Aramid CHIKWANGWANI amatchedwa polybenzoylenediamine, ndi mpweya CHIKWANGWANI, kopitilira muyeso-mkulu molekyulu kulemera polyethylene CHIKWANGWANI ndi atatu padziko lonse mkulu-ntchito CHIKWANGWANI, ndi kachulukidwe kakang'ono, mphamvu mkulu, modulus mkulu, kutentha kukana, dzimbiri kukana, kutchinjiriza, chimagwiritsidwa ntchito mu zankhondo, zakuthambo, zida zamagetsi, zoyendera, zomangamanga, zamankhwala ndi zina. Ulusi wa Aramid ndi ulusi wonunkhira wa polyamide, womwe umapangidwa ndi polima liniya yopangira (osachepera 85% ya chomangira cha amide chimalumikizidwa mwachindunji ndi mphete ziwiri zonunkhiritsa) zopangidwa ndi mphete ya amide yolumikizira kununkhira konunkhira (Ar-CONH-Ar). Unyolo waukulu umapangidwa ndi mphete yonunkhira komanso chomangira cha amide, ndipo mawonekedwe a mphete onunkhira amakhala olimba. Unyolo wa polima umatambasulidwa kuti ukhale ngati ndodo.
Nthawi yomweyo, mawonekedwe a mzere wa ma cell a cell amapangitsa kuti ma aramid fiber space agwiritsidwe ntchito kwambiri, kotero kuti voliyumu ya unit imatha kukhala ndi ma polima ambiri, motero mphamvuyo ndi yayikulu. Mosiyana ndi maunyolo osinthika a ma polima a molekyulu, unyolo waukulu wa para-aramid fiber umapangidwa makamaka ndi ndodo yopangidwa ndi mphete ya benzene. Chifukwa cha kukhalapo kwa mphete yayikulu ya benzene, gawo la unyolo wa ma molekyulu ndizovuta kuzungulira mkati, motero limapereka mawonekedwe olimba.
