Carbon Fiber Weaves: Lawv Yog Dab Tsi thiab Vim Li Cas Koj Yuav Tsum Siv Lawv

Yog tias koj tau xav paub tias yog vim li cas ib daim ntawm carbon fiber yuav zoo li txawv dua lwm tus, koj tsis nyob ib leeg. Cov pa roj carbon fiber ntau los ntawm ntau qhov sib txawv, txhua qhov ua haujlwm sib txawv, thiab nws tsis yog kho kom zoo nkauj xwb.

 

Cov pa roj carbon fibers yog tsim los ntawm precursors xws li polyacrylonitrile (PAN) thiab rayon. Precursor fibers yog chemically kho, rhuab thiab ncab, ces carbonized los tsim high-strength fibers. Cov fibers no, los yog filaments, ces muab ntim ua ke los tsim cov cab, uas tau txheeb xyuas los ntawm cov pa roj carbon filaments lawv muaj. Cov chav kawm towing feem ntau yog 3k, 6k, 12k thiab 15k. "k" txhais tau tias ib txhiab, yog li 3k cab yog ua los ntawm 3, 000 carbon filaments. Tus qauv 3k cab feem ntau yog 0.125 "dav, yog li ntim cov fiber ntau rau hauv qhov chaw me me. A 6k cab muaj 6, 000 carbon filaments, 12k cab muaj 12,{{16 } } carbon filaments, thiab lwm yam. Muaj ntau lub zog fibers uas tau ntim ua ke yog qhov ua rau carbon fiber ntau cov khoom muaj zog.

Woven carbon fiber ntau
Cov pa roj carbon fiber ntau feem ntau tuaj rau hauv daim ntawv ntawm cov ntaub npuag, uas ua rau nws yooj yim dua rau kev ua haujlwm nrog thiab, nyob ntawm daim ntawv thov, tuaj yeem muab cov qauv tsim muaj zog ntxiv. Yog li ntawd, carbon fiber fabrics tuaj nyob rau hauv ntau yam sib txawv weaves. Feem ntau yog cov khoom, twill, thiab ribbon satin, thiab peb mam li saib txhua yam ntxiv.

dawb weave
Lub tiaj-weave carbon fiber panels tshwm symmetrical, nrog ib tug me me checkerboard tsos. Nyob rau hauv cov ntaub ntawv no, cov hlua yog woven nyob rau hauv ib tug over/under pattern. Qhov sib nrug luv luv ntawm cov weaves muab lub tiaj weave ib qib siab ntawm kev ruaj ntseg. Fabric stability yog lub peev xwm ntawm cov ntaub los tuav nws lub kaum sab xis thiab fiber ntau orientation. Vim tias qhov kev ruaj ntseg siab no, cov ntaub qhwv dawb tsis tshua haum rau cov txheej txheem contoured, nws yuav tsis hloov pauv raws li qee qhov sib txawv. Feem ntau hais lus, tiaj weave yog tsim rau cov ntawv tiaj tus, cov kav dej thiab ob sab nkhaus.

Ib qho tsis zoo ntawm cov qauv weave no yog ntxhib crimp (lub kaum sab xis ntawm cov fibers ua thaum weaving, saib hauv qab) hauv cov cab vim qhov luv luv ntawm interweaves. Rough crimps tsim muaj kev ntxhov siab uas tuaj yeem ua rau lub cev tsis muaj zog thaum lub sijhawm.

Twill weave
Twill ua tus choj ntawm lub tiaj weave thiab satin weave peb mam li tham ntxiv. Twill yog hloov tau txaus los tsim cov contours nyuaj thiab zoo dua ntawm kev tswj cov ntaub ruaj khov dua eeb satin weave, tab sis tsis zoo li cov weave. Yog hais tias koj ua raws li ib tug cab nyob rau hauv twill, nws mus los ntawm ib tug tej yam nab npawb ntawm cov cab thiab ces los ntawm tib tus naj npawb ntawm cov cab. Cov qauv saum toj no / hauv qab tsim ib kab pheeb ces kaum zoo li lub taub hau hu ua "twill line". Qhov kev ncua deb ntawm txoj hlua khi ntev dua txhais tau tias tsawg dua crimping thiab tsis tshua muaj peev xwm muaj kev ntxhov siab piv rau ib qho yooj yim weave.

2 × 2 Tiav

4 × 4 Tiav

2 × 2 Twill yog qhov zoo tshaj plaws paub carbon fiber ntaub hauv kev lag luam. Nws yog siv rau hauv ntau daim ntawv thov kom zoo nkauj thiab kho kom zoo nkauj tab sis kuj muaj kev ua haujlwm zoo, nws muaj ob qho tib si formability thiab nruab nrab stability. Raws li lub npe ntawm 2 × 2 txhais tau tias, txhua tus cab yuav dhau los ntawm 2 tus cab thiab tom qab ntawd dhau 2 tus cab. Ib yam li ntawd, 4 × 4 twill yuav dhau 4 tus cab thiab tom qab ntawd 4 tus cab. Nws yog me ntsis formable tshaj 2 × 2 twill vim hais tias lub weave tsis nruj li, tab sis nws kuj tsis tshua ruaj khov.
