Hom iav Fiber Mats thiab Fabrics

iav Fiber Mats

1.Chopped Strand Mat (CSM)iav fiber ntau rov(qee zaum kuj nruam roving) yog txiav mus rau hauv 50 hli ntev, randomly tab sis uniformly nteg rau ib tug conveyor mesh siv. Tom qab ntawd, ib qho emulsion binder yog siv, los yog hmoov binder yog plua plav rau, thiab cov khoom yog rhuab thiab kho kom tsim cov tws strand lev. CSM feem ntau yog siv rau hauv tes nteg, ua vaj huam sib luag txuas ntxiv, sib txuam tuag molding, thiab SMC (Sheet Molding Compound) cov txheej txheem. Cov kev cai zoo rau CSM suav nrog:

• Uniform cheeb tsam hnyav thoob plaws qhov dav.
• Uniform faib ntawm tws strands ntawm lub lev nto tsis muaj voids loj, thiab uniform binder faib.
• Nruab nrab qhuav lev zog.
• Zoo heev resin wetting thiab nkag tau zoo.

2.Nruam Filament Mat (CFM)Nruam iav fiber ntau filaments tsim thaum lub sij hawm kev kos duab los yog unwound los ntawm roving tej pob khoom yog nteg nyob rau hauv ib daim duab-yim qauv ntawm ib tug tsis tu ncua txav mesh siv thiab bonded nrog ib tug hmoov binder. Txij li cov fibers hauv CFM txuas ntxiv mus, lawv muab kev txhawb zog zoo dua rau cov ntaub ntawv sib xyaw dua li CSM. Nws yog tsuas yog siv rau hauv pultrusion, RTM (Resin Transfer Molding), siab lub hnab molding, thiab GMT (Glass Mat Reinforced Thermoplastics) txheej txheem.

3.Surfacing MatFRP (Fiber Reinforced Plastic) cov khoom lag luam feem ntau xav tau cov txheej txheej txheej txheej, uas feem ntau ua tiav siv cov iav nruab nrab-alkali iav (C-iav) surfacing lev. Raws li cov lev no yog tsim los ntawm C-iav, nws muab FRP nrog tshuaj tiv thaiv, tshwj xeeb tshaj yog acid tsis kam. Tsis tas li ntawd, vim nws qhov thinness thiab finer fiber ntau txoj kab uas hla, nws muaj peev xwm nqus tau ntau resin los tsim ib tug resin-nplua nuj txheej, npog cov kev ntxhib los mos ntawm iav fiber reinforcing cov ntaub ntawv (xws li woven roving) thiab ua hauj lwm raws li ib tug nto.

4.Koob MatTau categorized rau Chopped Fiber Needled Mat thiab Nruam Filament Needled Mat.

•  Chopped Fiber Needled Matyog tsim los ntawm chopping iav fiber roving rau hauv 50 hli ntev, randomly nteg lawv nyob rau hauv ib tug substrate yav tas los muab tso rau ib tug conveyor siv, thiab ces needling nws nrog barbed koob. Cov koob thawb cov tws fibers mus rau hauv lub substrate, thiab cov barbs kuj coj ib co fibers, tsim ib tug peb-dimensional qauv. Lub substrate siv yuav yog ib tug xoob woven ntaub ntawm iav los yog lwm yam fibers. Hom koob lev no muaj qhov zoo li kev ntxhib los mos. Nws cov khoom siv tseem ceeb suav nrog cov ntaub ntawv thermal thiab acoustic rwb thaiv tsev, cov ntaub ntawv hauv ob sab phlu, thiab cov ntaub ntawv pom. Nws kuj tseem tuaj yeem siv rau hauv FRP ntau lawm, tab sis qhov tshwm sim FRP muaj zog qis dua thiab txwv daim ntawv thov.
•  Nruam Filament Needled Matyog tsim los ntawm randomly ntuav nruam iav fiber ntau filaments mus rau ib tug nruam mesh siv siv ib tug filament kis ntaus ntawv, ua raws li los ntawm needling nrog ib rab koob board los ua ib tug lev nrog ib tug interwoven peb-dimensional fiber qauv. Cov lev no feem ntau yog siv rau hauv kev tsim cov iav fiber reinforced thermoplastic stampable nplooj ntawv.

5.Stitched MatTxiav iav fibers xws li 50mm mus rau 60cm nyob rau hauv ntev yuav stitched ua ke nrog ib tug stitching tshuab los tsim ib tug tws fiber lev los yog ib tug ntev fiber lev. Tus qub tuaj yeem hloov cov ntaub ntawv sib khi-txheej txheem CSM hauv qee daim ntawv thov, thiab tom kawg tuaj yeem, rau qee qhov, hloov CFM. Lawv qhov zoo sib xws yog qhov tsis muaj cov ntawv khi, tsis txhob muaj kuab paug thaum lub sijhawm tsim khoom, zoo resin impregnation kev ua tau zoo, thiab tus nqi qis dua.

Iav Fiber Fabrics

Cov hauv qab no qhia ntau yam iav fiber ntau woven los ntawmiav fiber ntau yarns.

