Aramid fiber yakazvarwa mukupera kwema1960.Pakutanga yakanga isingazikanwi sechinhu chekusimudzira denga uye chinhu chakakosha chehurongwa.Mushure mekupera kweCold War, aramid fiber, seyepamusoro-tech fiber zvinhu, yakashandiswa zvakanyanya muminda yevagari, uye zvishoma nezvishoma yakazozivikanwa.Kune mhando mbiri dzearamid fibers dzine kukosha kwakanyanya: imwe ndeye meta-aramid fiber ine zigzag molecular chain chain, iyo inonzi aramid fiber 1313 muChina;Imwe ndeye para-aramid fiber ine mutsara mamorekuru cheni kurongeka, inonzi aramid fiber 1414 kuChina.
Parizvino, aramid fiber chinhu chakakosha chekudzivirira kwenyika uye indasitiri yemauto.Kuitira kuzadzisa zvinodiwa muhondo yemazuva ano, majasi asingapindi bara renyika dzakabudirira dzakadai seUnited States neBritain akagadzirwa nearamid fiber.Huremu hwema aramid bulletproof vests nehemeti zvakavandudza kukurumidza kupindura kugona uye kuuraya kwemauto.MuGulf War, ma aramid composite aishandiswa zvakanyanya nendege dzeAmerica neFrance.Pamusoro pekushandiswa kwechiuto, yave ichishandiswa zvakanyanya seyepamusoro-tech faibha zvinhu muaerospace, electromechanical, kuvaka, mota, zvinhu zvemitambo nezvimwe zvinhu zvehupfumi hwenyika.Mundege uye muchadenga, aramid faibha inochengetedza mafuta emagetsi akawanda nekuda kwehuremu hwayo uye simba rayo guru.Zvinoenderana nedata rekune dzimwe nyika, kilogiramu yega yega yekudzikisa huremu panguva yekuvhurwa kwespacecraft zvinoreva kudzikiswa kwemutengo wemadhora miriyoni.Pamusoro pezvo, kukurumidza kukura kwesainzi uye tekinoroji kuri kuvhura imwe nzvimbo itsva yevagari vearamid fiber.Sekureva kwemishumo, zvigadzirwa zvearamid zvinoshandiswa kune mabhururu mavheti uye ngowani, inoverengera inosvika 7-8%, uye zvinhu zvemuchadenga uye zvemitambo zvinokwana 40%.Matai skeleton zvinhu, conveyor bhandi zvinhu uye zvimwe zvinhu zvinokwana 20%, uye tambo dzesimba-refu dzinoita 13%.Indasitiri yematayi yakatangawo kushandisa tambo yearamid muhuwandu hukuru kuderedza huremu uye kuramba.
Aramid, inonyatsozivikanwa se "polyphenylphthalamide" uye yakadanwa seAramid fiber muChirungu, imhando nyowani yemhando yepamusoro-tech synthetic fiber, ine zvinhu zvakanakisa senge Ultra-yakakwirira simba, yakakwira modulus, yakakwirira tembiricha kuramba, asidhi uye alkali kuramba, uremu huremu, kuvharisa, kutenderera kwehupenyu hurefu hwekuramba kuchembera, etc. Simba rayo rakakura kupfuura 28g/denier, inova 5-6 nguva yewaya yemhando yepamusoro yesimbi, ka2 iyo yewaya-yakasimba yenaironi, 1.6 nguva ye-high-simba graphite uye 3 nguva iyo yegirazi fiber.Iyo modulus ndeye 2-3 nguva yewaya yesimbi kana girazi faibha, kusimba kwakapetwa kaviri kwewaya yesimbi, uye huremu hunenge 1/5 chete yewaya yesimbi.Yakanakisa kupisa tembiricha kuramba, kushandiswa kwenguva refu tembiricha ye300 madhigirii, yenguva pfupi-yepamusoro tembiricha yekudzivirira ye586 madhigirii.Kuwanikwa kwearamid fiber kunoonekwa seyakanyanya kukosha nhoroondo mundima yezvigadzirwa.
