Carbon fiber ntau textures los ntawm kev ua tau zoo ntawm qhov pom

Views:143 Author: Linda Tshaj Tawm Sijhawm: 2022-07-13 keeb kwm:

        Thawj qhov kev xav ntawm cov khoom siv fiber ntau yog txias, nrog kev nkag siab ntawm kev zam thiab thev naus laus zis. Muaj ntau yam khoom uas ua raws li cov tsos ntawm carbon fiber kev ntxhib los mos. Nyob rau hauv qhov tseeb, lub sij hawm txoj kev ntawm carbon fiber muaj ib tug loj daim card. Niaj hnub no, cia peb tham txog qhov sib txawv ntawm qhov sib txawv carbon fiber ntau textures thaum peb ua cov khoom siv fiber ntau.

         Ua ntej tshaj plaws, peb paub tias thaum carbon fibers raug tsim, lawv tsis tsim ib qho los ntawm ib qho, tab sis cov pob khoom, yog li tus naj npawb ntawm carbon fibers muaj nyob rau hauv txhua pob yuav txawv me ntsis, tab sis feem ntau nws tuaj yeem muab faib ua 1000 thiab 3000., 6000, 12000, uas yog, peb paub txog cov ntsiab lus ntawm 1k, 3k, 6k, 12k thiab lwm yam. Cov pa roj carbon fiber ntau feem ntau tuaj nyob rau hauv daim ntawv ntawm cov ntaub npuag, uas ua rau nws yooj yim rau kev ua haujlwm nrog thiab tuaj yeem muab lub zog ntxiv nyob ntawm daim ntawv thov. Yog li ntawd, muaj ntau ntau weaves rau carbon fiber fabrics. Feem ntau yog cov weave tiaj, twill weave thiab satin weave, uas peb yuav nthuav dav nyias. Lub tiaj tiaj tiaj carbon fiber panels saib symmetrical thiab muaj ib tug me me checkerboard-inspired saib. Nyob rau hauv no weaving, tus cab yog woven nyob rau hauv ib tug up / down qauv. Qhov sib nrug nruab nrab ntawm cov hlua sib txuas yog me me, muab lub tiaj weave siab stability. Fabric stability yog lub peev xwm ntawm cov ntaub los tuav nws lub kaum sab xis thiab fiber ntau orientation. Vim nws qhov kev ruaj ntseg siab, cov ntaub qhwv tsis tshua haum rau laminations nrog cov contours nyuaj thiab nws yuav tsis hloov pauv raws li qee qhov sib txawv. Feem ntau, cov ntaub npuag dawb yog tsim rau cov duab ntawm cov ntawv tiaj tus, cov hlab thiab 2D nkhaus qauv.

Twill weave

       Twill yog ib qho kev sib txuas ntawm cov ntaub qhwv dawb thiab satin weave, uas peb yuav tham hauv qab no. Twill muaj qhov hloov tau zoo, tuaj yeem tsim rau hauv cov silhouettes nyuaj, thiab yog qhov phem dua li satin weave ntawm kev tuav cov ntaub ruaj khov, tab sis tsis zoo li cov ntaub dawb. Yog hais tias koj ua raws li ib tug cab nyob rau hauv ib tug twill weave, nws mus los ntawm ib tug tej yam tus naj npawb ntawm cov cab thiab ces mus los ntawm tib tus naj npawb ntawm cov cab. Cov qauv tshaj / hauv qab tsim cov tsos ntawm kab pheeb ces kaum hu ua "twill kab". Piv nrog rau cov weave dawb, qhov ntev ntawm qhov kev ncua deb ntawm kev sib cuam tshuam txhais tau tias tsawg dua crimp thiab tsis tshua muaj kev ntxhov siab.

        2x2 twill yog qhov zoo tshaj plaws paub cov pa roj carbon fiber ntau hauv kev lag luam. Nws yog siv nyob rau hauv ntau daim ntawv thov sab nrauv thiab zoo nkauj, tab sis kuj muaj kev ua haujlwm zoo heev, nws muaj kev tsim qauv thiab nruab nrab stability. Raws li 2x2 lub npe qhia, txhua tus cab yuav nqis los ntawm 2 tus cab thiab nce mus txog 2 tus cab. Ib yam li ntawd, 4 x 4 twill yuav nqes los ntawm 4 tus cab thiab tuaj txog 4 tus cab. Nws muaj me ntsis formability ntau dua 2x2 twill vim lub weave tsis nruj, tab sis lub stability kuj qis dua.

satin ntaub

      Satin weave muaj keeb kwm yav dhau los hauv cov ntaub, thiab tau siv los tsim cov ntaub lo lo ntxhuav uas muaj drape zoo heev thaum tseem saib du thiab seamless. Rau kev sib xyaw ua ke, cov ntaub qhwv no txhais tau tias nws tuaj yeem tsim tau yooj yim thiab qhwv cov contours. Vim qhov yooj yim formability ntawm cov ntaub, nws stability yog tsawg. Feem ntau cov hlua khi satin weaves yog 4-strand satin (4HS), 5-strand satin (5HS) thiab 8-strand satin (8HS). Raws li tus naj npawb ntawm satin weaves nce, formability yuav nce thiab ntaub stability yuav txo.

