1.Kev faib tawm ntawm Aramid Fibers
Cov fibers Aramid muaj peev xwm muab faib ua ob hom tseem ceeb raws li lawv cov qauv tshuaj sib txawv: ib hom yog tus cwj pwm los ntawm kev tiv taus cua sov, nplaim taws retardant meso-aramid, hu ua poly (p-toluene-m-toluoyl-m-toluamide), luv luv li PMTA, hu ua Nomex hauv Tebchaws Meskas, thiab Aramid 1313 hauv Suav teb; thiab lwm hom yog tus cwj pwm los ntawm lub zog siab, siab elasticity modulus, thiab tiv taus cua sov, hu ua poly (p-phenylene terephthalamide), luv luv li PPTA, hu ua Kevlar hauv Tebchaws Meskas, Technora hauv Nyiv, Twaron hauv Netherlands, Tevlon hauv Lavxias, thiab Tevlon hauv Suav teb. P-phenylenediamine, luv luv li PPTA, lub npe lag luam ntawm Tebchaws Meskas rau Kevlar, Nyiv rau Technora, Netherlands rau Twaron, Lavxias rau Tevlon, Suav teb hu ua aramid 1414.

Cov fiber aramidyog ib hom fiber uas tiv taus kub thiab txias, muaj zog thiab ywj siab, ob qho tib si cov khoom siv kho tshuab ntawm cov fiber inorganic thiab cov fiber organic, kev ua haujlwm zoo, qhov ceev thiab cov polyester fiber zoo sib xws. Tib lub sijhawm kuj muaj kev tiv thaiv tshuaj lom neeg zoo heev, tiv thaiv hluav taws xob, tiv thaiv kev qaug zog, ruaj khov thiab lwm yam khoom zoo thiab roj hmab resin nrog qee yam khoom nplaum. Tam sim no cov khoom muaj ob hom pulp thiab fiber. Ua aerospace, roj hmab, kev lag luam resin, khoom siv hluav taws xob thiab hluav taws xob, kev thauj mus los, khoom siv kis las thiab kev tsim kho pej xeem thiab lwm qhov chaw ntawm cov ntaub ntawv tshiab. Tshwj xeeb tshaj yog nrog aramid fiber npaj cov ntaub ntawv ua tau zoo aramid ntawv sib xyaw tuaj yeem siv dav ua cov ntaub ntawv rwb thaiv tsev hluav taws xob siab, cov laug cam luam tawm thiab cov ntaub ntawv tiv thaiv hluav taws xob electromagnetic thiab lwm yam khoom muaj nqis heev.

2. Aramid FiberKev hloov pauv ntawm lub cev
1414 fiber yog xim daj ci, 1313 fiber yog dawb ci. Feem ntau muaj ob hom fiber: luv luv fiber (lossis filament) thiab pulp fiber (lossis precipitation fiber). Filament feem ntau yog siv rau hauv textiles, roj hmab thiab lwm yam teb, kev lag luam ntawv siv staple fiber thiab pulp fiber.
