Fabrication ntawm prepreg

Cov pa roj carbon prepreg yog tsim los ntawm cov fiber ntev txuas mus tas li thiab cov tsis tau kho dua tshiab. Nws yog daim ntawv siv feem ntau siv raw khoom los ua cov khoom ua tau zoo. Prepreg daim ntaub yog tsim los ntawm cov kab uas muaj fiber ntau uas muaj cov yas tsis xeb. Cov pob fiber ntau yog thawj zaug sib dhos rau hauv cov ntsiab lus xav tau thiab dav, thiab tom qab ntawd cov fibers tau sib npaug sib npaug los ntawm cov kab hluav taws xob. Nyob rau tib lub sijhawm, cov kua nplaum tau rhaub thiab lo rau ntawm daim ntawv tso rau sab saud thiab qis dua. Cov ntawv fiber ntau thiab sab saud thiab qis dua tso rau hauv cov ntawv tau qhia rau hauv cov menyuam tib lub sijhawm. Cov fiber ntau nyob nruab nrab ntawm daim ntawv tso tawm sab saud thiab qis dua, thiab cov tshuaj sib tov sib npaug ntawm cov fibers los ntawm kev siab ntawm cov menyuam. Tom qab cov roj hmab uas tsis tau muab ntxhua kom txias lossis qhuav, nws tau dov mus rau hauv cov duab los ntawm cov coiler. Cov roj hmab uas tsis muaj cov roj hmab nyob ib puag ncig los ntawm daim ntawv sab saud thiab qis dua hu ua carbon fiber prepreg. Cov ntawv npaj ua ntej yuav tsum tau ua kom gelatinized mus rau theem ntawm cov tshuaj tiv thaiv ib nrab hauv qab tswj qhov kub thiab txias ib puag ncig. Lub sijhawm no, cov kua nplaum tau khov, uas hu ua B-stage.

Feem ntau, thaum ua cov pa roj carbon fiber prepreg daim ntaub, cov tshuaj siv ob hom. Ib qho yog kom ncaj qha cov cua sov kom txo nws cov viscosity thiab pab txhawb kev faib tawm ntawm cov fibers, uas yog hu ua kub yaj nplaum txheej txheem. Lwm qhov yog txhawm rau yaj cov kua rau hauv cov dej kom txo tau cov viscosity, thiab tom qab ntawd ua kom sov nws tom qab cov tshuaj tau lim nrog cov fiber ntau los ua kom cov flux, uas hu ua flux method. Hauv cov txheej txheem kub yaj cov txheej txheem, cov ntsiab lus ntawm cov kua yog ib qho yooj yim los tswj, cov txheej txheem kom qhuav tuaj yeem raug tso tseg, thiab tsis muaj qhov seem ntws tawm, tab sis cov kua viscosity siab, uas yog ib qho yooj yim ua rau fiber ntau deformation thaum impregnating fiber braids. Txoj hauv kev hnyav muaj cov peev txheej qis thiab txheej txheem yooj yim, tab sis kev siv flux yog qhov yooj yim kom nyob twj ywm hauv qhov kev npaj ua ntej, uas cuam tshuam rau lub zog ntawm kev sib xyaw zaum kawg thiab ua rau muaj kuab paug ib puag ncig.

Cov hom carbon fiber prepreg daim ntaub suav nrog unidirectional carbon fiber prepreg daim ntaub thiab woven carbon fiber prepreg daim ntaub. Unidirectional carbon fiber prepreg daim ntaub muaj lub zog zoo tshaj plaws nyob rau hauv cov lus qhia fiber ntau thiab feem ntau yog siv rau laminated daim hlau ua ke nyob rau hauv cov lus qhia sib txawv, thaum woven carbon fiber prepreg daim ntaub muaj ntau txoj kev weaving, thiab nws lub zog yog hais txog tib yam hauv ob qho lus qhia, yog li nws tuaj yeem siv rau cov txheej txheem sib txawv.

peb tuaj yeem muab nrog carbon fiber prepreg raws li koj xav tau

Kev npaj ntawm prepreg

Cov cob ntawm cov pa roj carbon fiber prepreg yog nyob rau theem ntawm cov tshuaj tiv thaiv ib nrab, thiab yuav txuas ntxiv mus rau tshuaj tiv thaiv thiab kho ntawm chav sov. Feem ntau nws yuav tsum tau khaws cia hauv qhov chaw kub tsawg. Lub sijhawm uas cov pa roj carbon fiber prepreg tuaj yeem khaws cia hauv chav sov tau hu ua lub voj voog cia. Feem ntau, yog tias tsis muaj cov khoom siv ntsuas kub tsawg, qhov ntau lawm ntawm prepreg yuav tsum raug tswj nyob hauv lub voj voos cia thiab tuaj yeem siv tau.
