1.Hoʻokaʻawale ʻana i nā fiber Aramid
Hiki ke hoʻokaʻawale ʻia nā lāʻau Aramid i ʻelua mau ʻano nui e like me kā lākou mau ʻano kemika ʻokoʻa: hoʻokahi ʻano i hōʻike ʻia e ka wela wela, flame retardant meso-aramid, i kapa ʻia he poly(p-toluene-m-toluoyl-m-toluamide), i hoʻopau ʻia ʻo PMTA, i kapa ʻia ʻo Nomex i ka US, a me Aramid 1313 ma Kina; a ʻo ke ʻano ʻē aʻe e hōʻike ʻia e ka ikaika kiʻekiʻe, ka modulus elasticity kiʻekiʻe, a me ke kūpaʻa wela, i kapa ʻia ʻo poly(p-phenylene terephthalamide), i hoʻopau ʻia ʻo PPTA, ʻike ʻia ʻo Kevlar ma US, Technora ma Iapana, Twaron ma Netherlands, Tevlon ma Rusia, a me Tevlon ma Kina. ʻO P-phenylenediamine, i hoʻopau ʻia ʻo PPTA, ka inoa kālepa o ʻAmelika no Kevlar, Iapana no Technora, Netherlands no Twaron, Russia no Tevlon, Kina i kapa ʻia ʻo aramid 1414.

Aramida fiberhe kiʻekiʻe-mehana-kūʻokoʻa, kiʻekiʻe-ikaika, kiʻekiʻe-elastic kumu hoʻohālike o nā fibers, nā mea mechanical o ka inorganic fibers a me ka organic fibers, hana hana, density a me ka polyester fibers ua like. I ka manawa like, loaʻa iā ia ke kūpaʻa kemika maikaʻi loa, ka pale ʻana i ka radiation, ka pale ʻana i ka luhi, ke kūpaʻa dimensional a me nā waiwai maikaʻi ʻē aʻe a me ka resin rubber me kekahi mau waiwai adhesive. I kēia manawa, ʻelua mau ʻano o ka pulp a me ka fiber. E lilo i aerospace, rubber, resin industry, electronic and electrical equipment, transport, sports equipment and civil construction and other areas of new materials. ʻOi aku me ka hoʻomākaukau ʻana i ka fiber aramid o nā mea hana kiʻekiʻe aramid pepa composite hiki ke hoʻohana nui ʻia e like me ke kiʻekiʻe kiʻekiʻe o nā mea uila insulation, nā papa kaapuni i paʻi ʻia a me nā mea pale hawewe electromagnetic a me nā mea ʻē aʻe i mahalo nui ʻia.

2. Aramida FiberMorphology
1414 pulupulu melemele, 1313 pulupulu keokeo. E like me nā pulupulu pōkole (a i ʻole filament) a me ka pulupulu pulupulu (a i ʻole ka ua ua) ʻelua ʻano fiber. Hoʻohana nui ʻia ka filament i nā textiles, rubber a me nā māla ʻē aʻe, ka ʻoihana pepa e hoʻohana ana i ka staple fiber a me ka pulp fiber.
