Cov pa roj carbon fiber ntau zoo ib yam li cov ntaub ntawv carbon fiber, uas belongs rau cov khoom siv carbon fiber ntau thiab yog ib hom tshiab ntawm cov khoom siv muaj zog. Cov pa roj carbon fiber phaj yog cov pa roj carbon fiber ntau txheej txheem nyob rau hauv tib txoj kev siv resin infiltration thiab hardening los tsim carbon fiber phaj, uas muaj peev xwm daws tau qhov teeb meem ntawm nyuaj kev tsim kho thiab loj engineering kom muaj nuj nqis ntawm multi-layer carbon fiber ntaub, zoo reinforcement nyhuv thiab yooj yim siv. .
Nyob rau hauv cov kev qhia tshwj xeeb rau kev soj ntsuam kev nyab xeeb ntawm cov khoom siv hluav taws xob siv hluav taws xob, nws tseem yog qib siab I, thiab lub zog tensile ntawm carbon phaj yuav tsum muaj ntau dua lossis sib npaug li 2400MPa, uas yog qis dua lub zog tensile ntawm carbon. fiber ntau ntau dua los yog sib npaug rau 3400MPa, txawm hais tias cov pa roj carbon phaj tau ua kom puas tsuaj, lub zog tsuas tuaj yeem ncav cuag 3000-32000MPa; Ntawm qhov tod tes, cov ntaub ntawv tseem ceeb ntawm cov pa roj carbon phaj thiab cov ntaub ntawv carbon fiber yog carbon fiber precursors, thiab tam sim no carbon fiber precursors tuaj yeem ncav cuag ntau tshaj 5000Mpa, vim li cas lub zog ntawm carbon fiber board tsim los ntawm kev sib xyaw ua ke ntau dua?
Hais txog qhov teeb meem no, peb kuj yuav tsum pib los ntawm qhov kev xav ntawm cov khoom muaj pes tsawg leeg. Cov pa roj carbon fiber ntau yog ua los ntawm carbon fiber precursor thiab epoxy resin extrusion, thiab ntxiv ntawm epoxy resin txo cov ntsiab lus ntawm carbon fiber precursor nyob rau hauv disguise. Nyob rau hauv tus txheej txheem ntawm kev tsim ib tug tag nrho cov quab yuam ntawm cov carbon fiber phaj thiab lub substrate, cov pa roj carbon fiber precursor yog tsuas yog raug rau tensile kev nyuaj siab. Txhawm rau kom ntseeg tau tias lub zog ntawm cov pa roj carbon fiber ntau, cov ntsiab lus ntawm carbon fiber precursor tau dhau los ua qhov tsim nyog lav, yog tias qhov ntim feem ntawm cov precursor nyob rau hauv cov pa roj carbon fiber phaj yog tsawg heev, ces nws yuav tsum tau ua kom lub zog ntawm cov khoom. carbon fiber phaj kom tsis txaus.
Txawm hais tias cov pa roj carbon fiber ntau tsis zoo rau cov ntaub ntawv carbon fiber ntau hauv lub zog, qhov tseeb, qhov kev txhawb zog ntawm ib lub phaj carbon fiber ntau yog sib npaug rau 4-8 cov ntaub ntawv carbon. Thaum peb siv cov pa roj carbon fiber ntau rau kev txhawb nqa, peb tsis tuaj yeem txiav txim siab lub zog, tab sis yuav tsum xaiv raws li qhov xav tau tiag tiag. Tsis tas li ntawd, nyob rau hauv cov pa roj carbon fiber board, cov pa roj carbon fiber precursor thiab cov epoxy resin nyob rau hauv lub composite seem, yuav ua li cas los mus ua kom ob qho tib si tsim ib tug zoo dua composite seem, thiab txhim kho lub zog ntawm ob qho tib si kuj yog ib qho teeb meem uas yuav tsum tau. yuav daws tau nyob rau hauv high-strength carbon fiber board.
