resin matrix ua raws li cov nplaum los tuav lawv ua ke.

Cov pa roj carbon fiber nws tus kheej yog oxidized los ntawm cov organic fiber, nws muaj ntau tshaj li 90% ntawm high-lub zog cov ntaub ntawv, nws yog vim lub ultra-high mechanical zog ntawm carbon fiber, uas tsuas yog muaj tam sim no kub carbon fiber khoom. Resin matrix cov ntaub ntawv uas nquag siv yog epoxy resin, bis maleimide resin, polyphenylene sulfide resin, polyether ether ketone resin, thiab lwm yam.

Dab tsi yog qhov zoo ntawm carbon fiber phaj kev ua tau zoo?

1, tsawg ntom: carbon fiber filament thiab resin matrix ceev tsis siab, ua los ntawm carbon fiber daim ntawv ceev tsuas yog hais txog 1.7g / cm3, qis dua qhov ntom ntawm txhuas, thiab yog ib qho kev xaiv zoo rau kev lag luam tsim khoom;

2, siab zog modulus: lub zog thiab modulus kev ua tau zoo ntawm cov pa roj carbon fiber phaj yog qhov siab, tab sis lawv nyuaj rau muaj nyob rau tib lub sijhawm, yog li muaj qhov sib txawv ntawm kev siv lub zog siab, siab modulus carbon fiber phaj;

3, zoo kam rau ua: carbon fiber phaj tuaj yeem tiv taus cov kua qaub thiab alkali cov kuab tshuaj, cov dej hiav txwv tsis sib haum, thiab qhov kub thiab txias ib puag ncig kuj muaj kev ua siab ntev, siv ntau qhov chaw, kev pab lub neej ntev;

Cov pa roj carbon fiber phaj los ntawm kev siv cov pa roj carbon fiber ntau, nrog lub zog siab, thiab cov khoom siv elastic siab, los ntawm kev ua kom lub zog, ntawm cov pa roj carbon fiber board, tsim thawj zaug ua ntej nro, ib feem siv los sib npaug ntawm cov nqaj qub load, yog li txo qhov tawg. dav, thiab txhim kho lub ncua kev puas tsuaj ntawm kev ua tau zoo nce tus qauv rigidity, txo cov deflection ntawm cov qauv, alleviate lub strain ntawm lub internal reinforcement, nce lub yield load ntawm reinforcement thiab qhov kawg bearing peev xwm ntawm cov qauv.

1, piv nrog cov tsoos carbon fiber ntaub reinforcement

(1) Cov ntawv carbon fiber ntau yog qhov tsim nyog rau kev siv lub zog ua kom muaj zog, thiab tuaj yeem muab kev ua si tag nrho rau lub zog siab ntawm carbon fiber;

(2) Cov pa roj carbon fiber ntau yog yooj yim kom cov fiber ntau ncaj dua li cov ntaub ntawv carbon fiber ntau, uas yog qhov tsim nyog rau kev ua haujlwm ntawm carbon fiber ntau; Ib txheej ntawm 1.2 hli tuab phaj yog sib npaug rau 10 txheej ntawm cov ntaub ntawv carbon fiber, uas muaj zog dua.

(3) Kev tsim kho yooj yim

2, piv nrog cov tsoos paste steel phaj los yog ua kom cov pob zeb ua kom muaj zog

(1) Lub zog tensile yog 7-10 npaug ntawm cov hlau ntawm tib seem, thiab nws muaj zog corrosion kuj thiab durability piv nrog steel;

(2) Cov duab thiab qhov hnyav ntawm cov khoom siv yog qhov pib tsis hloov tom qab kev txhawb nqa.

(3) Lub teeb yuag, yooj yim siv, yooj yim rau kev khiav lag luam, thiab tsis xav tau cov cuab yeej siv tshuab loj.
