Ifayibha ye-Aramid ibizwa ngokuba yi-polybenzoylenediamine, kunye ne-carbon fiber, i-ultra-high molecular weight polyethylene fiber kunye ne-fiber ezintathu eziphambili zehlabathi ezisebenza kakhulu, ukuxinana okuncinci, amandla aphezulu, i-modulus ephezulu, ukumelana nobushushu obuphezulu, ukuxhathisa ukubola, ukugquma, isetyenziswa ngokubanzi zomkhosi, i-aerospace, izixhobo zombane, ezothutho, ulwakhiwo, unyango kunye nezinye iinkalo. Ifayibha ye-Aramid yifayibha yokwenziwa enuka kamnandi yepolyamide, eyenziwe ngepolymer engumtya wokwenziwa (ubuncinci i-85% ye-amide bond idityaniswe ngokuthe ngqo kumakhonkco amabini anevumba elimnandi) eyenziwe yi-amide bond edibanisa iringi enuka kamnandi (Ar-CONH-Ar). Ikhonkco eliphambili lenziwe ngeringi enuka kamnandi kunye ne-amide bond, kwaye isakhi seringi esinevumba elimnandi siqinile. Ikhonkco lepolymer yoluliwe ukwenza isakhiwo esifana nentonga.
Kwangaxeshanye, ubume bomgca wekhonkco lemolekyuli lenza ukuba i-aramid fibre indawo yokusetyenziswa kweqondo ibephezulu, ngoko ke umthamo weyunithi unokwamkela ipolymer ngaphezulu, ngoko ke amandla aphezulu. Ngokwahlukileyo kwimixokelelwane ye-polymer eguquguqukayo eqhelekileyo, ikhonkco eliphambili le-para-aramid fiber liqulunqwe ikakhulu yintonga efana ne-molecular structure eyenziwe yiring ye-benzene. Ngenxa yobukho beringi enkulu ye-benzene edibeneyo, icandelo lekhonkco lemolekyuli kunzima ukujikeleza ngaphakathi, ngoko ke libonisa umgca oqinileyo.
