Ntsib cov teeb meem loj zuj zus ntawm ib puag ncig cov pa paug dawb, kev paub txog kev tiv thaiv ib puag ncig muaj maj mam nce, thiab siv cov ntaub ntawv ntuj kuj tau raug nplua. Tus phooj ywg ib puag ncig, lub teeb yuag, cov hluav taws xob tsawg thiab cov yam ntxwv txuas dua tshiab ntawm cov nroj tsuag cov fibers tau nyiam ntau xim. Nws yuav raug txiav txim siab nyob rau hauv lub neej yav tom ntej yuav muaj qib siab ntawm kev txhim kho. Txawm li cas los xij, cog cov fiber ntau yog cov khoom siv heterogeneous nrog cov qauv sib xyaw ua ke thiab cov qauv, thiab nws cov nplaim dej muaj cov pab pawg hydrophilic hydroxylic Hydroxyl pawg. Lub affinity nrog lub matrix yuav tsum muaj kev kho mob tshwj xeeb txhawm rau txhim kho cov khoom ntawm cov composite. Kev siv cov fibers yog siv rau cov khoom siv sib xyaw, tab sis feem ntau ntawm lawv txwv tsis pub luv luv fibers thiab cov lus tsis sib xws. Cov khoom qub zoo tshaj plaws tsis tau siv tag nrho, thiab lawv tsuas yog siv los ua cov fillers. Yog tias peb tuaj yeem qhia txog kev ua haujlwm tab sis tea, nws yog cov tshuaj zoo. Nroj fiber ntau woven preforms tuaj yeem muab cov khoom siv sib xyaw ntau ntxiv rau cov khoom siv sib xyaw, tab sis tam sim no lawv siv tsawg dua thiab tsim nyog tshawb fawb ntxiv thiab kev txhim kho. Yog tias peb tuaj yeem Rethink cov qauv siv hluav taws xob tso cai, thiab qhia cov ntsiab lus siv tshuab hluav taws xob kom txhim kho nws, nws yuav muaj peev xwm muab cov khoom siv rau cov khoom siv tshiab thiab cov ntawv thov.
Cov nroj tsuag muaj cov fiber ntau yeej ib txwm muaj kev sib luag los ntawm tib neeg lub neej txhua hnub. Vim nws cov yam ntxwv yooj yim thiab txuas ntxiv tau ua ib qho khoom siv tsis tseem ceeb. Cov khoom lag luam muaj kev txhim kho maj, cov khoom lag luam sib txawv thiab cov khoom siv sib txawv. Txawm li cas los xij, roj av tsis yog cov peev txheej txuas ntxiv, thiab cov pa paug khib nyiab loj rau tib neeg tau ua rau tib neeg siv cov ntaub ntawv siv. Raws li kev hloov pauv ntawm kev tiv thaiv ib puag ncig thiab kev ruaj ntseg, ntuj cog cov laj kab tau rov qab ua tib zoo mloog. Nyob rau hauv xyoo tsis ntev los no, cov ntaub ntawv sib xyaw uas siv cov nroj tsuag cov khoom siv ua cov khoom siv lub zog tau pib tau txais kev saib xyuas.
Nroj Fiber thiab Composite
Tus qauv sib xyaw ua ke tuaj yeem tsim los ntawm kev tsim khoom. Cov Matrix-qhwv fiber ntau muab cov duab ua tiav thiab tiv thaiv cov khoom cuam tshuam rau ib puag ncig vim yog ib puag ncig kev ntxhov siab ntawm cov fibers; Thaum lub sij hawm lub fiber muaj feem ntau ntawm lub zog sab nraud nrog nws cov kws kho zoo heev thiab tuaj yeem dhau cov txheej txheem tshwj xeeb ua tiav cov haujlwm sib txawv. Vim nws lub zog qis thiab muaj zog, cog fiber ntau tuaj yeem txhim kho cov khoom siv tshuab thiab ua kom qis dua thaum nws tau ua rau hauv Frp Composites. Tsis tas li ntawd, cov nroj tsuag cov fibers feem ntau cog cell aggregates, thiab cov kab noj hniav thiab khoob ntawm cov khoom siv kub hauv cov khoom siv. Hauv lub ntsej muag ntawm lub zog sab nraud (xws li kev co sab nraud), nws tseem muaj txiaj ntsig los ntawm nws cov porosity, uas tso cai rau lub zog kom sai sai. Tsis tas li ntawd, cov txheej txheem ua tiav ntawm cov nroj tsuag muaj zog ntawm cov tshuaj tsis zoo, muaj qhov ua haujlwm tsawg dua, muaj cov qib kev ua haujlwm tsawg dua, thiab cov qib kev ua haujlwm tsawg dua, thiab cov qib kev ua haujlwm tsawg dua, thiab cov qib kev ua haujlwm tsawg dua thaum lub sijhawm ua tau qis dua; Ib qho ntxiv, cog fiber yog cov yam ntxwv txuas dua tshiab, kev siv khoom kom ruaj khov tuaj yeem ua tiav raws li kev tswj hwm tsim nyog thiab tswj. Nrog kev pab ntawm cov kev pab niaj hnub no, cov txheej txheem huab cua thiab lawv tuaj yeem tsim kev puas tsuaj tom qab kev txiav txim siab tau zoo, thiab cov carbon emitted los ntawm kev txiav txim siab yog kuj tau los ntawm kev loj hlob thawj zaug. Cov pa roj carbon chaw nyob rau hauv cov huab cua yuav yog carbon nruab nrab.
