Nrog kev nthuav dav txuas ntxiv ntawm daim ntawv thov kev lag luam, thermosetting cob raws cov roj carbon fiber sib xyaw maj mam qhia lawv tus kheej cov kev txwv, uas tsis tuaj yeem ua tau raws li qhov xav tau ntawm daim ntawv thov siab kawg hauv kev hnav tsis kam thiab tiv taus kub. Hauv qhov no, cov xwm txheej ntawm cov thermoplastic cob raws cov roj carbon fiber sib xyaw tau nce zuj zus, dhau los ua lub zog tshiab ntawm cov khoom sib xyaw ua ke. Xyoo tsis ntev los no, Suav cov tshuab siv roj carbon fiber tau tsim kev txhim kho sai, thiab kev siv thev naus laus zis ntawm cov thermoplastic carbon fiber composites kuj tseem tau txhawb ntxiv.

Hauv kev tshawb nrhiav cov pa roj carbon txuas ntxiv txuas ntxiv cov thermoplastic pre preg, peb qhov kev hloov pauv ntawm kev siv cov thermoplastic carbon fiber tau pom tseeb.

1. Los ntawm cov hmoov carbon fiber ntxiv rau cov pa roj carbon txuas ntxiv
Cov roj carbon fiber ntau tuaj yeem muab faib ua cov hmoov carbon fiber, txho cov roj carbon fiber, ib leeg tsis tu ncua cov pa roj carbon fiber thiab cov ntaub carbon fiber txhawb nqa. Lub fiber ntau ntxiv ntev dua, lub zog ntau dua yog muab los ntawm kev siv thauj khoom, thiab siab dua tag nrho lub zog ntawm kev sib xyaw. Yog li ntawd, piv nrog cov hmoov lossis cov roj carbon fiber ntau ntxiv cov thermoplastic sib xyaw, cov pa roj carbon txuas ntxiv siv cov thermoplastic sib xyaw muaj qhov ua tau zoo dua. Kev siv tshuaj txhaj tshuaj ntau tshaj plaws hauv Suav teb yog hmoov lossis txhoov cov roj carbon fiber ntau ntxiv. Kev ua tau zoo ntawm cov khoom muaj qee yam txwv. Thaum siv cov roj carbon txuas ntxiv txuas ntxiv, cov thermoplastic carbon fiber sib xyaw ua ke yuav nthuav dav rau qhov chaw thov dav.

2. Kev txhim kho los ntawm qhov kawg cov thermoplastic cob rau nruab nrab thiab siab kawg thermoplastic resin matrix
Thermoplastic resin matrix qhia pom viscosity siab thaum txheej txheem yaj, uas nyuaj rau nkag mus rau tag nrho cov ntaub ntawv carbon fiber, thiab qib ntawm kev nkag mus yog cuam tshuam nrog kev ua tiav ntawm prepreg. Txhawm rau txhawm rau txhim kho kev ntub dej ntxiv, cov txheej txheem hloov kho thev naus laus zis tau txais, thiab cov khoom siv hluav taws xob qub tau nthuav tawm thiab cov cuab yeej siv tshuaj txau tau txhim kho. Thaum txuas ntxiv qhov dav ntawm cov pa roj carbon fiber, qhov txuas ntxiv txuas ntxiv ntawm cov tshuaj tau nce ntxiv. Kev ntub dej ntawm cov thermoplastic cob ntawm cov pa roj carbon dimension tau pom tseeb txhim kho, thiab kev ua tau zoo ntawm cov pa roj carbon txuas ntxiv siv cov thermoplastic prepreg tau lees paub zoo. Cov tshuaj sib xyaw ua ke ntawm cov pa roj carbon fiber ntau txuas ntxiv tau ua tiav los ntawm PPS thiab PA mus rau PI thiab saib.

3. Los ntawm kev sim xuas tes ua kom ruaj khov ntau lawm
Los ntawm kev ua tiav ntawm kev sim me me hauv chav kuaj mus rau qhov ruaj khov tsim ntau hauv kev cob qhia, qhov tseem ceeb yog tsim thiab hloov kho cov cuab yeej tsim khoom. Txawm hais tias cov pa roj carbon txuas ntxiv txuas ntxiv cov thermoplastic prepreg tuaj yeem ua tiav cov khoom lag luam ruaj khov nyob tsis yog tsuas yog nyob rau qhov nruab nrab txhua hnub tso tawm, tab sis kuj tseem nyob ntawm qhov zoo ntawm prepreg, uas yog, seb cov ntsiab lus ntawm cov yas hauv prepreg tuaj yeem tswj tau thiab kev faib ua feem tsim nyog, cov pa roj carbon fiber hauv prepreg tau muab faib sib npaug thiab ntxig ntxig rau hauv, thiab seb cov nplais ntawm prepreg tau du thiab qhov loj yog qhov tseeb.
