Tau ntsib qhov teeb meem loj zuj zus ntawm kev ua qias tuaj ib puag ncig, kev paub txog kev tiv thaiv ib puag ncig kev sib raug zoo tau maj mam nce, thiab cov qauv ntawm kev siv cov khoom siv ntuj tsim kuj tau loj hlob.Ib puag ncig tus phooj ywg, lub teeb yuag, kev siv hluav taws xob tsawg thiab cov yam ntxwv txuas ntxiv ntawm cov nroj tsuag fibers tau nyiam ntau yam.Nws yuav txiav txim siab rau yav tom ntej yuav muaj kev txhim kho siab.Txawm li cas los xij, cov nroj tsuag fiber ntau yog cov khoom siv sib txawv nrog cov khoom sib xyaw thiab cov qauv, thiab nws qhov chaw muaj cov hydrophilic hydroxyl pawg.Kev sib raug zoo nrog cov matrix yuav tsum tau kho tshwj xeeb los txhim kho cov khoom ntawm cov khoom sib xyaw.Cog fibers yog siv rau cov khoom sib xyaw, tab sis feem ntau ntawm lawv tsuas yog siv rau cov fibers luv luv thiab cov fibers tsis tu ncua.Thawj cov khoom zoo heev tsis tau siv tag nrho, thiab lawv tsuas yog siv los ua fillers.Yog tias peb tuaj yeem qhia txog kev siv tshuab xaws, nws yog ib qho kev daws teeb meem zoo.Cog fiber ntau woven preforms tuaj yeem muab kev xaiv ntau dua rau cov ntaub ntawv sib xyaw, tab sis tam sim no lawv siv tsawg dua thiab tsim nyog rau kev tshawb fawb thiab kev loj hlob ntxiv.Yog tias peb tuaj yeem rov xav txog txoj kev siv fiber ntau ib txwm siv, thiab qhia cov tswv yim niaj hnub sib xyaw ua ke los txhim kho nws, txhim kho qhov zoo ntawm kev siv thiab txhim kho qhov tsis zoo, nws yuav muaj peev xwm muab cov nroj tsuag fibers tshiab tus nqi thiab kev siv.

Cov nroj tsuag fiber ntau yeej ib txwm sib cais los ntawm tib neeg lub neej txhua hnub.Vim nws cov yam ntxwv yooj yim thiab rov ua tau dua tshiab, cov nroj tsuag fiber ntau tau dhau los ua cov khoom siv tseem ceeb rau tib neeg lub neej.Txawm li cas los xij, nrog kev nce qib ntawm kev siv thev naus laus zis thiab kev loj hlob ntawm kev lag luam petrochemical, tib neeg tsim fibers thiab plastics tau maj mam hloov cov nroj tsuag fibers ua cov khoom siv tseem ceeb vim. qhov zoo ntawm cov cuab yeej tsim khoom tsim tau zoo, cov khoom sib txawv thiab kev ua haujlwm zoo.Txawm li cas los xij, roj av tsis yog cov khoom siv txuas ntxiv dua tshiab, thiab cov teeb meem pov tseg pov tseg tshwm sim los ntawm kev pov tseg ntawm cov khoom zoo li no thiab cov pa phem ntau hauv cov txheej txheem tsim khoom tau ua rau tib neeg rov xav txog kev siv cov khoom siv.Raws li tus qauv ntawm kev tiv thaiv ib puag ncig thiab kev ruaj ntseg, cov nroj tsuag ntuj fibers tau txais kev saib xyuas.Nyob rau hauv xyoo tas los no, cov ntaub ntawv sib xyaw uas siv cov nroj tsuag fibers ua cov ntaub ntawv txhawb zog tau pib tau txais kev saib xyuas.

Cog fiber ntau thiab composite

Cov qauv sib xyaw tuaj yeem tsim los ntawm kev tsim khoom.Lub matrix-wrapped fiber muab ib tug ua tiav thiab cov duab ntawm cov khoom, thiab tiv thaiv lub fiber los ntawm deterioration vim ib puag ncig influences, thiab kuj ua raws li ib tug choj kom hloov kev ntxhov siab ntawm cov fibers;thaum lub fiber nqa feem ntau ntawm sab nraud quab yuam nrog nws cov khoom zoo heev thiab muaj peev xwm dhau Qhov kev npaj 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 fibers feem ntau yog cog cov cell aggregates, thiab cov kab noj hniav thiab qhov khoob hauv qhov no tuaj yeem nqa cov khoom siv hluav taws xob zoo rau cov khoom siv.Nyob rau hauv lub ntsej muag ntawm lub zog sab nraud (xws li kev co), nws kuj tau txais txiaj ntsig los ntawm nws qhov porosity, uas tso cai rau lub zog kom sai sai.Tsis tas li ntawd, ua tiav cov txheej txheem ntawm cov nroj tsuag fiber ntau tawm cov pa phem thiab siv cov tshuaj tsawg dua, muaj qhov ua haujlwm qis dua, muaj qhov zoo ntawm kev siv hluav taws xob tsawg, thiab qib ntawm cov khoom siv thaum lub sij hawm ua haujlwm kuj qis dua;Tsis tas li ntawd, cov nroj tsuag fiber ntau yog cov yam ntxwv Rov ua dua tshiab, kev tsim khoom ruaj khov tuaj yeem ua tiav raws li kev tswj hwm tsim nyog thiab kev tswj hwm.Nrog kev pab los ntawm cov cuab yeej siv niaj hnub no, kev sib tsoo thiab huab cua tsis kam ntawm cov ntaub ntawv tau raug tswj kom zoo, kom lawv tuaj yeem decomposed tom qab cov khoom lag luam lub neej voj voog, tsis ua rau khib nyiab, thiab cov pa roj carbon emissions los ntawm decomposition kuj yog los ntawm kev loj hlob thawj zaug.Cov pa roj carbon monoxide hauv huab cua tuaj yeem yog carbon nruab nrab.
