I-Aramid fiber yazalwa ngasekupheleni kweminyaka yoo-1960.Ekuqaleni ibingaziwa njengesixhobo sokuphuhliswa kwendalo kunye nesixhobo esibalulekileyo sobuchule.Emva kokuphela kweMfazwe ebandayo, ifayibha ye-aramid, njengesixhobo sobuchwepheshe obuphezulu, yayisetyenziswa ngokubanzi kumasimi oluntu, kwaye ngokuthe ngcembe yaziwa.Kukho iindidi ezimbini ze-aramid fibers ezinexabiso elisebenzayo: enye i-meta-aramid fiber kunye ne-zigzag ye-molecular chain chain, ebizwa ngokuba yi-aramid fiber 1313 e-China;Enye yi-para-aramid fiber ene-linear molecular chain chain, ebizwa ngokuba yi-aramid fiber 1414 e-China.
Okwangoku, i-aramid fiber yinto ebalulekileyo yokhuselo lwelizwe kunye neshishini lomkhosi.Ukuze kuhlangatyezwane neemfuno zemfazwe yale mihla, iivesti ezingangenwa ziimbumbulu zamazwe ahambele phambili njengeUnited States neBritani zenziwe ngearamid fiber.Ubunzima beevesti ze-aramid bulletproof kunye nezigcina-ntloko ziphucule ngokufanelekileyo amandla okuphendula ngokukhawuleza kunye nokubulawa komkhosi.KwiMfazwe yeGulf, ii-aramid composite zazisetyenziswa kakhulu ziinqwelomoya zaseMelika nezaseFransi.Ukongeza kwizicelo zasemkhosini, isetyenziswe ngokubanzi njengesixhobo sobuchwepheshe obuphezulu kwi-aerospace, i-electromechanical, ukwakhiwa, iimoto, iimpahla zemidlalo kunye neminye imiba yoqoqosho lwelizwe.Kwi-aviation kunye ne-aerospace, i-aramid fiber igcina amandla amaninzi ngenxa yobunzima bayo kunye namandla aphezulu.Ngokutsho kwedatha yangaphandle, yonke ikhilogram yokunciphisa ubunzima ngexesha lokuqaliswa kwe-spacecraft ithetha ukunciphisa iindleko ze-1 yezigidi.Ukongeza, uphuhliso olukhawulezayo lwesayensi kunye netekhnoloji luvula indawo entsha yoluntu kwi-aramid fiber.Ngokweengxelo, iimveliso ze-aramid zisetyenziselwa i-bulletproof vests kunye nezigcina-ntloko, zibalelwa malunga ne-7-8%, kunye nezixhobo ze-aerospace kunye nezixhobo zemidlalo malunga ne-40%.Izixhobo zamathambo eTire, izinto zebhanti zokuhambisa kunye nezinye izinto ezimalunga ne-20%, kwaye iintambo zokuqina zithatha malunga ne-13%.Ishishini lamatayara laqala ukusebenzisa intambo ye-aramid ngobuninzi obukhulu ukunciphisa ubunzima kunye nokumelana nokuqengqeleka.
I-Aramid, eyaziwa ngokupheleleyo njenge "polyphenylphthalamide" kwaye ebizwa ngokuba yi-Aramid fiber ngesiNgesi, luhlobo olutsha lwe-high-tech synthetic fiber, eneempawu ezintle ezifana namandla aphezulu, i-modulus ephezulu, ukumelana nobushushu obuphezulu, i-asidi kunye nokumelana ne-alkali, ubunzima bokukhanya, ukugquma, umjikelo wobomi obude bokumelana nokuguga, njl. yegraphite yamandla aphezulu kunye namaxesha ama-3 efiber yeglasi.I-modulus ngama-2-3 amaxesha e-fiber yensimbi okanye i-fiber yeglasi, ubunzima buphindwe kabini kunocingo lwensimbi, kwaye ubunzima bumalunga ne-1/5 kuphela yocingo lwensimbi.Ukumelana nokushisa okuphezulu okuphezulu, ubushushu bokusetyenziswa kwexesha elide lee-degrees ezingama-300, ukumelana nobushushu obuphezulu bexesha elifutshane lama-586 degrees.Ukufunyanwa kwefayibha ye-aramid kuthathwa njengenkqubo yembali ebaluleke kakhulu kwintsimi yezinto.
