1.Ukuhlelwa kweeFiber zeAramid
Iifayibha ze-Aramid zinokwahlulwa zibe ziindidi ezimbini eziphambili ngokwezakhiwo zazo zeekhemikhali ezahlukeneyo: olunye uhlobo lubonakaliswa ngokumelana nobushushu, i-meso-aramid i-flame retardant, eyaziwa ngokuba yi-poly (p-toluene-m-toluoyl-m-toluamide), efinyeziweyo njenge-PMTA, eyaziwa ngokuba yi-Nomex e-US, kunye ne-Aramid 1313 e-China; kunye nolunye uhlobo lubonakaliswa ngokuqina okuphezulu, imodyuli ephezulu yokuqina, kunye nokumelana nobushushu, eyaziwa ngokuba yipoly(p-phenylene terephthalamide), ifinyeziwe njengePPTA, eyaziwa ngokuba yiKevlar eUS, iTechnora eJapan, iTwaron eNetherlands, iTevlon eRussia, kunye neTevlon eTshayina. I-P-phenylenediamine, efinyeziweyo njenge-PPTA, igama lokurhweba lase-United States le-Kevlar, i-Japan ye-Technora, i-Netherlands ye-Twaron, i-Russia ye-Tevlon, i-China ebizwa ngokuba yi-aramid 1414.

Ifayibha yeAramidi-high-temperature-resistant, high-high-high, high-elastic model type of fibers, zombini iipropathi ze-mechanical ze-inorganic fibers kunye ne-organic fibers, ukusebenza kokucubungula, ukuxinana kunye ne-polyester fibers zifaniswa. Kwangaxeshanye nayo inokumelana nekhemikhali ebalaseleyo, ukuxhathisa kwimitha, ukumelana nokudinwa, ukuzinza kwedimensional kunye nezinye iipropathi ezilungileyo kunye nerabha yerabha eneempawu ezithile zokuncamathelisa. Okwangoku imveliso ineendlela ezimbini zepulp kunye nefiber. Yiba yi-aerospace, irabha, ishishini le-resin, izixhobo zombane kunye nezombane, ezothutho, izixhobo zemidlalo kunye nokwakhiwa koluntu kunye neminye imimandla yezinto ezintsha. Ngokukodwa ngokulungiswa kwefayibha ye-aramid yezixhobo eziphezulu ze-aramid ezihlanganisiweyo zephepha zinokusetyenziswa ngokubanzi njengezinto zokufakelwa kombane ezikumgangatho ophezulu, iibhodi zesekethe eziprintiweyo kunye nezixhobo zokukhusela amaza ombane kunye nezinye ezithathelwa ingqalelo kakhulu.

2. IFayibha yeAramidImorphology
I-fiber ye-1414 igqamile tyheli, i-1313 fiber imhlophe qhwa. Ngokulandelelana kunye neentsinga ezimfutshane (okanye i-filament) kunye ne-pulp fiber (okanye i-precipitation fiber) iifom ezimbini zefiber. I-Filament isetyenziswa ikakhulu kumalaphu, irabha kunye namanye amasimi, ishishini lamaphepha lisebenzisa i-staple fiber kunye ne-pulp fiber.
