Nrog rau kev nce sai tsis yog ntawm cov tsev xwb, kev txhim kho kev tsim kho tau dhau los ua ib feem tseem ceeb ntawm kev tsim kho kev lag luam. Txawm hais tias tus qauv xav tau los txhim kho lub peev xwm ntawm cov kabmob vim muaj kev hloov pauv lossis kev txhim kho seismic, nws tag nrho yog nyob ntawm kev txhim kho cov txheej txheem. Cov khoom siv txhawb zog siv hauv cov txheej txheem kev txhim kho tsis ncaj qha cuam tshuam rau qhov zoo ntawm kev txhawb nqa los ntawm qhov chaw. Inferior reinforcement cov ntaub ntawv yuav txo tau cov nyhuv reinforcement thiab ua rau kom tsis muaj zog reinforcement, cuam tshuam rau kev nyab xeeb kev ua tau zoo ntawm cov qauv.
Ntawm ntau txoj hauv kev ntxiv dag zog, carbon fiber reinforcement tau maj mam tau txais kev lees paub ntau dua nrog qhov zoo ntawm kev tsim kho, kev ua haujlwm nrawm, thiab kev txhim kho tseem ceeb hauv cov kabmob muaj peev xwm, thiab tau dhau los ua ib txoj hauv kev txhawb nqa ntau tshaj plaws. Cov pa roj carbon fiber ntau tau siv dav thiab muaj kev cuam tshuam loj heev rau kev nyab xeeb ntawm cov qauv. Txhawm rau kom muaj kev nyab xeeb ntawm cov qauv, thaum xaiv cov pa roj carbon fiber ntau, nws yog ib qho tsim nyog yuav tsum xaiv cov pa roj carbon fiber ntau kom tsis txhob muaj kev pheej hmoo ntawm kev nyab xeeb. Niaj hnub no, tus editor yuav qhia txog yuav ua li cas txheeb xyuas qhov zoo thiab qhov tsis zoo ntawm cov paib carbon.
1. Cov khoom siv raw
Cov pa roj carbon fiber ntau yog ua los ntawm carbon fiber prefilaments extruded hauv epoxy nplaum, yog li qhov zoo ntawm carbon fiber prefilaments tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov pa roj carbon fiber ntau. Los ntawm kev xav ntawm cov cab, cov pa roj carbon fiber ntau siv rau kev txhim kho cov txheej txheem yog tag nrho cov 12K cab hlau, thiab cov paib carbon yuav tsum muaj cov ntsiab lus carbon fiber ntau dua los yog sib npaug li 65%, yog li cov pa roj carbon fiber ntau ntawm cov paib carbon ntau dua. los yog sib npaug li 70%, deb tshaj qhov kev cai hauv teb chaws.
Muaj ntau pawg zog sib txawv ntawm cov cab thiab cov ntsiab lus fiber ntau, carbon fiber thiab carbon phaj. Raws li kev tshawb nrhiav, thawj filaments siv rau cov pa roj carbon fiber ntau yog T300 thiab T700, thiab lub zog ntawm ob yog 3530 MPa thiab 4900 MPa nyob rau hauv lem. Hauv qhov tshwj xeeb, qhov yuav tsum tau muaj zog ntawm qib qis I carbon phaj yog 2400 MPa. Nws zoo nkaus li tias lub zog ntawm T300 tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm qib qis I, tab sis qhov no tsis yog li ntawd.
Txawm hais tias nyob rau hauv cov txheej txheem pultrusion los yog vim yog cov ntsiab lus ntawm raw fibers, lub zog ntawm cov pa roj carbon fiber yog txo tom qab tau pultruded rau hauv cov pa roj carbon fiber phaj, thiab qhov txo qis yog qhov tseem ceeb heev. Los ntawm kev ua raws li kev siv T700 carbon fiber filaments thiab tom qab kev txhim kho sai thiab kev tsim kho tshiab, lub zog ntawm cov pa roj carbon fiber ntau tau nce mus rau ntau dua 2800 MPa. Vim lub zog yuav tsum tau thiab kev ruaj ntseg cia saib, cov pa roj carbon daim ntaub los ntawm T700 txhob lo lo ntxhuav yog undoubtedly ib tug zoo guarantee.
2. Pultrusion
Cov txheej txheem pultrusion kuj yog qhov tseem ceeb cuam tshuam rau kev ua haujlwm ntawm cov pa roj carbon fiber ntau. Cov txheej txheem pultrusion yog thawj zaug cuam tshuam nrog lub tshuab pultrusion. Tab sis nyob rau hauv qhov chaw ntawm lub tshuab zoo, nws kuj tseem yuav tsum tau them sai sai rau seb txhua cov hlau nyoos ncaj nraim hauv cov txheej txheem pultrusion. Lub slack ntawm raw hlau yuav ua rau cov pa roj carbon phaj siab tsis sib npaug, ua rau lub zog tensile uas tsis tau raws li tus qauv.
3. Kev soj ntsuam zoo
Kev ruaj ntseg zoo yog sib cais los ntawm cov khoom kuaj tus kheej thiab kev tshuaj xyuas thib peb. Raws li qhov kev pom zoo ntawm kev ua kom zoo ntawm cov hlau nyoos thiab cov txheej txheem pultrusion, tseem muaj qhov tshwm sim ntawm cov pa roj carbon tsis zoo hauv cov txheej txheem tsim khoom, yog li kev tshuaj xyuas tus kheej sab nraud yog qhov tseem ceeb tshaj plaws. Qhov kev tshuaj xyuas tus kheej zoo tshaj plaws thiab kev tawm tsam ntawm kev pov tseg cov khoom tsis zoo thiab tsis txhob muab tso rau hauv kev siv yog qhov tseem ceeb lav rau kev ntseeg siab siv cov pa roj carbon fiber ntau.
Nyob rau tib lub sijhawm, daim ntawv tshaj tawm kev xeem thib peb kuj yog pov thawj ntawm kev ua haujlwm ntawm cov pa roj carbon fiber ntau. Daim ntawv tshaj tawm kev xeem thib peb rov kho qhov kev ua tau zoo ntawm cov khoom los ntawm kev sim ncaj ncees thiab ncaj ncees ntawm cov khoom. Cov ntaub ntawv tshaj tawm kev xeem thib peb raug muab piv, suav nrog cov ntawv tshaj tawm kev xeem niaj hnub, kev txheeb xyuas kev nyab xeeb, cov ntawv ceeb toom tsis muaj tshuaj lom, thiab lwm yam. Tej zaum, xav txog txoj cai ntawm tsab ntawv ceeb toom, cov ntawv tshaj tawm feem ntau yog muab los ntawm lub teb chaws tshuaj ntsuam xyuas yuav muaj kev ntseeg ntau dua. .
