1.Fa'avasegaina o Aramid Fibers
E mafai ona vaevaeina filo Aramid i ni ituaiga autu se lua e tusa ai ma o latou fausaga vailaʻau eseese: o le tasi ituaiga e faʻaalia i le vevela, faʻamaʻi afi meso-aramid, e taʻua o le poly(p-toluene-m-toluoyl-m-toluamide), faʻapuʻupuʻu e pei o le PMTA, e taʻua o Nomex i le US, ma Aramid 1313 i Saina; ma o le isi ituaiga o loʻo faʻaalia i le maualuga-malosi, maualuga le elasticity modulus, ma le vevela, e taʻua o le poly(p-phenylene terephthalamide), faʻapuʻupuʻu o le PPTA, e taʻua o Kevlar i le US, Technora i Iapani, Twaron i Netherlands, Tevlon i Rusia, ma Tevlon i Saina. P-phenylenediamine, fa'apu'upu'u o le PPTA, o le igoa tau fefa'ataua'iga a le Iunaite Setete mo Kevlar, Iapani mo Technora, Netherlands mo Twaron, Rusia mo Tevlon, Saina e ta'ua o le aramid 1414.

Aramid fibero se maualuga-vevela-teteena, maualuga-malosi, maualuga-elastic faʻataʻitaʻiga ituaiga o alava, o mea faʻainisinia uma o alava inorganic ma alava organic, gaioiga gaioiga, density ma alava polyester e faʻatusatusa. I le taimi lava e tasi o loʻo i ai foʻi le sili atu o vailaʻau faʻamaʻi, faʻamalositino tetee, faʻavaivai vaivai, tulaga mautu ma isi mea lelei ma le paʻu paʻu ma nisi mea faʻapipiʻi. I le taimi nei o le oloa e lua ituaiga o pulu ma fiber. Avea aerospace, paʻu, resin alamanuia, mea faaeletonika ma eletise, felauaiga, taaloga meafaigaluega ma le fausiaina o tagata ma isi vaega o mea fou. Aemaise lava i le saunia o le alava aramid o mea fa'apipi'i pepa aramid maualuga e mafai ona fa'aaogaina lautele e pei o mea fa'amalo eletise maualuga, laupapa fa'asalalau lolomi ma mea e puipuia ai galu electromagnetic ma isi mea e sili ona taua.

2. Aramid FiberMorphology
1414 alava lanu samasama susulu, 1313 alava lanu pa'epa'e. E fa'atatau i alava pupu'u (po'o filament) ma alava pulupulu (po'o alava timuga) e lua ituaiga alava. O le filament e masani ona faʻaaogaina i ie, paʻu ma isi fanua, o le alamanuia pepa e faʻaaogaina ai le alava ma le pulupulu.
