ʻO nā olonā hana nui ʻekolu ma ka honua i kēia lā: ʻo ke olonā aramid, ke olonā kalapona, a me ke olonā polyethylene kaumaha molekala ultra-kiʻekiʻe, a me ke olonā polyethylene kaumaha molekala ultra-kiʻekiʻe (UHMWPE) he mau ʻano o ka ikaika kikoʻī kiʻekiʻe a me ka modulus kikoʻī. Ua hoʻohana nui ʻia nā huahana hui hana (nā lako haʻuki, nā kaula, a me nā mea ʻē aʻe) ma nā ʻoihana like ʻole. I kēia manawa, ua holomua nui ka ʻenehana olonā kaumaha molekala ultra-kiʻekiʻe o Kina i nā makahiki i hala iho nei. ʻO ka hoʻoikaika ʻana o ke olonā aniani ka mea nui, a i nā makahiki i hala iho nei, ua hoʻolaha ʻia i kahi ʻano ma muli o nā waiwai piha o ke olonā aramid. Eia nō naʻe, ma muli o nā kumu like ʻole e like me ke kumukūʻai, ke emi mālie nei ka mākeke o ke olonā aramid (KEVLAR) i hoʻoikaika ʻia i ke kaula optical i hoʻoikaika ʻia, a e kālele ana nā mea hana a me nā mea hoʻohana i ke olonā UHMWPE, no ka mea, he kumukūʻai kūpono a me ka hana maikaʻi o ke olonā polyethylene kaumaha molekala ultra-kiʻekiʻe. Eia nō naʻe, ma muli o nā ʻano like ʻole o ke olonā (me ke kūʻē ʻana i ka mahana, a me nā mea ʻē aʻe), ua kau ʻia nā koi kiʻekiʻe ma ka hiki ke hana a me ka maʻalahi o ka resin. Ua hoʻopili pono ka ʻoihana i ka resin vinyl i ka resin i mālama ʻole ʻia i nā makahiki he nui i hala. Ma ke kumu o ke kaʻina hana pultrusion fiber aramid ʻili, ua hoʻolauna ʻia ka resin vinyl kūpono no ka pultrusion fiber weight molecular kiʻekiʻe loa, a ua hoʻopili ʻia ma nā ʻāpana. ʻO ke kumukūʻai o kēia kumu hoʻoikaika he 40% haʻahaʻa ma mua o ka fiber aramid, akā he kiʻekiʻe aʻe kona mau waiwai flexural a me tensile.
