ʻO nā olonā hana kiʻekiʻe nui ʻekolu ma ka honua i kēia lā: aramid, fiber carbon, fiber polyethylene weight molecular ultra-kiʻekiʻe, a me ka fiber polyethylene weight molecular ultra-kiʻekiʻe (UHMWPE) ma muli o kona ikaika kikoʻī kiʻekiʻe a me ka modulus kikoʻī, hoʻohana ʻia i ka pūʻali koa, aerospace, nā huahana composite hana kiʻekiʻe (nā lako haʻuki, nā kaula, a me nā mea ʻē aʻe) ua hoʻohana nui ʻia i nā ʻoihana like ʻole. I kēia manawa, ua hoʻomohala ʻia ka ʻenehana fiber weight molecular ultra-kiʻekiʻe o Kina e nā lele a me nā palena. I kēia manawa, i ka ʻoihana kamaʻilio, ʻo ka mea nui ʻO ka fiber aniani i hoʻoikaika ʻia. I nā makahiki i hala iho nei, ua hoʻolaha ʻia hoʻi ma muli o ka hana piha o ka fiber aramid. Eia naʻe, ma muli o nā kumu like ʻole e like me ke kumukūʻai, ʻo ka mākeke no ka fiber aramid (KEVLAR) i hoʻoikaika ʻia i ke kaula fiber optic i hoʻoikaika ʻia i ka core Ke emi mālie nei, a ʻoi aku ka nui o nā mea hana a me nā mea hoʻohana e kālele ana i ka fiber UHMWPE, no ka mea, he kumukūʻai kūpono a me ka hana maikaʻi ʻo UHMWPE fiber reinforced core. Eia naʻe, ma muli o nā ʻano like ʻole o ka fiber (me ke kūpaʻa o ka mahana, a me nā mea ʻē aʻe), ua waiho ʻia nā koi kiʻekiʻe no ka hiki ke hana a me ka wettability o ka resin. Ua oʻo a hoʻopili pono kā mākou hui i nā resins vinyl i ke kaʻina hana pultrusion fiber aramid ʻili i mālama ʻia, ma kēia kumu, ua hoʻolauna i kahi resin vinyl kūpono no ka pultrusion fiber weight molekala kiʻekiʻe loa, a ua hoʻopili ʻia i nā ʻāpana. ʻO kēia ʻano kumu i hoʻoikaika ʻia he 40% haʻahaʻa ma mua o ke kumukūʻai o ka fiber aramid, akā he kiʻekiʻe aʻe kona mau waiwai flexural a me tensile.
