1. Aramid fiber ntau untwisted roving ntaub, feem ntau nrog aramid 1414 filament, untwisted roving yog ua los ntawm parallel precursor yarn los yog parallel monofilament bundle. Lub monofilament txoj kab uas hla ntawm aramid fibers siv nyob rau hauv zus tau tej cov roving txawv ntawm 5 ~ 15μm. Tus naj npawb ntawm untwisted rovings yog li ntawm 100 txog 8000 (tex). Tsis-twisted roving tuaj yeem siv ncaj qha rau hauv qee cov txheej txheem molding txoj kev, xws li cov ntaub ntawv tshwj xeeb, ntawv prepreg, yeeb nkab winding, profile pultrusion thiab lwm yam txheej txheem, cov xov paj uas tsis yog-twisted vim nws tsis sib xws, tuaj yeem woven rau hauv untwisted roving thiab tshwj xeeb. aramid fabrics, siv nyob rau hauv aerospace, tiv thaiv, tub rog thiab lwm yam kev lag luam tshwj xeeb.
Feem ntau tsis tshua muaj grammage aramid daim ntaub dawb ntaub, ib qho ntawm cov mos txwv ntaub; Aramid non-woven daim ntaub, uas yog, UD mos mos ntaub; Aramid unidirectional daim ntaub, siv nyob rau hauv lub sij hawm uas yuav tsum tau siab zog nyob rau hauv ib qho kev taw qhia ntawm 0 degrees nyob rau hauv lub warp kev taw qhia los yog 90 degrees nyob rau hauv lub weft kev taw qhia, xws li structural kho, seismic reinforcement, lub tsev reinforcement, choj reinforcement, thiab lwm yam.; Cov ntaub aramid zoo nkauj kuj tuaj yeem ua rau hauv cov ntaub aramid twill thiab cov ntaub aramid xim.
2. Aramid non-woven npuag, muaj ntaub ntawv, aramid ntawv, siv rau rwb thaiv tsev thiab kub preservation
Aramid fiber ntau twisted zoo gauze, aramid ntaub, aramid ntaub, mas nrog aramid 1313 los yog ib tug me me ntawm 1414 staple fiber.
(1) Aramid fiber ntau twisted zoo gauze feem ntau yog hais txog ntau yam ntaub woven tom qab twisting nrog aramid 1313 los yog ib tug me me ntawm 1414 staple fiber yarn. Feem ntau siv nyob rau hauv hluav taws kub retardant thiab lwm yam teb. Cov yam ntxwv ntawm cov ntaub yog txiav txim siab los ntawm cov khoom fiber ntau, warp thiab weft ntom, xov paj qauv thiab kev ntxhib los mos. Lub warp thiab weft ntom yog txiav txim los ntawm cov xov paj qauv thiab kev ntxhib los mos. Lub warp thiab weft ceev ntxiv rau cov xov paj qauv txiav txim siab lub cev lub zog ntawm cov ntaub, xws li qhov hnyav, thickness thiab tawg lub zog. Muaj tsib qhov yooj yim weaves: tiaj, twill, satin, ribbed thiab lev.
(2) Aramid twisted webbing tau muab faib ua daim kab xev webbing (lub teeb ntug siv) thiab tsis-woven ntug siv (raws li siv tawv), thiab lub ntsiab weaving txoj kev yog dawb weave. Nws yog siv nyob rau hauv kev tsim cov high-zog, dielectric qhov chaw ntawm cov khoom siv hluav taws xob thiab tsheb hoses.
(3) Aramid qaum ntaub, uas yog, twisted aramid unidirectional ntaub impregnated, uas yog yus muaj los ntawm siab zog nyob rau hauv kev coj ntawm warp 0 degrees los yog weft yarn 90 degrees. Ntawm lawv, warp unidirectional ntaub yog plaub-warp tawg satin los yog ntev-ncej satin ntaub woven los ntawm roving warp thiab zoo weft yarn, uas yog siv nyob rau hauv aircraft log tsheb thiab high-qib tsheb log tsheb.
(4) Peb-dimensional ntaub peb-dimensional npuag yog txheeb ze rau cov ntaub tiaj tus, nws cov yam ntxwv ntawm cov qauv tau tsim los ntawm ib-dimensional ob-dimensional mus rau peb-seem, kom cov khoom sib xyaw nrog qhov no raws li qhov kev txhawb zog muaj kev ncaj ncees thiab profile, thiab zoo heev txhim kho lub interlaminar shear zog thiab puas kam rau ua ntawm cov khoom sib xyaw. Nws yog tsim los nrog cov kev xav tau tshwj xeeb ntawm aerospace, aviation, riam phom, nkoj thiab lwm lub tuam tsev, thiab nws daim ntawv thov tau txuas ntxiv mus rau tsheb, khoom siv kis las, khoom siv kho mob thiab lwm lub tuam tsev. Muaj tsib pawg tseem ceeb: woven peb-dimensional fabrics, knitted peb-dimensional fabrics, orthogonal thiab non-orthogonal non-woven peb-dimensional fabrics, peb-dimensional woven fabrics thiab lwm yam ntaub ntawv ntawm peb-dimensional fabrics. Cov duab ntawm peb-dimensional fabrics muaj xws li thaiv, columnar, tubular, hollow truncated cone thiab txawv txawv thickness tshwj xeeb-zoo li tus ntoo khaub lig-section.
(5) Cov ntaub tshwj xeeb-puab Cov duab ntawm cov ntaub tshwj xeeb zoo li zoo ib yam li cov duab ntawm tsab xov xwm nws yuav tsum tau kho kom zoo, thiab yuav tsum tau woven rau ntawm ib qho tshwj xeeb loom. Symmetrical zoo li tus tshwj xeeb-puab ntaub muaj xws li: puag ncig npog, cones, lub kaus mom, dumbbell-shaped fabrics, thiab lwm yam, thiab tseem tuaj yeem ua rau hauv cov duab asymmetrical xws li lub thawv thiab hulls.
(6) Grooved core fabric Grooved core fabric yog ib daim ntaub tsim los ntawm ob txheej ntawm cov ntaub uas sib luag, txuas nrog cov kab ntsug ntsug ntev, thiab nws cov duab ntoo khaub lig tuaj yeem yog daim duab peb sab lossis duab plaub.
(7) Kev xaws knitting tseem hu ua knitted xav lossis woven xav, uas txawv ntawm cov ntaub zoo tib yam thiab txawv ntawm cov ntaub hauv qhov kev xav ib txwm muaj. Qhov feem ntau yog sewing weave yog ib txheej ntawm warp yarn overlapped nrog ib txheej ntawm weft yarn, thiab warp yarn yog woven ua ke nrog lub weft yarn los ua ntaub.
3. Kev sib xyaw aramid daim ntaub
Ntawd yog, aramid xav, aramid untwisted roving ntaub thiab aramid untwisted roving, thiab lwm yam, yog ua ke nyob rau hauv ib qho kev txiav txim ntawm aramid composite ntaub.
