Ko te muka Aramid e kiia ana ko te polybenzoylenediamine, me te muka waro, ultra-high molecular weight polyethylene fiber me te toru o te ao nui o te muka mahi teitei, he iti te kiato, te kaha teitei, te modulus teitei, te kaha o te pāmahana teitei, te aukati i te waikura, te whakamaarama, kei te whakamahia whānuitia i roto i te hōia, aerospace, taputapu hiko, waka, hanga, hauora me etahi atu mara. Ko te muka Aramid he muka polyamide kakara, he mea hanga mai i te polymer linear synthetic (he iti rawa te 85% o te here amide e hono tika ana ki nga mowhiti kakara e rua) i tito mai i te here amide e hono ana i te mowhiti kakara (Ar-CONH-Ar). Ko te mekameka matua ko te mowhiti kakara me te here amide, a he pakari te hanganga mowhiti kakara. Ka horahia te mekameka polymer hei hanga i te ahua o te rakau.
I te wa ano, ko te hanganga raina o te mekameka ngota ka nui ake te tere o te whakamahi mokowhiti muka aramid, na reira ka taea e te roopu roopu te whakauru atu i te polymer, na te kaha ake. He rereke mai i nga mekameka rapoi polymer ngawari noa, ko te hanganga mekameka matua o te muka para-aramid te nuinga o te hanganga rapoi rakau-rite i hangaia e te mowhiti benzene. Na te mea he nui te whakakai benzene conjugated, he uaua te hurihanga o te wahanga mekameka ngota i roto, na reira ka whakaatu mai he hanganga maaro.
