1.Fa'avasegaga o Alava Aramid
E mafai ona vaevaeina alava aramid i ni ituaiga autū se lua e tusa ai ma o latou fausaga fa'akemikolo eseese: o le tasi ituaiga e iloga i le tete'e atu i le vevela, o le meso-aramid e tete'e atu i le afi, e ta'ua o le poly(p-toluene-m-toluoyl-m-toluamide), e fa'apu'upu'u o le PMTA, e ta'ua o le Nomex i le US, ma le Aramid 1313 i Saina; ma le isi ituaiga e iloga i le malosi maualuga, le maualuga o le modulus elasticity, ma le tete'e atu i le vevela, e ta'ua o le poly(p-phenylene terephthalamide), e fa'apu'upu'u o le PPTA, e ta'ua o le Kevlar i le US, Technora i Iapani, Twaron i Netherlands, Tevlon i Rusia, ma Tevlon i Saina. O le P-phenylenediamine, e 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.

Alava aramidO se ituaiga faʻataʻitaʻiga e teteʻe atu i le vevela maualuga, malosi tele, ma e maualuga le faʻapipiʻiina o alava, e tutusa uma meatotino faʻainisinia o alava inorganic ma alava organic, faʻatinoga o le faʻagasologa, mafiafia ma alava polyester. I le taimi lava e tasi e iai foʻi le teteʻe lelei i vailaʻau, teteʻe atu i le radiation, teteʻe atu i le vaivai, mautu le fua ma isi meatotino lelei ma le resin paʻu ma nisi meatotino pipii. I le taimi nei, e lua ituaiga o le oloa o le pulp ma le alava. E avea ma aerospace, paʻu, alamanuia resin, mea eletise ma eletise, felauaiga, mea taʻaloga ma fausiaina o fale ma isi vaega o mea fou. Aemaise lava i le sauniuniga o alava aramid o mea tuʻufaʻatasi pepa aramid maualuga e mafai ona faʻaaogaina lautele o mea faʻavevela eletise maualuga, laupapa matagaluega lolomi ma mea puipuia galu eletise ma isi mea e sili ona lauiloa.

2. Alava AramidMorphology
1414 alava e samasama susulu, 1313 alava e paʻepaʻe susulu. E lua ituaiga alava e faʻaaogaina ai alava pupuu (poʻo le filament) ma alava pulp (poʻo le precipitation fiber). E masani ona faʻaaogaina le filament i ie, paʻu ma isi vaega, ma e faʻaaogaina foʻi le alava staple ma le alava pulp i le alamanuia pepa.