       Tus lej hauv lub npe cab satin qhia tag nrho cov cab uas hla thiab nqis. Rau 4HS nws yuav mus dhau 3 rub nce, ces 1 rub down. Rau 5HS nws yuav dhau 4 tus rub, tom qab ntawd 1 rub down, thaum 8HS yuav hla 7 tus rub, tom qab ntawd 1 rub down. nws kuj tsis tshua ruaj khov.

Spread Tow thiab Standard Tow

        Lub unidirectional carbon fiber tsis muaj dabtsi yog khoov lub xeev thiab muaj peev xwm dais lub zog zoo. Cov ntaub woven yuav tsum tau khoov mus rau hauv lub orthogonal kev taw qhia, thiab lub zog yuav poob zoo heev. Yog li thaum cov hlua fiber ntau yog woven nce thiab nqis los ua ib daim ntaub, lub zog raug txo vim yog crimps hauv cov cab. Thaum koj nce tus naj npawb ntawm cov cab hauv tus qauv cab los ntawm 3k mus rau 6k, tus cab tau loj dua (thicker) thiab lub kaum sab xis yuav loj dua. Ib txoj hauv kev kom tsis txhob muaj qhov no yog txhawm rau kis cov hlua mus rau hauv cov cab dav, qhov no yog hu ua kis kab mob, thiab cov ntaub uas tshwm sim kuj hu ua kis tau, uas muaj ntau yam txiaj ntsig.

        Lub kaum sab xis ntawm txoj hlua khi yog me dua li lub kaum sab xis ntawm txoj hlua khi ntawm tus qauv cab, yog li txo qhov kev sib tw los ntawm kev ua kom lub smoothness. Cov kaum sab xis me me yuav ua rau muaj zog dua. Cov ntaub ntawv sib kis tau yooj yim dua rau kev ua haujlwm nrog ntau dua li cov ntaub ntawv unidirectional thiab tseem muaj lub zog zoo fiber ntau tensile.

Unidirectional ntaub 

         Unidirectional daim ntaub tseem hu ua UD daim ntaub hauv kev lag luam. Raws li lub npe qhia, uni txhais tau tias ib qho, thiab tag nrho cov fibers yog taw qhia tib yam. Qhov no muab unidirectional (UD) fabrics ib co siab zog zoo. UD fabrics tsis yog woven fabrics, tsis muaj crimped interwoven tows. Tsuas yog cov kev taw qhia ua ntu zus fibers tuaj yeem ua kom muaj zog thiab nruj. Lwm qhov txiaj ntsig yog qhov muaj peev xwm los tswj cov khoom siv zog los ntawm kev kho lub kaum sab xis thiab ply ratio. Lub tsheb kauj vab thav duab siv cov ntaub unidirectional los txhim kho cov qauv layup los kho kev ua tau zoo yog qhov piv txwv zoo. Lub thav duab yuav tsum tswj kom nruj thiab nruj nyob rau hauv lub hauv qab bracket cheeb tsam kom hloov tus neeg caij lub hwj chim rau lub log, tab sis tus ncej kuj yuav tsum muaj ib co yooj. Nrog unidirectional daim ntaub, koj tuaj yeem xaiv qhov kev taw qhia meej ntawm cov pa roj carbon fiber ntau kom tau lub zog koj xav tau.

         Ib qho tsis zoo ntawm daim ntaub unidirectional yog qhov tsis zoo maneuverability. Unidirectional ntaub zoo li yooj yim unravel thaum lub sij hawm layup vim nws tsis muaj interwoven fibers los tuav nws ua ke. Yog tias cov fibers tsis raug muab tso kom raug, nws yuav luag tsis yooj yim sua kom reposition lawv kom raug dua. Unidirectional daim ntaub txiav tuaj yeem ua rau muaj teeb meem. Yog hais tias cov fibers raug rub mus rau hauv ib qho chaw ntawm kev txiav, cov xoob fibers yuav raug rub mus rau hauv cov ntaub. Feem ntau, yog cov ntaub unidirectional raug xaiv rau layup, tiaj, twill, thiab satin weave fabrics yog siv rau thawj thiab zaum kawg khaubncaws sab nraud povtseg los pab txhim kho processability thiab ib feem durability. Hauv nruab nrab txheej, ib daim ntaub unidirectional yog siv los tswj lub zog ntawm tag nrho ib feem
