Carbon Fiber 101: Nkag siab txog Weaves thiab Fabrics

Cov pa roj carbon fiber feem ntau yog woven rau hauv ntaub tom qab tsim thiab loj. Cov txheej txheem tsim khoom pib los ntawm kev tsim cov pob khoom ntawm carbon fibers hu ua cab. Cov cab no raug ntsuas raws li cov fibers lossis filaments uas lawv muaj, feem ntau hu ua 3k, 6k, 12k, thiab 48k. Lub "k" sawv cev rau "txhiab," uas txhais tau hais tias 3k cab muaj 3, 000 carbon filaments. Txhua txoj hlua ntawm cov roj carbon fiber ntau tsuas yog kwv yees li 5-10 microns tuab, tab sis qhov loj ntawm cov pa roj carbon fiber ntau hauv qhov chaw sib cog ua kom cov khoom muaj zog txaus.

 

carbon fiber ntau
Spools ntawm carbon fiber yog woven rau hauv ntaub ntawm ib lub loom. Feem ntau cov weaves yog tiaj weave, twill weave thiab heddle weave.

dawb weave
Plain weave los yog 1x1 weave carbon fiber ntaub yog symmetrical thiab zoo li lub checkerboard. Cov cab yog woven nyob rau hauv ib qho dhau / hauv qab qauv, muab kev ruaj khov, nruj nreem fibers. Fabric stability yog hais txog lub peev xwm ntawm cov khoom siv los tswj nws txoj kev taw qhia fiber ntau thiab lub kaum sab xis. Vim nws cov ntaub ntawv siab ruaj khov, cov pa roj carbon fiber ntau tsis haum rau cov contours nyuaj vim nws tsis hloov pauv tshwj xeeb. Txawm li cas los xij, nws yooj yim dua los tuav thiab tsis ua rau cov ntaub deformation. Yog li ntawd, nws yog qhov zoo tagnrho rau cov ntawv tiaj tus, cov hlab thiab 2D nkhaus.

Crimp yog curvature ntawm tus neeg fibers nyob rau hauv lub weave, thiab cov pa roj carbon fiber ntaub ntaub muaj ib tug ntxhib crimp vim lub nruj interweaving ntawm lub filament strands. Nyob rau tib lub sijhawm, qhov hnyav curling no tsim cov ntsiab lus kev ntxhov siab uas ua rau cov chaw tsis muaj zog.

Twill weave

Twill weave, muaj xws li 2x2 lossis 4x4 qauv, yog hom carbon fiber ntau ntau. Nyob rau hauv ib tug 2x2 braid, txhua strand yog hla dhau ob strands thiab ces nyob rau hauv ob strands. Nws sawv rau qhov laj thawj, yog li ntawd, tias 4x4 braid muaj txhua tus cab hla plaub tus cab thiab tom qab ntawd plaub tus cab ntxiv. Qhov no tshaj / hauv qab weave tsim ib qho txawv kab pheeb ces kaum. Qhov kev ncua deb ntawm interlacing strands nyob rau hauv ib tug twill weave yog ntev dua nyob rau hauv ib tug dawb weave. Yog li ntawd, tsawg curling tshwm sim, txo txoj hauv kev tsim cov ntsiab lus kev ntxhov siab.

Twill weave yog hloov tau thiab tuaj yeem tsim cov contours nyuaj thaum tseem muaj kev ruaj ntseg zoo. Nws yuav tsum tau ua tib zoo saib xyuas ntau dua li cov weave dawb kom tsis txhob muaj cov ntaub so ntswg ntau deformation. Lub 4x4 weave yog yooj yim rau kev tsim dua 2x2 weave, tab sis cov ntaub kuj tsis tshua ruaj khov.

Horse harness satin weave

Satin weave tau siv ntau txhiab xyoo los muab cov ntaub lo lo ntxhuav zoo nkauj drape thaum ua cov ntaub du thiab seamless. Thaum siv cov pa roj carbon fiber ntau, satin weaves tuaj yeem yooj yim tsim cov contours. Pom tseeb, qhov no txhais tau hais tias kev ruaj ntseg ntawm satin weave kuj qis dua lwm cov weaves.

Feem ntau satin weaves yog plaub-heddle satin (4HS), tsib-heddle satin (5HS) thiab yim-heddle satin (8HS). Tus lej no sawv cev rau tag nrho cov cab uas tau dhau los thiab dhau mus. Piv txwv li, 4HS cov ntaub so ntswg muaj peb lub filament strands hla nws thiab tom qab ntawd ib qho filament strand hla nws. Nrog rau 5HS, plaub tus cab hla thiab tom qab ntawd ib qho hauv qab, thaum nrog 8HS xya tus cab hla thiab tom qab ntawd ib qho hauv qab. Qhov siab dua tus naj npawb satin weave, qhov zoo dua qhov formability, tab sis qhov phem dua qhov ruaj khov.

Lwm yam weaves
Muaj ntau ntau lwm txoj hauv kev siv los tsim cov ntaub ntawv carbon fiber. Cov no muaj xws li ntses braid, cab kis, braid, unidirectional braid thiab kev cai braid. Txhua lub weave muaj cov khoom tshwj xeeb uas ua rau nws zoo tagnrho rau siv hauv qee qhov qauv, tab sis tsis yog qhov kev xaiv zoo rau lwm tus. Muaj ntau yam uas yuav tsum tau xav txog thaum txiav txim siab uas carbon fiber braid yuav tsum tau siv los ua ib qho haujlwm tshwj xeeb. Cov yam ntxwv no muaj xws li lub zog, formability, stability thiab curl. Cov tuam txhab carbon fiber ntau yog cov kws paub txog cov ntaub ntawv twg yuav tsum tau siv rau tus qauv tsim.