1. Cov ntaub iaviav ntaub uas tsim nyob rau hauv Tuam Tshoj yog muab faib ua alkali-dawb (E-iav) thiab nruab nrab-alkali (C-iav) hom; Feem ntau cov khoom siv txawv teb chaws siv E-GLASS alkali-dawb iav ntaub. Cov ntaub iav feem ntau yog siv los tsim ntau yam hluav taws xob insulating laminates, luam tawm Circuit Court boards, lub cev lub tsheb, lub tank cia, nkoj, pwm, thiab lwm yam. Medium-alkali iav ntaub yog tsuas yog siv los tsim cov yas-coated ntim fabrics thiab rau corrosion-resistant daim ntaub ntawv. Cov yam ntxwv ntawm cov ntaub yog txiav txim siab los ntawm cov khoom siv fiber ntau, warp thiab weft ntom, xov paj, thiab cov qauv weave. Warp thiab weft ntom yog txiav txim los ntawm cov qauv xov paj thiab weave qauv. Kev sib xyaw ua ke ntawm Warp thiab Weft Density thiab Xov Xwm Xov Vaj Tsev txiav txim siab cov khoom siv lub cev ntawm cov ntaub, xws li qhov hnyav, tuab, thiab rhuav lub zog. Muaj tsib yam qauv yooj yim weave: dawb (zoo ib yam li woven roving), twill (feem ntau ± 45 °), satin (zoo ib yam li unidirectional ntaub), leno (lub ntsiab weave rau iav fiber mesh), thiab matts (zoo ib yam li oxford ntaub).

2.iav Fiber daim kab xevMuab faib ua woven-ntug daim kab xev (selvage edge) thiab non-woven-edge daim kab xev (frayed edge). Lub ntsiab weave qauv yog dawb. Alkali-dawb iav fiber ntau daim kab xev feem ntau yog siv los tsim cov khoom siv hluav taws xob uas xav tau lub zog siab thiab zoo dielectric zog.

3.Iav Fiber Unidirectional Npuag

•  Unidirectional Warp Npuagyog plaub-txoj hlua tawg satin lossis ntev-ncej satin weave npuag woven nrog ntxhib warp yarns thiab zoo weft yarns. Nws tus yam ntxwv yog siab zog feem ntau nyob rau hauv warp kev taw qhia (0 °).
• Kuj muajIav Fiber Unidirectional Weft Fabric, muaj nyob rau hauv ob qho tib si warp-knitted thiab woven hom. Nws yog tus cwj pwm los ntawm cov xov paj ntxhib thiab cov xov paj zoo, nrog rau cov iav fiber ntau cov xov paj feem ntau yog nyob rau hauv cov kev taw qhia weft, muab lub zog siab hauv peb cov kev taw qhia weft (90 °).

4.Iav Fiber 3D Npuag (Stereoscopic Fabric)3D fabrics yog txheeb ze rau cov ntaub ntawv. Lawv cov yam ntxwv nta tau hloov zuj zus los ntawm ib-seem thiab ob-dimensional mus rau peb-dimensional, muab cov ntaub ntawv sib xyaw ntxiv los ntawm lawv txoj kev ncaj ncees thiab kev sib haum xeeb, txhim kho lub zog interlaminar shear thiab tiv thaiv kev puas tsuaj ntawm cov khoom sib xyaw. Lawv tau tsim los ua kom tau raws li cov kev xav tau tshwj xeeb ntawm aerospace, aviation, riam phom, thiab marine sectors, thiab tam sim no lawv daim ntawv thov tau nthuav dav suav nrog tsheb, khoom ua si, thiab khoom siv kho mob. Muaj tsib pawg tseem ceeb: woven 3D fabrics, knitted 3D fabrics, orthogonal thiab non-orthogonal non-crimp 3D fabrics, 3D braided fabrics, thiab lwm yam ntaub ntawv ntawm 3D fabrics. Cov duab ntawm 3D fabrics muaj xws li thaiv, columnar, tubular, hollow truncated cone, thiab sib txawv-thickness irregular cross-sections.

5.Glass Fiber Preform Npuag (zoo li ntaub)Cov duab ntawm preform fabrics yog heev zoo ib yam li cov duab ntawm cov khoom lawv yog npaj los txhawb, thiab lawv yuav tsum tau woven rau nplooj siab looms. Symmetrical shaped fabrics muaj xws li: spherical caps, cones, kaus mom, dumbbell-shaped fabrics, thiab lwm yam. Asymmetrical shapes zoo li lub thawv thiab lub nkoj hulls kuj raug tsim.

6.Iav Fiber Core Fabric (Thickness Stitching Fabric)Cov ntaub tseem ceeb muaj ob txheej txheej ntawm cov ntaub sib txuas los ntawm cov kab ntsug ntsug ntev. Nws cov duab hla ntu tuaj yeem yog daim duab peb sab, duab plaub, lossis honeycomb.

7.Iav Fiber Stitch-Bonded Fabric (Knitted Mat lossis Woven Mat)Nws txawv ntawm cov ntaub zoo tib yam thiab los ntawm kev nkag siab li niaj zaus ntawm lev. Cov feem ntau raug stitch-bonded ntaub yog tsim los ntawm overlaying ib txheej ntawm warp yarn thiab ib txheej ntawm weft yarn, thiab ces stitching lawv ua ke los ua ib tug ntaub. Qhov zoo ntawm stitch-bonded fabrics muaj xws li:

• Nws tuaj yeem ua rau lub zog tensile qhov kawg, lub zog tiv thaiv delamination nyob rau hauv nro, thiab flexural zog ntawm FRP laminates.
• Nws txo qhov hnyav ntawmFRP khoom.
• Lub tiaj tiaj ua rau FRP nto smoother.
• Nws ua kom yooj yim rau kev ua haujlwm ntawm tes thiab txhim kho cov khoom tsim tawm. Cov khoom siv txhawb zog no tuaj yeem hloov CFM hauv pultruded FRP thiab RTM, thiab tuaj yeem hloov woven roving hauv centrifugal cam khwb cia FRP yeeb nkab ntau lawm.
