Aramid faibha inonzi polybenzoylenediamine, uye kabhoni faibha, ultra-yakakwirira molecular weight polyethylene faibha uye matatu makuru epasirese akakwira-performance faibha, diki density, simba rakawanda, high modulus, high tembiricha kuramba, corrosion resistance, insulation, inoshandiswa zvakanyanya mu mauto, aerospace, midziyo yemagetsi, chokufambisa, kuvaka, zvokurapa nezvimwe minda.Aramid fiber is a synthetic aromatic polyamide fiber, iyo inogadzirwa neine synthetic linear polymer (inokwana 85% yeamide bond yakabatana zvakananga kune maviri anonhuwirira mhete) inoumbwa neamide bond inobatanidza inonhuwirira mhete (Ar-CONH-Ar).Cheni huru inoumbwa nemhete inonhuhwirira uye iyo amide bond, uye inonhuhwirira mhete chimiro chakasimba.Iyo polymer cheni yakatambanudzwa kuita danda-rakafanana chimiro.
Panguva imwecheteyo, iyo mutsara chimiro cheiyo molecular cheni inoita kuti aramid fiber nzvimbo yekushandiswa ive yakakwira, saka vhoriyamu yeyuniti inogona kugarisa yakawanda polymer, saka simba racho rakakwira.Yakasiyana kubva kune yakajairwa inochinjika polymer molecular cheni, iyo huru cheni chimiro chepara-aramid fiber inonyanya kuumbwa netsvimbo-yakaita semolecular chimiro chakaumbwa nebenzene mhete.Nekuda kwekuvapo kwehombe conjugated benzene ring, iyo molecular chain segment inonetsa kutenderera nechomukati, saka inopa mutsara wakaomarara chimiro.
