1.Ukuhlukaniswa Kwezintambo Ze-Aramid
Imicu ye-Aramid ingahlukaniswa ngezinhlobo ezimbili eziyinhloko ngokwezakhiwo zayo zamakhemikhali ezahlukene: uhlobo olulodwa lubonakala ngokumelana nokushisa, i-meso-aramid egcina ilangabi, eyaziwa ngokuthi i-poly(p-toluene-m-toluoyl-m-toluamide), efingqiwe ngokuthi i-PMTA, eyaziwa ngokuthi i-Nomex e-US, kanye ne-Aramid 1313 eShayina; kanti olunye uhlobo lubonakala ngokuqina okuphezulu, i-elasticity modulus, kanye nokumelana nokushisa, eyaziwa ngokuthi i-poly(p-phenylene terephthalamide), efingqiwe ngokuthi i-PPTA, eyaziwa ngokuthi i-Kevlar e-US, i-Technora eJapan, i-Twaron eNetherlands, i-Tevlon eRussia, kanye ne-Tevlon eShayina. I-P-phenylenediamine, efingqiwe ngokuthi i-PPTA, igama lokuhweba le-United States le-Kevlar, iJapan le-Technora, iNetherlands le-Twaron, iRussia le-Tevlon, iShayina elibizwa ngokuthi i-aramid 1414.

I-Aramid fiberiyimodeli yezinhlobo zemicu ekwazi ukumelana nokushisa okuphezulu, enamandla aphezulu, nenokunwebeka okuphezulu, kokubili izakhiwo zemishini zemicu engaphili kanye nemicu ephilayo, ukusebenza kokucubungula, ubuningi kanye nemicu ye-polyester kuyalingana. Ngesikhathi esifanayo futhi inokumelana okuhle kwamakhemikhali, ukumelana nemisebe, ukumelana nokukhathala, ukuzinza kobukhulu kanye nezinye izakhiwo ezinhle kanye ne-resin yerabha enezakhiwo ezithile zokunamathela. Njengamanje umkhiqizo unezinhlobo ezimbili ze-pulp kanye ne-fiber. Iba yi-aerospace, irabha, imboni ye-resin, imishini kagesi neyegesi, ezokuthutha, imishini yezemidlalo kanye nokwakhiwa kwezakhiwo kanye nezinye izindawo zezinto ezintsha. Ikakhulukazi ngokulungiswa kwe-fiber ye-aramid, izinto ezihlanganisiwe zephepha le-aramid ezisebenza kahle zingasetshenziswa kabanzi njengezinto zokufakelwa kukagesi ezisezingeni eliphezulu, amabhodi wesekethe aphrintiwe kanye nezinto zokuvikela amagagasi kagesi kanye nezinye izinto ezihlonishwa kakhulu.

2. I-Aramid FiberI-Mofology
I-fiber ka-1414 iphuzi ngokugqamile, i-fiber ka-1313 imhlophe ngokugqamile. Ngokulandelana, kunezinhlobo ezimbili ze-fiber nge-fiber emfushane (noma i-filament) kanye ne-pulp fiber (noma i-precipitation fiber). I-Filament isetshenziswa kakhulu ezindwangu, enjolobeni nakwamanye amasimu, embonini yephepha kusetshenziswa i-staple fiber kanye ne-pulp fiber.
