ʻO nā olonā hana kiʻekiʻe ʻekolu ma ka honua i kēia lā: aramid, fiber kalapona, fiber polyethylene kaumaha molekala ultra-kiʻekiʻe, a me ka fiber polyethylene kaumaha molekala 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 kaumaha molekala 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. Ma ke kumu o ke kaʻina hana pultrusion fiber aramid ʻili i mālama ʻia, ua hoʻolauna pū ʻo Beihai i kahi resin vinyl kūpono no ka pultrusion fiber weight molecular ultra-kiʻekiʻe, a ua hoʻopili ʻia ma nā ʻāpana. ʻOi aku ka haʻahaʻa o ke kumukūʻai o kēia ʻano kumu i hoʻoikaika ʻia ma mua o ka fiber aramid 40%, akā he kiʻekiʻe kona mau waiwai flexural a me tensile.
